Whether zero-arg tools need a dedicated overload. + +How would this signature **not** be the dedicated overload: + +```java +ToolDefinition zeroArg = ToolDefinition.from( + "zero_args", + "Tool with zero args", + () -> { + return "OK"; + }); +``` + +I don't recall what a lambda with no args looks like, but such a lambda is the last argument to this overload. + +### 14:42 Response + +It would be the dedicated zero-arg overload. + +Your example is exactly the shape to add: + +ToolDefinition.from(String name, String description, ToolFn0 handler) + +(or  Supplier  if you want JDK functional types). + +For async parity, you’d likely also want: + +ToolDefinition.from(String name, String description, AsyncToolFn0 handler) +// where handler returns CompletableFuture + +So yes: a no-arg lambda as the last parameter is the clean, dedicated zero-arg API. + +### 14:42 Prompt + +Why would I **not** want a Supplier  for JDK functional types? Isn't this the most idiomatic way? + +### 14:44 Response + +You’re right— Supplier  is the most idiomatic Java choice for sync zero-arg handlers. + +You’d avoid it only if you want consistency with a custom tool-function family ( ToolFn0 ,  ToolFn1 , ...), or if you need behavior  Supplier  can’t express cleanly (for example checked exceptions, unless you wrap them, or a separate async SAM instead of  Supplier> ). + +So the practical recommendation is: + +• Use  Supplier  for sync zero-arg overload. +• Use a dedicated async SAM for async zero-arg overload (clearer than  Supplier> ). + +### 14:44 Prompt + +Why is this tools-as-lambda tending to bifurcate into a dual "one for async, another for non-async" pattern? + +### 14:45 Response + +Because Java’s type system doesn’t give a clean single-SAM shape that is both ergonomic and unambiguous for: + +•  R  +•  CompletableFuture  + +If you try one overload, you usually end up with awkward signatures ( Supplier ,  Function<..., ?> ) and runtime branching on return type, or ambiguous lambda inference. + +So APIs split into sync + async mostly for clarity and type inference: + +• sync: simple lambda, returns  R  +• async: simple lambda, returns  CompletableFuture  + +It’s less about architecture and more about making call sites readable and compile-time-safe. + +### 14:45 Prompt + +Pardon my ignorance, but I am unfamiliar with this usage of the acronym SAM. Please make me smart. + +### 14:47 Response + +SAM means Single Abstract Method. + +In Java, a lambda can be assigned to any interface that has exactly one abstract method (a “functional interface”), like  Supplier ,  Function ,  Runnable , etc. + +Example: + +Supplier s = () -> "OK"; // lambda matches get() + + Supplier  is SAM because it has one abstract method:  T get() . + +So when people say “SAM shape,” they mean “the functional-interface method signature the lambda must match.” + +### 14:48 Prompt + +You stated: + +> • Use  Supplier  for sync zero-arg overload. + +So this would be + +``` +ToolDefinition.from(String name, String description, Supplier handler) +``` + +> • Use a dedicated async SAM for async zero-arg overload (clearer than  Supplier> ). + +How about + +``` +ToolDefinition.fromAysnc(String name, String description, Supplier handler) +``` + +Would that meet the requirements in the zero-arg case? + +### 14:53 Response + +Almost—not as written. + +If  fromAsync  takes  Supplier , it’s still a sync signature unless you define  R  to be async. For zero-arg async, it should be one of: + +ToolDefinition.fromAsync(String name, String description, Supplier> handler) + +or (clearer API surface): + +ToolDefinition.fromAsync(String name, String description, AsyncSupplier handler) +// interface AsyncSupplier { CompletableFuture get(); } + +So  fromAsync(..., Supplier)  only works if callers pass  R = CompletableFuture , which is less explicit and easier to misuse. + + +### 14:53 Prompt + + +Where are you getting this `AsyncSupplier`? I see there is https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/function/Supplier.html but no corresponding async version. + +### 14:54 Response + + +You’re correct—there is no JDK  AsyncSupplier . + +I meant a custom interface you would define (if you choose that route), for example: + +@FunctionalInterface +public interface AsyncSupplier { + CompletableFuture get(); +} + +So your realistic choices are: + +1.  fromAsync(..., Supplier> handler)  using only JDK types, or +2.  fromAsync(..., AsyncSupplier handler)  with a tiny custom SAM for readability. + + +### 14:54 Prompt + + + +Who coined this SAM acronym? + +### 14:55 Response + + +There isn’t a single credited inventor. + +SAM (“Single Abstract Method”) was community/OpenJDK terminology that became mainstream during Java 8 lambda design work (JSR 335), especially in materials from the Oracle/OpenJDK lambda expert group led by Brian Goetz. + + +### 14:56 Prompt + +I have added `C:\Users\edburns\workareas\langchain4j-00-main`.

Evaluating the design we currently elicited, how does that answer the three unknowns for 3.3? + +### 16:34 Prompt + + Params.of(...)  helps, but it does not by itself answer all three unknowns. It mainly answers ordering/composition. + +I’d say the current elicited design answers 3.3 like this: + +• 1. Defaults representation and validation by type + Params.of(...)  only works cleanly if each  Param  carries a type token (for example  Param  or  Class ). Then  defaultValue  can mirror the annotation API and be validated against that type. +• 2. Optionality vs. default values +Reuse the current annotation rule: +•  required=true  by default +• non-empty default means effectively optional +• reject  required=true  + defaultValue present +• 3. Whether descriptions are required by policy + Params.of(...)  does not settle that. Policy is separate. My recommendation: keep descriptions allowed-but-not-forced in API, and enforce stricter quality later if desired. + +So:  Params.of(...)  is a good container, but typed  Param  is the real key. + +### 16:34 Prompt + +So what would `Params` look like with typed Param? + +### 16:35 Response + +``` +Something like this: + +package com.github.copilot.tool; + +import java.util.List; + +public final class Params { + + private final List> values; + + private Params(List> values) { + this.values = List.copyOf(values); + } + + public static Params of(Param... values) { + return new Params(List.of(values)); + } + + public List> values() { + return values; + } +} + +And typed  Param : + +package com.github.copilot.tool; + +public final class Param { + + private final Class type; + private final String name; + private final String value; + private final boolean required; + private final String defaultValue; + + private Param(Class type, String name, String value, boolean required, String defaultValue) { + this.type = type; + this.name = name; + this.value = value; + this.required = required; + this.defaultValue = defaultValue; + } + + public static Param of(Class type, String name, String value) { + return new Param<>(type, name, value, true, ""); + } + + public Param required(boolean required) { + return new Param<>(type, name, value, required, defaultValue); + } + + public Param defaultValue(String defaultValue) { + return new Param<>(type, name, value, false, defaultValue); + } + + public Class type() { return type; } + public String name() { return name; } + public String value() { return value; } + public boolean required() { return required; } + public String defaultValue() { return defaultValue; } +} +``` + +Usage: + +``` +Params params = Params.of( + Param.of(String.class, "query", "Search query"), + Param.of(Integer.class, "limit", "Max results").defaultValue("10") +); +``` + +That gives ordered, typed parameter metadata. + + +### 16:38 Prompt + +Here is your complete `Param`.

Both classes are package-private per resolution 3.8 (no public internal helpers). coerce() takes Map to avoid a cyclic rpc dependency. Updates Phase 4.3 checkbox in plan file.

I am concerned that the Copilot session of the agent may get too long when executing the top level `copilot-sdk/.github/skills/shepherd-task/SKILL.md` skill. + +Is that a valid concern? + +### 13:48 Response + +Yes, that's a valid concern. From our #1840 experience: + +• Phase 1 alone required ~30 minutes of polling + CI evaluation +• Phase 2 went through 6 rounds of review, each involving: fetching comments, reading code, making edits, running tests, committing — that's substantial context accumulation +• The combined skill would stack both phases in one session + +The risk is the LLM loses coherence or starts hallucinating as context fills up, especially during Phase 2's iterative review loop. + +Mitigation options: + +1. Keep the skills separate — invoke Phase 1 and Phase 2 as independent sessions (human triggers Phase 2 after Phase 1 completes). The orchestrator  shepherd-task  becomes documentation rather than a single-session execution. +2. Add a "compact context" instruction at the Phase 1→Phase 2 boundary, telling the LLM to summarize state and discard intermediate polling output. +3. Rely on infinite sessions — the SDK supports compaction events that compress older context automatically. +4. Split Phase 2 internally — each review round could be a separate invocation, with state passed via the PR itself (comments, commits). + +Which direction interests you? Or would you prefer to keep the orchestrator as-is and see if context length becomes an actual problem on the next run? + +### 13:48 Prompt + +The whole point of this is to get long running orchestrated actions. My job is to keep the agents busy. + +Is there a slash command to cause the CLI to start a new session? + +If so, could we bake that into the `copilot-sdk/.github/skills/shepherd-task/SKILL.md` and pepper it in between the called skills? + +### 13:49 Response + +I see  /compact  and  /new  commands: + +•  /compact  — Summarizes conversation history to reduce context window usage. You can provide focus instructions (e.g.,  /compact focus on the PR number and current step ). +•  /new  — Starts a new conversation (fresh session, loses all context). + +The problem: Neither works well baked into a skill: + +•  /new  wipes all state — the Phase 2 skill wouldn't know the PR number, branch, etc. +•  /compact  reduces context but doesn't reset it — and you can't invoke slash commands from within a skill's execution (they're user-level CLI commands, not something the LLM can emit programmatically). + +What would actually work: Add a  /compact  instruction at the Phase 1→Phase 2 boundary in the orchestrator skill, telling the LLM to explicitly request compaction: + +After Phase 1 completes, run `/compact` with focus: "Retain TASK_ISSUE, PR number, branch name, BASE_BRANCH, REPO, and current step." + +The LLM can invoke  /compact  as a tool during execution in  --yolo  mode.

Automate the lifecycle of a child **Task** issue from "assigned to Copilot" through CI passing and review-agent feedback resolution, stopping just before marking the PR as **Ready for review**. +11. +12. ## Inputs +13. +14. - `TASK_ISSUE`: The issue number (e.g., `1850`) or URL of the child task to shepherd. +15. - `BASE_BRANCH`: The base branch the task PR should target (default: `upstream/edburns/1810-java-tool-ergonomics-tool-as-lambda`). +16. - `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). +17. +18. ## Prerequisites +19. +20. - `gh` CLI authenticated with sufficient permissions (issues, PRs, actions, reviews). +21. - The task issue already exists and has a clear description of work to do. +22. - The base branch exists in the repository. +23. +24. --- +25. +26. ## Procedure +27. +28. ### Step 1: Assign the task to @Copilot +29. +30. First, prepend an instruction to the issue body telling Copilot which base branch to use. This must happen **before** assignment to avoid a race condition where Copilot targets `main` instead. +31. +32. **Idempotency:** If the issue body already starts with `**Base branch:**`, skip the prepend (it was already done in a prior run). +33. +34. ```bash +35. # Check if already prepended (idempotency guard) +36. CURRENT_BODY=$(gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body') +37. if echo "$CURRENT_BODY" | head -1 | grep -q '^\*\*Base branch:\*\*'; then +38. echo "Base branch instruction already present — skipping prepend." +39. else +40. # Prepend base branch instruction (use --body-file to preserve markdown formatting) +41. gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body' > /tmp/issue-body-$TASK_ISSUE.md +42. cat > /tmp/issue-body-$TASK_ISSUE-new.md <
    > /tmp/issue-body-$TASK_ISSUE-new.md +51. gh issue edit $TASK_ISSUE -R $REPO --body-file /tmp/issue-body-$TASK_ISSUE-new.md +52. rm -f /tmp/issue-body-$TASK_ISSUE.md /tmp/issue-body-$TASK_ISSUE-new.md +53. fi +54. ``` +55. +56. > **PowerShell equivalent** (when running on Windows): +57. > ```powershell +58. > $body = gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body' | Out-String +59. > if ($body.TrimStart().StartsWith("**Base branch:**")) { +60. > Write-Host "Base branch instruction already present - skipping prepend." +61. > } else { +62. > $instruction = @" +63. > **Base branch:** Create your PR targeting ``$BASE_BRANCH`` (not ``main``). +64. > +65. > **Requirement:** When you open the PR, the very first thing you put in the description must be ``Fixes #$TASK_ISSUE`` where the issue number is this issue for which the PR aims to implement the work. +66. > +67. > -------- +68. > +69. > "@ +70. > $newBody = $instruction + $body +71. > $tmpFile = [System.IO.Path]::GetTempFileName() +72. > Set-Content -Path $tmpFile -Value $newBody -NoNewline +73. > gh issue edit $TASK_ISSUE -R $REPO --body-file $tmpFile +74. > Remove-Item $tmpFile +75. > } +76. > ``` +77. +78. Then assign: +79. +80. ```bash +81. gh issue edit $TASK_ISSUE --add-assignee "@copilot" -R $REPO +82. ``` +83. +84. This triggers Copilot to: +85. 1. Create a topic branch from `$BASE_BRANCH`. +86. 2. Open a draft PR targeting `$BASE_BRANCH`. +87. 3. Push initial commits. +88. +89. **Fallback:** After the PR is created (Step 2), verify it targets `$BASE_BRANCH`. If Copilot ignored the instruction, fix the base: +90. +91. ```bash +92. gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" +93. ``` +94. +95. ### Step 2: Find the corresponding PR +96. +97. Look for the corresponding PR created and mentioned in the issue. The issue will often have text like "linked a pull request that will close this issue". First, try to find the PR this way. If you find it, let `PR_NUMBER` be that PR number. +98. +99. If that doesn't work, wait for Copilot to create the PR. +100. +101. Poll until a PR exists with the task issue linked or with a head branch referencing the issue number. +102. +103. ```bash +104. # Poll every 30 seconds for up to 10 minutes +105. TIMEOUT=600 +106. INTERVAL=30 +107. ELAPSED=0 +108. +109. while [ $ELAPSED -lt $TIMEOUT ]; do +110. PR_NUMBER=$(gh pr list -R $REPO --state open --json number,title,headRefName \ +111. --jq ".[] | select(.title | test(\"$TASK_ISSUE\"; \"i\")) | .number" | head -1) +112. +113. if [ -n "$PR_NUMBER" ]; then +114. break +115. fi +116. +117. sleep $INTERVAL +118. ELAPSED=$((ELAPSED + INTERVAL)) +119. done +120. ``` +121. +122. If no PR is found after timeout, report failure and stop. +123. +124. Once the PR is found, verify and fix the base branch if needed: +125. +126. ```bash +127. # Check the PR targets the correct base branch +128. ACTUAL_BASE=$(gh pr view $PR_NUMBER -R $REPO --json baseRefName --jq '.baseRefName') +129. if [ "$ACTUAL_BASE" != "$BASE_BRANCH" ]; then +130. gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" +131. fi +132. ``` +133. +134. ### Step 3: Wait for initial commits and workflow trigger +135. +136. After the PR is created, Copilot pushes commits which trigger workflow runs. These runs require approval because every Copilot push triggers the "Approve workflows to run" gate. +137. +138. You may be coming to this PR after all the runs have been manually approved. In that case, you need to wait for the runs to complete, then, skip to step 6. Here is how you wait for the runs to complete. +139. +140. ```bash +141. gh pr checks $PR_NUMBER -R $REPO --watch +142. ``` +143. +144. Otherwise, wait for runs to appear in `action_required` status: +145. +146. ```bash +147. # Wait for workflow runs needing approval +148. gh run list -R $REPO --branch "$JTBDTASK_BRANCH" --status action_required \ +149. --json databaseId,name,status --jq '.[].databaseId' +150. ``` +151. +152. ### Step 4: Approve pending workflow runs +153. +154. For each run in `action_required` status on the PR's branch, re-run it. The correct mechanism is `gh run rerun` (the `POST .../actions/runs/{id}/approve` endpoint is for fork PRs only and will return HTTP 403 here). +155. +156. ```bash +157. # Get all action_required runs for the PR branch +158. PENDING_RUNS=$(gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ +159. --json databaseId,conclusion --jq '.[] | select(.conclusion == "action_required") | .databaseId') +160. +161. for RUN_ID in $PENDING_RUNS; do +162. gh run rerun $RUN_ID -R $REPO +163. done +164. ``` +165. +166. ### Step 5: Wait for workflow runs to complete +167. +168. ```bash +169. # Watch all runs on the branch until they complete +170. # Use gh pr checks with --watch for convenience +171. gh pr checks $PR_NUMBER -R $REPO --watch --fail-fast +172. ``` +173. +174. Alternatively, poll with: +175. +176. ```bash +177. gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ +178. --json databaseId,status,conclusion,name \ +179. --jq '.[] | select(.status != "completed")' +180. ``` +181. +182. ### Step 6: Evaluate workflow results +183. +184. **Note:** Ignore failures from the "Block remove-before-merge paths" / "No remove-before-merge directories" workflow. This failure is expected on feature branches and is not a real problem. +185. +186. ```bash +187. # Get check results, excluding the expected "Block remove-before-merge paths" failure +188. RESULTS=$(gh pr checks $PR_NUMBER -R $REPO --json name,state,bucket \ +189. --jq '.[] | select(.bucket == "fail") | select(.name != "No remove-before-merge directories")') +190. ``` +191. +192. If there are real failures (after excluding the expected one), proceed to Step 7. If all pass, proceed to Step 8. +193. +194. ### Step 7: Request changes from Copilot (iteration loop) +195. +196. **Max iterations: 20** +197. +198. When CI fails or review agents flag problems: +199. +200. #### 7.1: Gather failure details +201. +202. ```bash +203. # Get failed run IDs +204. FAILED_RUNS=$(gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ +205. --status completed --json databaseId,conclusion,name \ +206. --jq '.[] | select(.conclusion == "failure") | .databaseId') +207. +208. # Get logs for failed runs (only failed steps) +209. for RUN_ID in $FAILED_RUNS; do +210. gh run view $RUN_ID -R $REPO --log-failed +211. done +212. ``` +213. +214. #### 7.2: Gather review agent comments +215. +216. ```bash +217. # Get review comments on the PR +218. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ +219. --jq '.[] | select(.user.type == "Bot") | {user: .user.login, body: .body}' +220. +221. # Also get issue-level comments (review agents sometimes post there) +222. gh pr view $PR_NUMBER -R $REPO --comments --json comments \ +223. --jq '.comments[] | select(.author.login | test("bot|copilot|agent"; "i")) | {author: .author.login, body: .body}' +224. ``` +225. +226. #### 7.3: Compose and submit a "Request changes" review +227. +228. Analyze the failures and compose a hybrid message: relevant log excerpts plus a short targeted instruction for Copilot. +229. +230. ```bash +231. # Submit review requesting changes, @mentioning Copilot +232. gh pr review $PR_NUMBER -R $REPO --request-changes --body "$REVIEW_BODY" +233. ``` +234. +235. The `$REVIEW_BODY` should follow this format: +236. +237. ``` +238. @copilot Please fix the following issues: +239. +240. ## CI Failure: [workflow name] +241. +242. +243. +244. **Fix:** [Short, specific instruction on what to change] +245. +246. ## Review Comment from [bot name] +247. +248. > [quoted comment] +249. +250. **Fix:** [Short, specific instruction on what to change] +251. ``` +252. +253. #### 7.4: Wait for Copilot to push fixes +254. +255. After submitting the review, wait for new commits on the branch: +256. +257. ```bash +258. # Get current HEAD SHA +259. CURRENT_SHA=$(gh pr view $PR_NUMBER -R $REPO --json headRefOid --jq '.headRefOid') +260. +261. # Poll for new commits (up to 10 minutes) +262. TIMEOUT=600 +263. INTERVAL=30 +264. ELAPSED=0 +265. +266. while [ $ELAPSED -lt $TIMEOUT ]; do +267. NEW_SHA=$(gh pr view $PR_NUMBER -R $REPO --json headRefOid --jq '.headRefOid') +268. if [ "$NEW_SHA" != "$CURRENT_SHA" ]; then +269. break +270. fi +271. sleep $INTERVAL +272. ELAPSED=$((ELAPSED + INTERVAL)) +273. done +274. ``` +275. +276. #### 7.5: Loop back +277. +278. Return to **Step 4** (approve workflows) and repeat. Track iteration count. If 20 iterations are exhausted without all checks passing, stop and report: +279. +280. ``` +281. SHEPHERD FAILED: Exhausted 20 iterations on PR #$PR_NUMBER for task #$TASK_ISSUE. +282. Manual intervention required. +283. ``` +284. +285. ### Step 8: Address pre-Ready-for-Review comments +286. +287. Even when CI passes, review agents (e.g., "Copilot code review", "SDK Consistency Review Agent") may leave comments that should be addressed before marking ready. +288. +289. #### 8.1: Check for unresolved review comments +290. +291. ```bash +292. # Get all review comments that haven't been resolved +293. gh api "/repos/$REPO/pulls/$PR_NUMBER/reviews" \ +294. --jq '.[] | select(.state == "CHANGES_REQUESTED") | {user: .user.login, body: .body}' +295. +296. # Get pending review threads +297. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ +298. --jq '.[] | select(.user.type == "Bot") | {id: .id, user: .user.login, body: .body, path: .path, line: .line}' +299. ``` +300. +301. #### 8.2: If unresolved comments exist, iterate +302. +303. Use the same pattern as Step 7: compose a review requesting changes with specific instructions, wait for Copilot to push, approve workflows, and check results. This shares the same 20-iteration budget. +304. +305. ### Step 9: Final status report +306. +307. When all checks pass and no unresolved review comments remain: +308. +309. ``` +310. SHEPHERD COMPLETE: PR #$PR_NUMBER for task #$TASK_ISSUE is ready to review for marking as **Ready to review**. +311. All CI checks pass. No unresolved review comments. +312. Next step: Mark as Ready for Review (use separate skill). +313. ``` +314. +315. --- +316. +317. ## Error handling +318. +319. - **PR not created within 10 minutes**: Report and stop. +320. - **Copilot doesn't push after review request within 10 minutes**: Report and stop. +321. - **20 iterations exhausted**: Report and stop. +322. - **API errors**: Retry up to 3 times with 10-second backoff, then report and stop. +323. +324. ## Notes +325. +326. - This skill runs in a `copilot --yolo` session on a Dev Box, executing as the authenticated user. +327. - The skill does NOT mark the PR as "Ready for review" — that is a separate skill. +328. - The `gh api .../actions/runs/{id}/approve` endpoint is the programmatic equivalent of the "Approve and run" button in the GitHub UI. +329. - Review comments from bots/agents are treated the same as CI failures for iteration purposes. +330. - **Do NOT edit any plan/checklist files** (e.g., `1810-ignorance-reduction-for-implementation-plan.md`) to mark tasks as complete.

    +300 lines + +```` +1. --- +2. name: shepherd-task-from-ready-to-merged-to-base +3. description: "Use this skill to shepherd a task PR from 'Ready for review' through Copilot code review, local comment resolution, and merge to the specified base branch." +4. --- +5. +6. # Skill: Shepherd Task from Ready for Review to Merged +7. +8. ## Purpose +9. +10. Automate the lifecycle of a task PR from marking as **Ready for review** through Copilot code review comment resolution and merge to the specified base branch. This is a follow-up skill intended to be run after `shepherd-task-from-assignment-to-ready`. +11. +12. ## Inputs +13. +14. - `TASK_ISSUE`: The issue number (e.g., `1850`) or URL of the child task. +15. - `BASE_BRANCH`: The base branch the task PR should target (e.g., `edburns/1810-java-tool-ergonomics-tool-as-lambda`). +16. - `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). +17. +18. ## Prerequisites +19. +20. - The `shepherd-task-from-assignment-to-ready` skill has completed successfully for this task. +21. - `PR_NUMBER` is known (the PR created by Copilot for this task). For discussion: `jtbdtask-pr`. +22. - `gh` CLI authenticated with sufficient permissions. +23. - The PR is currently in draft state with all CI checks passing. +24. +25. --- +26. +27. ## Procedure +28. +29. ### Step 0: Find the PR +30. +31. Look for the corresponding PR created and mentioned in the issue. The issue will often have text like "linked a pull request that will close this issue". First, try to find the PR this way. If you find it, let `PR_NUMBER` be that PR number. +32. +33. If you don't find it, fail the skill and report the error. +34. +35. ### Step 1: Mark the PR as Ready for Review +36. +37. ```bash +38. gh pr ready $PR_NUMBER -R $REPO +39. ``` +40. +41. ### Step 2: Wait for Copilot code review agent to complete +42. +43. The act of marking as Ready for Review triggers the Copilot code review agent. Wait for it to post its findings. +44. +45. Poll the PR comments looking for a batch header matching this pattern: +46. +47. ``` +48. ## Copilot's findings +49. +50. - **Files reviewed:** X/Y changed files +51. - **Comments generated:** N +52. ``` +53. +54. ```bash +55. # Poll every 30 seconds for up to 10 minutes +56. TIMEOUT=600 +57. INTERVAL=30 +58. ELAPSED=0 +59. +60. while [ $ELAPSED -lt $TIMEOUT ]; do +61. FINDINGS=$(gh api "/repos/$REPO/pulls/$PR_NUMBER/reviews" \ +62. --jq '.[] | select(.body | test("Copilot.s findings")) | {id: .id, body: .body}' | tail -1) +63. +64. if [ -n "$FINDINGS" ]; then +65. break +66. fi +67. +68. sleep $INTERVAL +69. ELAPSED=$((ELAPSED + INTERVAL)) +70. done +71. ``` +72. +73. Search for similar text to identify the batch of review findings (`jtbdtask-pr-comments`). +74. +75. If **Comments generated: 0** (or no comments for this round), skip to **Step 18**. +76. +77. When `jtbdtask-pr-comments` has been identified, proceed. +78. +79. ### Step 3: Determine N (number of comments) +80. +81. Extract the number of comments from the **Comments generated:** line in the findings header. There will be exactly N individual review comments in this batch to address. +82. +83. ### Step 4: Fetch upstream and set up local worktree +84. +85. ❌❌❌ This part of the work does not use the remote agent. All comment resolution is done locally. ❌❌❌ +86. +87. ```bash +88. # Fetch upstream to get the topic branch +89. git fetch upstream +90. +91. # Get the currently logged in username +92. GH_CURRENT_USER=$(gh api /user --jq '.login') +93. +94. # Get the topic branch name for the PR +95. JTBDTASK_BRANCH=$(gh pr view $PR_NUMBER -R $REPO --json headRefName --jq '.headRefName') +96. +97. # Create a worktree for local review work +98. git worktree add "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" "upstream/$JTBDTASK_BRANCH" +99. ``` +100. +101. For discussion, this worktree is the `jtbdtask-pr-comments-comment-worktree`. +102. +103. ### Step 5: Gather all review comments +104. +105. ```bash +106. # Get all review comments from the Copilot code review batch +107. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ +108. --jq '.[] | select(.user.login == "copilot-pull-request-reviewer") | {id: .id, path: .path, line: .line, body: .body, in_reply_to_id: .in_reply_to_id}' +109. ``` +110. +111. Identify each individual comment. Each has a unique `id` (e.g., `discussion_r3456155645`-style reference). For discussion, each is a `jtbdtask-pr-comments-comment`. +112. +113. ### Step 6: Address each review comment locally +114. +115. For each review comment (`jtbdtask-pr-comments-comment`), working in the `jtbdtask-pr-comments-comment-worktree`: +116. +117. #### 6.1: Evaluate the comment +118. +119. - Carefully consider the comment and judge its merit. +120. - **If there is no merit:** mark the comment as resolved with an explanatory note (defer the resolution reply until Step 13). +121. - **If there is merit:** evaluate the suggested remedy. +122. - If you agree with the suggested remedy, proceed with it. +123. - If you disagree with the suggested remedy, devise a better remedy and proceed with that. +124. +125. #### 6.2: Implement the fix +126. +127. - Implement the remedy in the `jtbdtask-pr-comments-comment-worktree`. +128. - Use the appropriate language coding skill in `.github/skills/` to know how to run tests. +129. - ❌❌❌ DO NOT RUN THE FULL TEST SUITE at this stage. ❌❌❌ Only run the tests directly related to the fix, in isolation. +130. - **If the commit has to do with Java, YOU MUST ALWAYS RUN `mvn spotless:apply` in the java directory before each commit.** +131. +132. #### 6.3: Commit locally (do not push) +133. +134. - Once the relevant tests pass, commit the fix. +135. - ❌❌❌ Do NOT push yet. ❌❌❌ +136. - Keep track of the commit hash — you will need it when replying to the review comment. +137. +138. ### Step 7: Push all fixes to upstream +139. +140. Once **all** N review comments have been addressed locally: +141. +142. ```bash +143. # Push from the worktree to upstream +144. cd "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" +145. git push upstream HEAD:$JTBDTASK_BRANCH +146. ``` +147. +148. ### Step 8: Reply to each review comment and resolve the thread +149. +150. For each `jtbdtask-pr-comments-comment`: +151. +152. 1. State what you did to address the comment. If the action corresponds to a commit, include the hash: "Fixed in ``". +153. 2. Reply to the comment. +154. 3. Resolve the review thread. +155. +156. To reply to the comment: +157. +158. ```bash +159. # Reply to a specific review comment +160. gh api --method POST "/repos/$REPO/pulls/$PR_NUMBER/comments/$COMMENT_ID/replies" \ +161. -f "body=Fixed in $COMMIT_HASH. [explanation of the fix]" +162. ``` +163. +164. To resolve the thread, use the GraphQL API (the REST API does not support thread resolution): +165. +166. ```bash +167. # 1. Get the GraphQL thread node ID for the comment +168. THREAD_ID=$(gh api graphql -F number=$PR_NUMBER -f query=' +169. query($number: Int!) { +170. repository(owner: "github", name: "copilot-sdk") { +171. pullRequest(number: $number) { +172. reviewThreads(first: 100) { +173. nodes { +174. id +175. isResolved +176. comments(first: 1) { nodes { databaseId } } +177. } +178. } +179. } +180. } +181. }' --jq ".data.repository.pullRequest.reviewThreads.nodes[] | select(.comments.nodes[0].databaseId == $COMMENT_ID) | .id") +182. +183. # 2. Resolve the thread +184. gh api graphql -f query=" +185. mutation { +186. resolveReviewThread(input: {threadId: \"$THREAD_ID\"}) { +187. thread { id isResolved } +188. } +189. }" +190. ``` +191. +192. ### Step 9: Wait for CI to run +193. +194. The push triggers CI/CD. Use the same approach as `shepherd-task-from-assignment-to-ready` Steps 5, 6, and 7 to: +195. +196. 1. Wait for workflow runs to complete (`gh pr checks $PR_NUMBER -R $REPO --watch`). +197. 2. Evaluate results (excluding the expected "Block remove-before-merge paths" / "No remove-before-merge directories" failure). +198. 3.

This merges the work to `BASE_BRANCH`. +272. +273. ### Step 23: Close the corresponding issue +274. +275. ```bash +276. gh issue close $TASK_ISSUE -R $REPO +277. ``` +278. +279. ### Step 24: Final status report +280. +281. ``` +282.

The documentation should frame this as a safety mechanism rather than a documented feature. + +5. **Comment 3508555532** (ParamSchema.java:61): PR claims these are consumed by ToolDefinition.from* overloads but they're not used in this PR. + - **Merit: No strong merit.** This is intentional—Phase 4.3 extracts the internals while Phase 4.2 handles the wiring later.

Here's what I changed to prevent the first issue from recurring: + +Root cause: The polling only searched PR titles and branch names for the issue number ( 1876 ). Copilot named the PR "feat(java): implement ParamSchema + ParamCoercion..." with branch  copilot/edburns1810-java-tool-ergonomics-tool-as-lambda-im  — neither contained  1876 . + +Fix (3 strategies, tried each iteration): + +1. Issue timeline API — queries GitHub's timeline for cross-referenced PRs (most reliable since "Fixes #1876" creates a link) +2. PR body search — searches open PR bodies for  #1876  +3. Title/branch regex — original fallback + +Also bumped the timeout from 10→15 minutes since Copilot can take that long. + +Would you like to discuss the second stuck point (Phase 1→Phase 2 transition) as well? + +### 16:12 Prompt + +Not just yet. Regarding the "find the linked PR" aspect, does the skill have a backup step that searches for the text "Copilot linked a pull request that will close this issue"? Because that text seems to always appear when Copilot creates the linked PR. + +### 16:14 Response + +Good question. My Strategy A (issue timeline API) is the programmatic equivalent of that — when Copilot links a PR via "Fixes #1876", it creates a  cross-referenced  event in the timeline. However, there's a more direct approach too. + +Let me check if there's a simpler way to get linked PRs: + +Shell Check timeline events for issue 1876 2 lines… +# Let's see what the timeline actually looks like for issue 1876 gh api "/repos/github/copilot-sdk/issues/1876/tim… + +Yes — the  cross-referenced  event is exactly what "Copilot linked a pull request that will close this issue" corresponds to in the API. My Strategy A already queries this. But let me also check if there's a comment-based signal: + +Shell Check issue comments for linked PR text 1 line… +# Check if there's also a comment with that text gh api "/repos/github/copilot-sdk/issues/1876/comments" --jq '.[]… + +No comments — it's only in the timeline events, not the comments API. So Strategy A already covers this via the  cross-referenced  event with actor  Copilot . That's the API representation of the "Copilot linked a pull request that will close this issue" text you see in the UI. + +The skill is already correct. The problem in our run was that Strategy A didn't exist yet — we were only using the title/branch regex (old Strategy C). With the updated skill, the timeline query would have found PR #1877 immediately once Copilot linked it. + +Want me to add an explicit note in the skill mentioning this UI text ↔ API mapping for clarity? + +### 16:14 Prompt + +No. Now on to the second pause. + +I wonder if it would be better to implement `copilot-sdk/.github/skills/shepherd-task/SKILL.md` as a shell script that manually invokes `copilot --yolo` with the Phase 1 and Phase 2 prompts individually? + +In this way we can avoid having the "/compact" step because there would be separate copilot instances. + +If we did that, what is the most deterministic way for the invoking shell script to know the "exit code" like status of `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md`? + +### 16:19 Response + +Asked user I see two main approaches for detecting Phase 1's exit status from the shell script: 1. **Check PR sta… +└ User selected: Option 1: Shell script verifies PR state with gh CLI after copilot exits (Recommended) + +Good choice. Here's the design: + +The shell script would: + +1. Launch  copilot --yolo  with Phase 1 prompt → let it run to completion +2. After exit, verify Phase 1 success by checking: +• An open PR exists linked to the issue (using the multi-strategy search) +• PR targets the correct base branch +• All CI checks pass (excluding "No remove-before-merge directories") +• No unresolved review comments from bots +3. If verified → extract  PR_NUMBER  → launch  copilot --yolo  with Phase 2 prompt +4. After Phase 2 exits, verify the PR was merged to the base branch + +This means the shell script is the source of truth for state transitions — copilot sessions are "fire and forget" workers, and the script does the verification. + +Shall I implement this as a shell script now? + +### 16:20 Prompt + + Yes, write it twice. 1st as a PowerShell script, then as a bash script.

Created  .github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md  — a reusable sub-skill that takes  REPO ,  JTBDTASK_BRANCH , and  PR_NUMBER , approves pending runs via  gh run rerun , and waits for completion via  gh pr checks --watch . +2. Modified  .github/skills/shepherd-task-from-assignment-to-ready/SKILL.md  — replaced the inline Steps 4 and 5 with a reference to invoke the new sub-skill. + +The iteration loop in Step 7.5 ("Return to Step 4") still works since the combined "Steps 4–5" heading replaces the original steps in the same logical position. + + +### 19:14 Prompt + + +Commit and push. + +### 19:16 Prompt + +What happens when someone invokes `copilot-sdk/.github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md` but there are no workflows pending?

Step 1 —  PENDING_RUNS  would be empty, so the  for  loop simply doesn't execute (no-op). +2. Step 2 —  gh pr checks --watch  reports the current state of checks. If they're already complete (or there are none pending), it returns immediately with success. + +The "Error handling" section also explicitly states: "No pending runs found: This is not an error — it means runs were already approved (possibly manually). Proceed directly to waiting for completion." + +So the skill is safe to call idempotently even when there's nothing to approve. + +### 19:18 Prompt + +Now that we have `copilot-sdk/.github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md` as an invocable skill, I want to pepper it in to `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` to address a problem I observed where there were pending workflows that I did not expect to be there. + +Insert a call to `copilot-sdk/.github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md` before steps 5, 10 and 18 in `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md`. + +Renumber the steps in `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` accordingly. + +### 19:23 Response + +Now I'll make the edits.

- -Candidates: - -* Overloads with an options object. -* Fluent builder wrapping `ToolDefinition.from(...)`. - -**Recommendation:** options object first, to avoid overload explosion. - -**Resolution:** - -Use fluent immutable modifier methods on `ToolDefinition` rather than introducing a separate options object in v1. - -Because `ToolDefinition` is already an immutable record carrying `overridesBuiltInTool`, `skipPermission`, and `defer`, the lambda-based `from*` factories should return a `ToolDefinition` that callers may further customize with copy-style fluent methods. - -Example: - -```java -ToolDefinition tool = ToolDefinition.from( - "report_intent", - "Reports the agent's current intent", - Param.of(String.class, "intent", "The intent to report"), - intent -> "Reported intent: " + intent) - .overridesBuiltInTool(true) - .skipPermission(true) - .defer(ToolDefer.AUTO); -``` - -Equivalent context-aware example: - -``` -ToolDefinition tool = ToolDefinition.fromWithToolInvocation( - "report_phase", - "Reports the current phase with invocation context", - Param.of(String.class, "phase", "The current phase"), - (phase, invocation) -> "phase=" + phase + ", toolCallId=" + invocation.getToolCallId()) - .skipPermission(true) - .defer(ToolDefer.NEVER); -``` - -The modifier surface for v1 is: - -``` -ToolDefinition overridesBuiltInTool(boolean value); -ToolDefinition skipPermission(boolean value); -ToolDefinition defer(ToolDefer value); -``` - -Notes: - -- `defer` should use the existing `ToolDefer` enum, not a boolean. -- This keeps the API aligned with the existing `ToolDefinition` data model. -- This avoids introducing a separate options type solely for inline/lambda-defined tools. -- Existing low-level factories (`createOverride`, `createSkipPermission`, `createWithDefer`) may remain for compatibility, but the new lambda-based API should prefer the fluent style. - -### 3.7 — Error model and validation boundaries - -**Question:** Which invalid states should fail early?

- -Unknowns: - -* whether to place new functional interfaces and param DSL under `rpc` or `tool` -* impact on `module-info.java` exports - -**Recommendation:** place user-facing ergonomics in the package users already discover for tools, and keep internal helpers package-private. - -**Resolution:** - -- new public helper types like `Param` belong in `com.github.copilot.tool` -- any necessary `module-info.java` export updates should expose only that user-facing package surface -- no extra public internal-helper types should leak just to support lambda tools - - -### 3.9 — E2E test scenario and snapshot reuse - -**Question:** Do we need a new replay snapshot?

Isn't this the most idiomatic way? - -### 14:44 Response - -You’re right— Supplier  is the most idiomatic Java choice for sync zero-arg handlers. - -You’d avoid it only if you want consistency with a custom tool-function family ( ToolFn0 ,  ToolFn1 , ...), or if you need behavior  Supplier  can’t express cleanly (for example checked exceptions, unless you wrap them, or a separate async SAM instead of  Supplier> ). - -So the practical recommendation is: - -• Use  Supplier  for sync zero-arg overload. -• Use a dedicated async SAM for async zero-arg overload (clearer than  Supplier> ). - -### 14:44 Prompt - -Why is this tools-as-lambda tending to bifurcate into a dual "one for async, another for non-async" pattern? - -### 14:45 Response - -Because Java’s type system doesn’t give a clean single-SAM shape that is both ergonomic and unambiguous for: - -•  R  -•  CompletableFuture  - -If you try one overload, you usually end up with awkward signatures ( Supplier ,  Function<..., ?> ) and runtime branching on return type, or ambiguous lambda inference. - -So APIs split into sync + async mostly for clarity and type inference: - -• sync: simple lambda, returns  R  -• async: simple lambda, returns  CompletableFuture  - -It’s less about architecture and more about making call sites readable and compile-time-safe. - -### 14:45 Prompt - -Pardon my ignorance, but I am unfamiliar with this usage of the acronym SAM.

For zero-arg async, it should be one of: - -ToolDefinition.fromAsync(String name, String description, Supplier> handler) - -or (clearer API surface): - -ToolDefinition.fromAsync(String name, String description, AsyncSupplier handler) -// interface AsyncSupplier { CompletableFuture get(); } - -So  fromAsync(..., Supplier)  only works if callers pass  R = CompletableFuture , which is less explicit and easier to misuse. - - -### 14:53 Prompt - - -Where are you getting this `AsyncSupplier`?

Arity cap for v1 (`1..3` vs `1..5`). - -What does this even mean? - -### 14:20 Response - -It means: - -How many distinct lambda overloads do we ship in v1 before we stop? - -Because Java has no variadic typed function family in the JDK, each arity needs its own SAM/overload family. - -Example: - -• arity 1:  Function  -• arity 2: custom  BiToolFunction  or similar -• arity 3: custom tri-arg SAM -• arity 4+: more custom SAMs - -So  1..3  means support 1-, 2-, and 3-argument tools in v1. - 1..5  means go up through 5 arguments. - -It’s really a scope/control question: where do we stop adding overload families initially? - -### 14:20 Prompt - -Let's go back to C#. How does our C# API handle the arity? - -### 14:21 Response - -C# does not impose an explicit arity cap in our API. - -It takes a single  Delegate : - -public static AIFunction DefineTool( - Delegate method, - CopilotToolOptions? toolOptions = null, - AIFunctionFactoryOptions? factoryOptions = null) - -and then hands that delegate to: - -AIFunctionFactory.Create(method, factoryOptions) - -See  dotnet/src/CopilotTool.cs:36-49 . - -So arity is handled by delegate reflection, not by overload families: - -• zero-arg method:  ReturnsOk  -• one-arg lambda:  (string value) => value  - -C# can therefore accept many arities through one entry point. Java can’t match that cleanly with JDK SAMs, hence the arity-cap question for Java. - -### 14:21 Prompt - -So this is just a core language difference between C# and Java? - -### 14:22 Response - -Yes — mostly a core language/runtime difference. - -C# gives you: - -• a universal  Delegate  abstraction -• rich reflection over delegate signatures -• natural sync/async and multi-arity expression through  Func<> / Action<>  - -Java gives you: - -• individual SAM types, not one universal callable type -• no built-in  Function3 ,  Function4 , etc. -• weaker lambda introspection for metadata/signature recovery - -So C# can unify arities behind one  DefineTool(Delegate ...) . -Java usually has to choose between: - -• explicit overload/SAM families, or -• a lower-level reflective/invocation-based API. - -### 14:23 Prompt - -Ok, so let's go with 1..3. Show me what the `from` overloads would look like for that. And do we need sync and async versions? - - -### 14:25 Response - -Yes, I’d do both sync and async. - -``` -// 0 args -static ToolDefinition from( - String name, String description, Supplier handler); - -static ToolDefinition fromAsync( - String name, String description, Supplier> handler); - -// 1 arg -static ToolDefinition from( - String name, String description, Param p1, Function handler); - -static ToolDefinition fromAsync( - String name, String description, Param p1, AsyncFunction1 handler); - -// 2 args -static ToolDefinition from( - String name, String description, Param p1, Param p2, BiFunction handler); - -static ToolDefinition fromAsync( - String name, String description, Param p1, Param p2, AsyncFunction2 handler); - -// 3 args -static ToolDefinition from( - String name, String description, Param p1, Param p2, Param p3, TriFunction handler); - -static ToolDefinition fromAsync( - String name, String description, Param p1, Param p2, Param p3, AsyncFunction3 handler); - - TriFunction  and  AsyncFunction{1,2,3}  would be custom SAMs. -``` - -### 14:25 Prompt - -This is starting to smell a bit off. I don't like inventing new types for fundamental things like function calling. I want to stick with JDK classes. - -If we limited ourselves to 1..2-arity, and used `Function` and `BiFunction` for the sync case for 1 and 2 arg, then is there something analogous to what we did with the zero-arg async, but for the 1 and 2 arg async case? - -``` -ToolDefinition.fromAsync(String name, String description, Supplier> handler) -``` - -### 15:14 Response - -Yes. If you want JDK-only types and cap at 1..2 arity, the direct async analog is: - -``` -// 0 args -static ToolDefinition fromAsync( - String name, - String description, - Supplier> handler); - -// 1 arg -static ToolDefinition fromAsync( - String name, - String description, - Param p1, - Function> handler); - -// 2 args -static ToolDefinition fromAsync( - String name, - String description, - Param p1, - Param p2, - BiFunction> handler); -``` - -So yes — same pattern as zero-arg async: the handler returns  CompletableFuture , and you don’t need any custom SAM types. - -### 15:14 Prompt - -Please show me usage examples with lambdas for the sync and async 0..2 arg variants of `ToolDefinition.from*`. - -### 15:15 Response - -``` -import java.util.List; -import java.util.concurrent.CompletableFuture; -import java.util.function.BiFunction; -import java.util.function.Function; -import java.util.function.Supplier; - -// Assume Param.of(name, description, type) exists in your API. -Param cityParam = Param.of("city", "City to query", String.class); -Param qParam = Param.of("query", "Search query", String.class); -Param limitParam = Param.of("limit", "Max results", Integer.class); - -// ----------------------------- -// Sync variants (from) -// ----------------------------- - -ToolDefinition pingSync = ToolDefinition.from( - "ping", - "Health check", - () -> "ok" -); - -ToolDefinition weatherSync = ToolDefinition.from( - "weather", - "Get weather by city", - cityParam, - city -> "Sunny in " + city -); - -ToolDefinition searchSync = ToolDefinition.from( - "search", - "Search with limit", - qParam, - limitParam, - (query, limit) -> "Top " + limit + " results for " + query -); - -// ----------------------------- -// Async variants (fromAsync) -// ----------------------------- - -ToolDefinition pingAsync = ToolDefinition.fromAsync( - "ping_async", - "Async health check", - () -> CompletableFuture.completedFuture("ok") -); - -ToolDefinition weatherAsync = ToolDefinition.fromAsync( - "weather_async", - "Async weather by city", - cityParam, - city -> CompletableFuture.supplyAsync(() -> "Sunny in " + city) -); - -ToolDefinition searchAsync = ToolDefinition.fromAsync( - "search_async", - "Async search with limit", - qParam, - limitParam, - (query, limit) -> CompletableFuture.supplyAsync( - () -> "Top " + limit + " results for " + query - ) -); - -List tools = List.of( - pingSync, weatherSync, searchSync, - pingAsync, weatherAsync, searchAsync -); -``` - -### 15:15 Prompt - -Please pepper in comments for the 0 arg, 1 arg, 2 arg, for ease of reading. - -### 15:16 Response - -``` -import java.util.List; -import java.util.concurrent.CompletableFuture; - -// Assume Param.of(name, description, type) exists in your API. -Param cityParam = Param.of("city", "City to query", String.class); -Param qParam = Param.of("query", "Search query", String.class); -Param limitParam = Param.of("limit", "Max results", Integer.class); - -// ----------------------------- -// Sync variants (from) -// ----------------------------- - -// 0-arg sync tool: Supplier -ToolDefinition pingSync = ToolDefinition.from( - "ping", - "Health check", - () -> "ok" -); - -// 1-arg sync tool: Function -ToolDefinition weatherSync = ToolDefinition.from( - "weather", - "Get weather by city", - cityParam, - city -> "Sunny in " + city -); - -// 2-arg sync tool: BiFunction -ToolDefinition searchSync = ToolDefinition.from( - "search", - "Search with limit", - qParam, - limitParam, - (query, limit) -> "Top " + limit + " results for " + query -); - -// ----------------------------- -// Async variants (fromAsync) -// ----------------------------- - -// 0-arg async tool: Supplier> -ToolDefinition pingAsync = ToolDefinition.fromAsync( - "ping_async", - "Async health check", - () -> CompletableFuture.completedFuture("ok") -); - -// 1-arg async tool: Function> -ToolDefinition weatherAsync = ToolDefinition.fromAsync( - "weather_async", - "Async weather by city", - cityParam, - city -> CompletableFuture.supplyAsync(() -> "Sunny in " + city) -); - -// 2-arg async tool: BiFunction> -ToolDefinition searchAsync = ToolDefinition.fromAsync( - "search_async", - "Async search with limit", - qParam, - limitParam, - (query, limit) -> CompletableFuture.supplyAsync( - () -> "Top " + limit + " results for " + query - ) -); - -List tools = List.of( - pingSync, weatherSync, searchSync, - pingAsync, weatherAsync, searchAsync -); -``` - -### 15:18 Prompt - -This is starting to look better. Here is our existing `Param`; `copilot-sdk/java/src/main/java/com/github/copilot/tool/Param.java`.

Could we then use `Param` for both lambda and annotation cases? - - -Now, is there any way we can minimize it even further leveraging type inference? - -### 15:25 Response - -No — that specific design won’t work in Java. - - @interface  types cannot extend a class (or declare  extends  at all), so an annotation like  @CopilotParam  cannot inherit from a non-annotation  Param  type. Annotations are a separate language construct with fixed rules. - -The practical pattern is: - -• keep annotation metadata in  @Param  (or  @CopilotParam  if you rename), and -• add a separate runtime metadata type for lambda tools (for example  ParamSpec  with  ParamSpec.of(...) ), -• then normalize both into one internal model. - -### 15:28 Prompt - -Let's assume I rename `Param` to `CopilotToolParam`. - -Show me the `Param` that fits your usage with the fluent api.

Evaluating the design we currently elicited, how does that answer the three unknowns for 3.3? - -### 16:34 Prompt - - Params.of(...)  helps, but it does not by itself answer all three unknowns. It mainly answers ordering/composition. - -I’d say the current elicited design answers 3.3 like this: - -• 1. Defaults representation and validation by type - Params.of(...)  only works cleanly if each  Param  carries a type token (for example  Param  or  Class ). Then  defaultValue  can mirror the annotation API and be validated against that type. -• 2. Optionality vs. default values -Reuse the current annotation rule: -•  required=true  by default -• non-empty default means effectively optional -• reject  required=true  + defaultValue present -• 3. Whether descriptions are required by policy - Params.of(...)  does not settle that. Policy is separate. My recommendation: keep descriptions allowed-but-not-forced in API, and enforce stricter quality later if desired. - -So:  Params.of(...)  is a good container, but typed  Param  is the real key. - -### 16:34 Prompt - -So what would `Params` look like with typed Param? - -### 16:35 Response - -``` -Something like this: - -package com.github.copilot.tool; - -import java.util.List; - -public final class Params { - - private final List> values; - - private Params(List> values) { - this.values = List.copyOf(values); - } - - public static Params of(Param... values) { - return new Params(List.of(values)); - } - - public List> values() { - return values; - } -} - -And typed  Param : - -package com.github.copilot.tool; - -public final class Param { - - private final Class type; - private final String name; - private final String value; - private final boolean required; - private final String defaultValue; - - private Param(Class type, String name, String value, boolean required, String defaultValue) { - this.type = type; - this.name = name; - this.value = value; - this.required = required; - this.defaultValue = defaultValue; - } - - public static Param of(Class type, String name, String value) { - return new Param<>(type, name, value, true, ""); - } - - public Param required(boolean required) { - return new Param<>(type, name, value, required, defaultValue); - } - - public Param defaultValue(String defaultValue) { - return new Param<>(type, name, value, false, defaultValue); - } - - public Class type() { return type; } - public String name() { return name; } - public String value() { return value; } - public boolean required() { return required; } - public String defaultValue() { return defaultValue; } -} -``` - -Usage: - -``` -Params params = Params.of( - Param.of(String.class, "query", "Search query"), - Param.of(Integer.class, "limit", "Max results").defaultValue("10") -); -``` - -That gives ordered, typed parameter metadata. - - -### 16:38 Prompt - -Here is your complete `Param`.

But is there anything else we need to specify in this resolution for 3.7? - -### 17:26 Response - -Yes — I’d make the resolution a bit more explicit about where validation happens and what kind of failure each layer uses. - -Add: - -- Construction-time validation for lambda tools: - - all `ToolDefinition.from*` factories must validate before returning - - failures use `IllegalArgumentException` - - messages should identify the offending tool name and parameter name when possible -- `Param`-local validation: - - blank name/description - - `required=true` with default - - default incompatible with declared type -- Cross-parameter validation: - - duplicate parameter names - - unsupported schema/type mappings - - invalid ToolInvocation-specific combinations, if that lane is included - -So 3.7 should resolve not just what fails early, but which layer owns each validation. - -### 17:28 Prompt - -You stated - ------ - - - invalid ToolInvocation-specific combinations, if that lane is included - - - ----- - -Give me an example of such an invalid combination. - -### 17:29 Response - -A good example is using the wrong factory family for a context-aware lambda. - -For example, this should be invalid: - -ToolDefinition.from( - "report_phase", - "Reports the current phase", - Param.of(String.class, "phase", "The current phase"), - (phase, invocation) -> "phase=" + phase -); - -Why invalid: - -•  from(...)  is the non-ToolInvocation family -• a two-parameter lambda here would mean “2 visible tool params,” not “1 visible param + hidden invocation” - -So if  ToolInvocation  support exists, it should only be legal through: - -ToolDefinition.fromWithToolInvocation(...) -ToolDefinition.fromAsyncWithToolInvocation(...) - -That separation is itself part of the validation story. - -### 17:29 Prompt - -But how would one guard against such an invalid invocation? - -### 17:30 Response - -Mostly by the type system, not runtime checks. - -Example: - -ToolDefinition.from( - "report_phase", - "Reports the current phase", - Param.of(String.class, "phase", "The current phase"), - (phase, invocation) -> ... -); - -If  from(...)  is declared to take: - -Param, Function - -then a two-argument lambda simply does not compile. - -Likewise, only  fromWithToolInvocation(...)  would accept: - -BiFunction - -So the main guard is: - -• distinct method families -• strongly typed JDK SAM parameters -• compile-time mismatch - -Runtime validation is only needed for metadata/state checks, not this misuse. - -### 17:30 Prompt - -So it seems we can remove this from the 3.7 resolution: - ------ - - - invalid ToolInvocation-specific combinations, if that lane is included - - ----- - -No? - -### 17:31 Response - -Yes, I agree. - -For the lambda API shape we’ve converged on, that item does not belong in 3.7, because those misuses are prevented at compile time by overload typing, not by runtime validation. - -So 3.7 should stay focused on true runtime/construction-time invalid states such as: - -• duplicate parameter names -• missing/blank metadata -• unsupported type mappings -• incompatible default values - - -### 17:32 Prompt - - -On to 3.8. - -You said: - ------ - -**Question:** Where do new public types live without destabilizing existing API? - -Unknowns: - -* whether to place new functional interfaces and param DSL under `rpc` or `tool` -* impact on `module-info.java` exports - -**Recommendation:** place user-facing ergonomics in the package users already discover for tools, and keep internal helpers package-private. - - ----- - -I thought we already agreed `package com.github.copilot.tool`? - -As for as the `module-info.java` the common sense thing is what you recommended. - -What are we missing? - -### 17:34 Response - -You’re right: 3.8 is basically resolved now. - -What changed since that earlier wording: - -• we dropped custom functional interfaces -• we settled on  com.github.copilot.tool  for the new public ergonomics types -• only  ToolDefinition  remains in  com.github.copilot.rpc  - -So the only thing left to state in the resolution is: - -• new public helper types like  Param  belong in  com.github.copilot.tool  -• any necessary  module-info.java  export updates should expose only that user-facing package surface -• no extra public internal-helper types should leak just to support lambda tools - -So we’re not really missing a design decision anymore; we just need to record it cleanly. - -### 17:41 Prompt - -I have updated `copilot-sdk/1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge/1810-ignorance-reduction-for-implementation-plan.md` with all the Phase 3 **Resolutions:** we elicited. Please review it and see if I missed anything. - -### 17:44 Response - -I see several gaps and issues: - -3.1 has two problems: - -DONE • Contains the old, unvalidated version of  Param  followed by the final version — the first block should be removed, it's stale. -DONE • The complete  from / fromAsync  0..2 arity signatures are never explicitly listed — only usage examples appear. The plan should have the method signatures as the canonical API surface. -DONE • The usage example at line 391 still uses the old untyped form:  Param.of("phase", "Current phase")  instead of  Param.of(String.class, "phase", "Current phase") . - -DONE 3.2 — the resolution reads like an instruction, not a decision. It should say: "v1 uses only JDK functional interfaces; sync and async are separated by method-family naming ( from / fromAsync / fromWithToolInvocation / fromAsyncWithToolInvocation ); no custom SAMs required." - -3.3 — two things missing: - -DONE •  Params.of(...)  decision: not needed for v1 (per our conversation) — should be explicitly recorded. -DONE • Annotation API alignment note:  @CopilotTool  processing should eventually enforce non-empty  @Param.value()  at compile time. Filed issue 1836. - -DONE 4.1 — says  com.github.copilot.rpc/  but we decided new types go in  com.github.copilot.tool . - -DONE 4.3 — says  ParamDef  on line 673, but the design uses  Param . - -### 17:48 Prompt - -You stated - ------- - -• The complete  from / fromAsync  0..2 arity signatures are never explicitly listed — only usage examples appear.

I am particularly keen to ensure we have good test coverage. - - -### 18:38 Response - -Here's my review: - -──────────────────── - -Overall: solid, correct implementation. The PR cleanly implements `ToolInvocation` injection by: - -1. Filtering it from schema generation -2. Passing `invocation` directly in generated method calls -3. Good compile-time validation (duplicate, `@Param`-annotated) - -Test coverage assessment: - -✅ Well covered: - -- Instance method + ToolInvocation (handler invocation + schema exclusion) -- Static method + ToolInvocation -- Async method + ToolInvocation -- Compile error: duplicate ToolInvocation params -- Compile error: `@Param` on ToolInvocation -- Processor-level tests verify generated code shape - -⚠️ Gaps I'd flag: - -1. Zero visible args + ToolInvocation only. No test covers: - -``` -@CopilotTool("...") -public String onlyInvocation(ToolInvocation invocation) { ... } -``` - -This exercises the `schemaParameters.isEmpty()` path with a non-empty `params` list. - -2. `ToolInvocation` as FIRST parameter. All fixtures put it last. Add a test with: - -``` -@CopilotTool("...") -public String invertedOrder(ToolInvocation invocation, @Param("Phase") String phase) { ... } -``` - -The `generateArgList` iterates over *all* params (not just schema params), so position matters. - -3. Single-record + ToolInvocation. What happens with: - -``` -@CopilotTool("...") -public String withRecord(SearchArgs args, ToolInvocation invocation) { ... } -``` - -The `schemaParameters.size() == 1 && isRecord(...)` path would activate — does the generated code correctly pass both? - -4. Test coverage for position independence. - - 1. Add Javadoc to the `ToolInvocation` class (or to `@CopilotTool` annotation Javadoc) stating that `ToolInvocation` may appear at any position in the parameter list and is always excluded from the tool schema regardless of position. - - 2. Update the Java README `ToolInvocation` section to mention that position does not matter — it can appear before, between, or after `@Param`-annotated parameters. - - 3. Add tests proving position independence: - - - `ToolInvocation` as the first parameter: - - ``` - @CopilotTool("...") - public String report(ToolInvocation invocation, @Param("Phase") String phase) { ... } - ``` - - - `ToolInvocation` as the only parameter (zero visible args): - - ``` - @CopilotTool("...") - public String onlyContext(ToolInvocation invocation) { ... } - ``` - - - `ToolInvocation` in the middle of two visible params: - - ``` - @CopilotTool("...") - public String report(@Param("Phase") String phase, ToolInvocation invocation, @Param("Limit") int limit) { ... } - ``` - - Each test should verify both that the schema excludes `ToolInvocation` and that the handler receives the correct invocation context. - -Minor correctness concern: - -In `generateLambdaBody`, when `schemaParameters` is non-empty, the code extracts args from the map. But `generateArgList` is called with the full `params` list (not `schemaParameters`). This is correct! But the variable extraction loop only iterates `schemaParameters`, so ToolInvocation params won't have a local variable declared — they get `invocation` directly in the call. This works because the lambda parameter is named `invocation`. ✅ - -Verdict: Merge-ready with the caveat that adding test cases for gaps #1–3 above would strengthen confidence. Gap #2 (invocation-first position) is the most important to verify works correctly. - -### 18:42 Prompt - -What's this "position-independence" thing? - -### 18:47 Response - -I mean: can  ToolInvocation  appear anywhere in the parameter list — first, middle, or last — and still work? - -// Last (all fixtures use this) -public String report(@Param("Phase") String phase, ToolInvocation invocation) - -// First -public String report(ToolInvocation invocation, @Param("Phase") String phase) - -// Middle (if 2+ visible args) -public String report(@Param("Phase") String phase, ToolInvocation invocation, @Param("Limit") int limit) - -Looking at the implementation,  generateArgList  iterates over all params in declaration order and emits  invocation  for ToolInvocation-typed ones and the extracted variable name for others. So yes, position should not matter — it should be position-independent. - -But there's no test proving it. All fixtures put ToolInvocation last. That's why I flagged gap #2. - -### 18:48 Prompt? - -Does the specification call for position independence? - -### 18:49 Response - -Looking back at the issue spec (#1831), it says: - -If a `@CopilotTool` method declares a parameter of type `com.github.copilot.rpc.ToolInvocation`, the annotation processor must: -• exclude that parameter from generated JSON Schema -• pass the current `invocation` object directly when generating the method call - -It does not specify position requirements or constraints. It doesn't say "must be last" nor does it say "can be anywhere." - -So: the spec is silent on position. The implementation happens to support any position, but there's no explicit requirement either way. - -### 18:50 Prompt - -Given that the implementation supports it, we must document it. We must document it in the javadoc, not just in the README. - -I am working your comments into a review response. Give me the text to require the agent to document the position independence in the normative Javadoc and the java README. Also to create tests proving the correctness of the position independence. - -### 18:52 Prompt - -Position independence of `ToolInvocation` parameter - -The implementation correctly supports `ToolInvocation` at any position in the method signature — first, middle, or last. However, this behavior is undocumented and untested. - -Please: - -1. Add Javadoc to the `ToolInvocation` class (or to `@CopilotTool` annotation Javadoc) stating that `ToolInvocation` may appear at any position in the parameter list and is always excluded from the tool schema regardless of position. - -2. Update the Java README `ToolInvocation` section to mention that position does not matter — it can appear before, between, or after `@Param`-annotated parameters. - -3. Add tests proving position independence: - - - `ToolInvocation` as the first parameter: - - ``` - @CopilotTool("...") - public String report(ToolInvocation invocation, @Param("Phase") String phase) { ... } - ``` - - - `ToolInvocation` as the only parameter (zero visible args): - - ``` - @CopilotTool("...") - public String onlyContext(ToolInvocation invocation) { ... } - ``` - - - `ToolInvocation` in the middle of two visible params: - - ``` - @CopilotTool("...") - public String report(@Param("Phase") String phase, ToolInvocation invocation, @Param("Limit") int limit) { ... } - ``` - - Each test should verify both that the schema excludes `ToolInvocation` and that the handler receives the correct invocation context. - -### 19:24 Prompt - -While working on Feature #1810, we had cause to request the global-search-and-replace renaming of the class `./src/main/java/com/github/copilot/tool/Param.java` to be `CopilotToolParam` instead. - -The reason is that I want to use `Param` for the `tool-as-lambda` variant of the API.

The working prompts for this work are being kept in the directory `copilot-sdk/1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge/` on topic branch `upstream/edburns/1810-java-tool-ergonomics-tool-as-lambda`. The work to implement the following steps is largely recorded in these prompt files. - -1. The **Feature** work item https://github.com/github/copilot-sdk/issues/1810 is the container for all the child work items of type **Task**. The issue types are important. - -2. I created child task https://github.com/github/copilot-sdk/issues/1811 . This resulted in the initial creation of `copilot-sdk/1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge/1810-ignorance-reduction-for-implementation-plan.md`. I resolved the task. - -3. I created child task https://github.com/github/copilot-sdk/issues/1816 , performed the actions to fill in **Resolution** sections for each of the sub-sections in Phase 3. I resolved the task. - -4. I created child task https://github.com/github/copilot-sdk/issues/1817 to ask the LLM to create further child tasks for the subsections in Phase 4 of the plan. - -5. As an aside, I had to do a separete workflow due to a renaming issue that emerged while I was working on #1816. This is task https://github.com/github/copilot-sdk/issues/1837 . - -### Job to be done - -I want to have a skill that: - -- assumes the setup like we have created above -- which I can pass one of the sub-tasks created during #1817. For disscussion the passed sub-task is `jtbdtask`. -- shepherds the work through the following actions. - -This skill will be run in a `copilot --yolo` session on my Dev Box. It will run as me. The skill will: - -1. Assign the `jtbdtask` to `@Copilot`. -2. This action causes the following to happen. - - 1. `@Copilot` creates its own topic branch from the base branch `upstream/edburns/1810-java-tool-ergonomics-tool-as-lambda` and starts iterating there. For discssion this branch is is `jtbdtask-branch`. It creates a PR with that topic branch. For discussion this is `jtbdtask-pr`. - - 2. It does some initial work and creates pushes some commits to `jtbdtask-branch`. - -4. This causes an **Approve workflows to run** button to appear in the `jtbdtask-pr`. -5. The skill uses `gh` to effectively select that **Approve workflows to run** button, starting the workflows. -6. The skill waits for the workflows to complete running and evaluates the result. -7. Substeps: - 1. If there are promlems, the skill asks `@Copilot` to fix the problems. The skill is very specific in telling what `@Copilot` must do to fix the problems. The manner in which the skill asks `@Copilot` is the `gh` analog to: - 1. a human visiting the `jtbdtask-pr` in the GitHub web UI. - 2. selecting the **Submit review** button - 3. Filling in the comment and at mentioning `@Copilot`. - 4. Selecting **Request changes**. - 5. Go back to step 4. - 2. If there are no problems, proceed. -8. Address any pre **Ready for review** problems. Sometimes there are review agents that leave comments on the `jtbdtask-pr` even before requesting review by selecting the **Ready for review** button. Addressing the pre **Ready for review** problems requires iterating in the same way as in step 7. - -### 13:33 Response - -Thought for 10s -The user wants to create a per-repository skill that automates the process of shepherding a child task from "assigned to Copilot" through to "Ready for review".

These runs are from the same repository (not a fork), so that API doesn't apply.

The runs show `conclusion: "action_required"` and `status: "completed"`. This is odd — typically `action_required` means they're waiting. Let me look at the actual run details to understand what's happening. -Actually wait - looking more carefully, the status is "completed" with conclusion "action_required". -This looks like GitHub Actions' waiting-for-approval state, likely tied to environment protection rules or deployment protection settings rather than the fork PR approval endpoint.

This is expected. - -I observe the PR created by the skill, #1857, targeted `main` instead of the specified base branch. - -Update the skill to make it so when the PR is assigned to `@Copilot`, the base branch `BASE_BRANCH` is set as the branch to use by the PR. - -### 15:40 Response - -Done. Three updates committed and pushed: - -1.  gh run rerun  — replaced the fork-only  POST .../approve  API with  gh run rerun  -2. Ignore "Block remove-before-merge paths" — noted as expected failure, excluded from evaluation -3.

Create a topic branch from `$BASE_BRANCH`. -2. Open a draft PR targeting `$BASE_BRANCH`. -3. Push initial commits. - -**Important:** After the PR is created, verify it targets `$BASE_BRANCH`. Copilot sometimes targets `main` instead. If the PR base is wrong, fix it: - -```bash -gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" -``` - - ------ - -Check if the act of specifying the `--base` can be done in the same `edit` command that has the `--add-assignee`. If so, this step can be simplified dramatically. - -### 15:43 Response - - -No  --base  flag on  gh issue edit  — that's a PR-only option. So the base branch can't be set at assignment time; it has to be corrected after the PR is created (Step 2), as currently written. - -The two-step approach (assign → then fix base on the PR) is the simplest available path. - -### 15:43 Prompt - -But isn't there a timing issue? - -### 15:44 Response - -Yes — there's a race condition. Copilot starts working immediately after assignment. If it pushes commits targeting  main  before we fix the base branch, those commits are based on the wrong branch. Changing the base after the fact with  gh pr edit --base  only changes the PR's merge target, it doesn't rebase the commits. - -This means Copilot's code changes may not account for work already on  $BASE_BRANCH , leading to conflicts or missing context. - -Asked user How should we handle this?

A better name is `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md`. Please rename the skill and commit and push. - -## from "mark as ready for review" to "merged to specified base branch" - -Now it is time to make another skill for shepherding the task from "mark as ready to review" to "merged to the specified base branch". This skill must be written to `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md`. This skill will take the same inputs as the previous one. - -This skill is a follow up skill. It is intended to be run after `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md`. - -We will continue to use the terms defined when authoring the previous skill. - -1. Mark `jtbdtask-pr` as **Ready to review**. -2. This causes the copilot code review agent to review the code. The code review causes yet more comments on `jtbdtask-pr`. -3. You must wait for the copilot code review agent to complete its review work and post the findings to `jtbdtask-pr` before proceeding. -4. It is important to identify the batch of review findings that correspond to the action in step 2. For discussion this is `jtbdtask-pr-comments`. Here is some sample text that leads off such a batch, using pseudo-XML syntax to enclose the text. This was from PR https://github.com/github/copilot-sdk/pull/1763 , which was a semi-agentic implementation of what we're trying to automate in this skill. - - - ## Copilot's findings - - - **Files reviewed:** 5/5 changed files - - **Comments generated:** 5 - - - Search for similar text to identify `jtbdtask-pr-comments`. - - If there are no comments for this round, skip to step 18. - - When `jtbdtask-pr-comments` has been identified, you know the copilot code review agent has completed its work. -5. Once you have identified `jtbdtask-pr-comments`, know that there will be N individual comments within that `jtbdtask-pr-comments` block. The value of N is in the **Comments generated:** statement. -6. You must address each of the N comments in the `jtbdtask-pr-comments` block locally. Do not push to the topic branch for `jtbdtask-pr` until all the comments have been addressed. -7. The act of addressing the comments is done locally, within the existing `copilot --yolo` session. ❌❌❌This part of the work does not use the remote agent.❌❌❌. -8. Fetch the `upstream` remote. This will cause the topic branch for `jtbdtask-pr` to be added to the local clone. -9. Run `gh api /user --jq '.login'` to get the currently logged in username. For discussion, let this be `gh-current-user`. -10. Use `git worktree add` to create a new worktree for the topic branch, following this pattern. Let's say the number for `jtbdtask-pr` is 9999. Create a worktree called `gh-current-user/review-copilot-pr-9999` checked out to the topic branch for `jtbdtask-pr`. Make sure to substitute the value for `gh-current-user`. For discussion this worktree is called the `jtbdtask-pr-comments-comment-worktree`. -11. Now it's time to work through the comments in `jtbdtask-pr-comments` locally, one by one. When we're done, we'll push to the upstream remote topic branch for `jtbdtask-pr`. -12. For each review comment - - 1. Find the specific review comment in such a way that `gh` can address that individual comment. Coming back to the https://github.com/github/copilot-sdk/pull/1763 example, it will be something like `discussion_r3456155645`. Let this be `jtbdtask-pr-comments-comment`. - - 1. The skill instructs the LLM to do this: - - - Consider `jtbdtask-pr-comments-comment`. Carefully evaluate the comment. Judge the merit of the comment. - - - If there is no merit to the comment, mark the comment as resolved with an explanatory note. - - - If there is merit to the comment, evaluate the suggested remedy. - - - If you agree with the suggested remedy proceed. - - - If you do not agree with the suggested remedy, come up with another remedy and proceed. - - - Implement the remedy for `jtbdtask-pr-comments-comment` in the `jtbdtask-pr-comments-comment-worktree`. Use the appropriate langage coding skill in the `copilot-sdk/.github/skills/` directory to know how to run tests to verify the fix. Whenever possible, only run the tests that are directly related to the fix, in isolation. ❌❌❌DO NOT RUN THE FULL TEST SUITE at this stage.❌❌❌ - - - If the commit has to do with Java, YOU MUST ALWAYS RUN `mvn spotless:apply` in the java directory before each commit. - - - Once you get a clean run of the relevant tests, commit the file, ❌❌❌but do not push❌❌❌. - - - Keep track of the commit hash. You will need it when it comes time to update the corresponding `jtbdtask-pr-comments` comments on `jtbdtask-pr`. - -13. Once you have worked through all N review comments and dealt with them as appropriate, then, and only then, push to the topic branch for PR `jtbdtask-pr` on the upstream. - - 1. For each review comment `jtbdtask-pr-comments-comment`, state what you did to address the comment. If the action corresponds to a commit, state the commit hash such as "Fixed in ". - - 2. Mark `jtbdtask-pr-comments-comment` as resolved. - -14. The act of pushing to the topic branch will again trigger the CI/CD. - -15. Use the knowledge from `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready` step 5, 6 and 7 to get the status of the checks. Do not use any steps after step 7 from this other skill. - - **Note:** Ignore failures from the "Block remove-before-merge paths" / "No remove-before-merge directories" workflow. This failure is expected on feature branches and is not a real problem. - -16. At this point you will have addressed all review comments. Re-request Copilot review by executing this command. - - ``` - gh pr edit -R --add-reviewer "copilot-pull-request-reviewer" - ``` - -17. Go back to step 3. Max iterations 20. - -18. Verify the only failed check is "Block remove-before-merge paths" / "No remove-before-merge directories". - -19. Delete the worktree local `jtbdtask-pr-comments-comment-worktree` and the corresponding locally checked out branch for the `jtbdtask-pr`. - -20. ❌❌❌Ensure the base branch is never `main`❌❌❌ and always the `BASE_BRANCH` from this invocation. - -21. If there are conflicts, - -22. Merge the PR so that the work is merged to `BASE_BRANCH`. - - -### 17:16 Prompt - -After the copilot code review agent has left comments on a PR, and I have addressed all the comments.

What is the `gh` command to re-request review from Copilot? - -``` -gh pr edit -R --add-reviewer "copilot-pull-request-reviewer" -``` - -That's the bot account name for the Copilot code review agent.

Will that work? - -Yes — requesting a reviewer that has already reviewed (or been requested) re-triggers the review.

Orchestrates the full lifecycle of a child **Task** issue from assignment through merge. This skill simply invokes the two phase skills in sequence: -11. -12. 1. `shepherd-task-from-assignment-to-ready` — assigns to Copilot, waits for PR, approves workflows, iterates until CI passes and no review-agent comments remain. -13. 2. `shepherd-task-from-ready-to-merged-to-base` — marks Ready for Review, addresses Copilot code review comments locally, iterates until clean, and merges to the base branch. -14. -15. ## Inputs -16. -17. - `TASK_ISSUE`: The issue number (e.g., `1841`) or URL of the child task to shepherd. -18. - `BASE_BRANCH`: The base branch the task PR should target (e.g., `edburns/1810-java-tool-ergonomics-tool-as-lambda`). -19. - `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). -20. -21. ## Prerequisites -22. -23. - `gh` CLI authenticated with sufficient permissions (issues, PRs, actions, reviews). -24. - The task issue already exists and has a clear description of work to do. -25. - The base branch exists in the repository. -26. -27. --- -28. -29. ## Procedure -30. -31. ### Phase 1: Assignment to Ready for Review -32. -33. Invoke the skill defined in `.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md` with the same inputs: -34. -35. - `TASK_ISSUE`: as provided -36. - `BASE_BRANCH`: as provided -37. - `REPO`: as provided -38. -39. **If Phase 1 fails** (reports `SHEPHERD FAILED`), stop and propagate the failure. Do NOT proceed to Phase 2. -40. -41. **If Phase 1 succeeds** (reports `SHEPHERD COMPLETE`), proceed to Phase 2. -42. -43. ### Phase 2: Ready for Review to Merged -44. -45. Only if Phase 1 completed successfully, invoke the skill defined in `.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` with the same inputs: -46. -47. - `TASK_ISSUE`: as provided -48. - `BASE_BRANCH`: as provided -49. - `REPO`: as provided -50. - `PR_NUMBER`: carried over from Phase 1 (the PR that was created and shepherded) -51. -52. ### Final Status -53. -54. On success: -55. -56. ``` -57. SHEPHERD TASK COMPLETE: Task #$TASK_ISSUE has been fully shepherded. -58. PR merged to $BASE_BRANCH. -59. ``` -60. -61. On failure in either phase: -62. -63. ``` -64. SHEPHERD TASK FAILED: Task #$TASK_ISSUE failed during [Phase 1|Phase 2]. -65. [Error details from the failed phase] -66. ``` -67. -68. --- -69. -70. ## Notes -71. -72. - This skill runs in a `copilot --yolo` session on a Dev Box, executing as the authenticated user. -73. - The `PR_NUMBER` is determined during Phase 1 and passed implicitly to Phase 2. -74. - **Do edit the plan/checklist files** (e.g., `1810-ignorance-reduction-for-implementation-plan.md`) to mark the task as complete. -75. -```` - -

    - -``` -## Pull request overview - -This PR updates the repository’s pinned `@github/copilot` schema dependency and regenerates the protocol-derived types across SDK languages (Java/.NET/Go/Rust/Python/Node) to reflect new/renamed session-limit fields and newly added events/RPC surfaces (e.g., completions, usage checkpoint, session-limits-exhausted UI flow). - -**Changes:** -- Bumped `@github/copilot` from `^1.0.66-2` to `^1.0.66` across Node packages, test harness, and Java codegen/pom tracking property. -- Regenerated session events + RPC API types across languages (rename response limits → session limits; add `session.usage_checkpoint`; add `session_limits_exhausted.*`; add `session.completions.*`; add sandbox-bypass request fields; add adaptive thinking capability; add `reasoningWireField`). -- Updated a few handwritten Java tests/call sites to compile against the regenerated record/type signatures. - -

The actual Phase 4.3 work may need a separate task. - -It looks like the edit made during the execution of skill `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md` step 1 messed up the formatting, which caused the agent to not be able to understand the assignment. - -What do you think about this hypothesis? - -Why do you think the agent messed up? - -### 13:35 Response - -Your hypothesis is correct. Here's what happened: - -1. The bash pattern `$(gh issue view ... --jq '.body')` strips newlines. When you capture multi-line output into a bash variable with `$(...)`, the shell preserves internal newlines — but the LLM executing this in PowerShell (or even in bash without proper quoting) likely flattened the markdown. -2. The resulting single-paragraph wall of text made it impossible for the Copilot cloud agent to parse the structured issue. It couldn't see the headings (`## Overview`, `## Scope / deliverables`, etc.), so it fell back to the simplest interpretation — the dependency bump it noticed was needed. -3. The `INSTRUCTION` separator `--------` was supposed to visually separate the prepended note from the original body, but since the original body was already flattened into one line, the separator appeared mid-paragraph. - -Root cause: The skill's bash snippet doesn't preserve the markdown formatting when doing the prepend. On PowerShell (which is what we actually run), the `$()` capture + string interpolation collapses newlines differently than intended. - -Fix options: - -1. Use `gh issue edit` with `--body-file` instead of inline `--body`, writing to a temp file that preserves formatting -2. Or use the GitHub API directly (`gh api PATCH`) with proper JSON encoding that preserves newlines - -Want me to fix the skill to use the `--body-file` approach? - -### 13:35 Prompt - -Yes, please fix both skills such that any steps that edit issues use the `--body-file` approach. - -For your convenience, the two skills in question are: - -- `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md` - -- `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` - -### 13:38 Response - -Thought for 2s -Let me look at both skills to find all places where issue bodies are edited. - -Search "issue edit|--body" in **/*shepherd-task-from-assignment-to-ready/SKILL.md 3 lines found -Search "issue edit|--body" in **/*shepherd-task-from-ready-to-merged-to-base/SKILL.md No matches found - -Only the first skill has an issue body edit (line 36).

From our #1840 experience: - -• Phase 1 alone required ~30 minutes of polling + CI evaluation -• Phase 2 went through 6 rounds of review, each involving: fetching comments, reading code, making edits, running tests, committing — that's substantial context accumulation -• The combined skill would stack both phases in one session - -The risk is the LLM loses coherence or starts hallucinating as context fills up, especially during Phase 2's iterative review loop. - -Mitigation options: - -1. Keep the skills separate — invoke Phase 1 and Phase 2 as independent sessions (human triggers Phase 2 after Phase 1 completes). The orchestrator  shepherd-task  becomes documentation rather than a single-session execution. -2. Add a "compact context" instruction at the Phase 1→Phase 2 boundary, telling the LLM to summarize state and discard intermediate polling output. -3. Rely on infinite sessions — the SDK supports compaction events that compress older context automatically. -4. Split Phase 2 internally — each review round could be a separate invocation, with state passed via the PR itself (comments, commits). - -Which direction interests you? Or would you prefer to keep the orchestrator as-is and see if context length becomes an actual problem on the next run? - -### 13:48 Prompt - -The whole point of this is to get long running orchestrated actions. My job is to keep the agents busy. - -Is there a slash command to cause the CLI to start a new session? - -If so, could we bake that into the `copilot-sdk/.github/skills/shepherd-task/SKILL.md` and pepper it in between the called skills? - -### 13:49 Response - -I see  /compact  and  /new  commands: - -•  /compact  — Summarizes conversation history to reduce context window usage. You can provide focus instructions (e.g.,  /compact focus on the PR number and current step ). -•  /new  — Starts a new conversation (fresh session, loses all context). - -The problem: Neither works well baked into a skill: - -•  /new  wipes all state — the Phase 2 skill wouldn't know the PR number, branch, etc. -•  /compact  reduces context but doesn't reset it — and you can't invoke slash commands from within a skill's execution (they're user-level CLI commands, not something the LLM can emit programmatically). - -What would actually work: Add a  /compact  instruction at the Phase 1→Phase 2 boundary in the orchestrator skill, telling the LLM to explicitly request compaction: - -After Phase 1 completes, run `/compact` with focus: "Retain TASK_ISSUE, PR number, branch name, BASE_BRANCH, REPO, and current step." - -The LLM can invoke  /compact  as a tool during execution in  --yolo  mode.

Automate the lifecycle of a child **Task** issue from "assigned to Copilot" through CI passing and review-agent feedback resolution, stopping just before marking the PR as **Ready for review**. -11. -12. ## Inputs -13. -14. - `TASK_ISSUE`: The issue number (e.g., `1850`) or URL of the child task to shepherd. -15. - `BASE_BRANCH`: The base branch the task PR should target (default: `upstream/edburns/1810-java-tool-ergonomics-tool-as-lambda`). -16. - `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). -17. -18. ## Prerequisites -19. -20. - `gh` CLI authenticated with sufficient permissions (issues, PRs, actions, reviews). -21. - The task issue already exists and has a clear description of work to do. -22. - The base branch exists in the repository. -23. -24. --- -25. -26. ## Procedure -27. -28. ### Step 1: Assign the task to @Copilot -29. -30. First, prepend an instruction to the issue body telling Copilot which base branch to use. This must happen **before** assignment to avoid a race condition where Copilot targets `main` instead. -31. -32. **Idempotency:** If the issue body already starts with `**Base branch:**`, skip the prepend (it was already done in a prior run). -33. -34. ```bash -35. # Check if already prepended (idempotency guard) -36. CURRENT_BODY=$(gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body') -37. if echo "$CURRENT_BODY" | head -1 | grep -q '^\*\*Base branch:\*\*'; then -38. echo "Base branch instruction already present — skipping prepend." -39. else -40. # Prepend base branch instruction (use --body-file to preserve markdown formatting) -41. gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body' > /tmp/issue-body-$TASK_ISSUE.md -42. cat > /tmp/issue-body-$TASK_ISSUE-new.md <
    > /tmp/issue-body-$TASK_ISSUE-new.md -51. gh issue edit $TASK_ISSUE -R $REPO --body-file /tmp/issue-body-$TASK_ISSUE-new.md -52. rm -f /tmp/issue-body-$TASK_ISSUE.md /tmp/issue-body-$TASK_ISSUE-new.md -53. fi -54. ``` -55. -56. > **PowerShell equivalent** (when running on Windows): -57. > ```powershell -58. > $body = gh issue view $TASK_ISSUE -R $REPO --json body --jq '.body' | Out-String -59. > if ($body.TrimStart().StartsWith("**Base branch:**")) { -60. > Write-Host "Base branch instruction already present - skipping prepend." -61. > } else { -62. > $instruction = @" -63. > **Base branch:** Create your PR targeting ``$BASE_BRANCH`` (not ``main``). -64. > -65. > **Requirement:** When you open the PR, the very first thing you put in the description must be ``Fixes #$TASK_ISSUE`` where the issue number is this issue for which the PR aims to implement the work. -66. > -67. > -------- -68. > -69. > "@ -70. > $newBody = $instruction + $body -71. > $tmpFile = [System.IO.Path]::GetTempFileName() -72. > Set-Content -Path $tmpFile -Value $newBody -NoNewline -73. > gh issue edit $TASK_ISSUE -R $REPO --body-file $tmpFile -74. > Remove-Item $tmpFile -75. > } -76. > ``` -77. -78. Then assign: -79. -80. ```bash -81. gh issue edit $TASK_ISSUE --add-assignee "@copilot" -R $REPO -82. ``` -83. -84. This triggers Copilot to: -85. 1. Create a topic branch from `$BASE_BRANCH`. -86. 2. Open a draft PR targeting `$BASE_BRANCH`. -87. 3. Push initial commits. -88. -89. **Fallback:** After the PR is created (Step 2), verify it targets `$BASE_BRANCH`. If Copilot ignored the instruction, fix the base: -90. -91. ```bash -92. gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" -93. ``` -94. -95. ### Step 2: Find the corresponding PR -96. -97. Look for the corresponding PR created and mentioned in the issue. The issue will often have text like "linked a pull request that will close this issue". First, try to find the PR this way. If you find it, let `PR_NUMBER` be that PR number. -98. -99. If that doesn't work, wait for Copilot to create the PR. -100. -101. Poll until a PR exists with the task issue linked or with a head branch referencing the issue number. -102. -103. ```bash -104. # Poll every 30 seconds for up to 10 minutes -105. TIMEOUT=600 -106. INTERVAL=30 -107. ELAPSED=0 -108. -109. while [ $ELAPSED -lt $TIMEOUT ]; do -110. PR_NUMBER=$(gh pr list -R $REPO --state open --json number,title,headRefName \ -111. --jq ".[] | select(.title | test(\"$TASK_ISSUE\"; \"i\")) | .number" | head -1) -112. -113. if [ -n "$PR_NUMBER" ]; then -114. break -115. fi -116. -117. sleep $INTERVAL -118. ELAPSED=$((ELAPSED + INTERVAL)) -119. done -120. ``` -121. -122. If no PR is found after timeout, report failure and stop. -123. -124. Once the PR is found, verify and fix the base branch if needed: -125. -126. ```bash -127. # Check the PR targets the correct base branch -128. ACTUAL_BASE=$(gh pr view $PR_NUMBER -R $REPO --json baseRefName --jq '.baseRefName') -129. if [ "$ACTUAL_BASE" != "$BASE_BRANCH" ]; then -130. gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" -131. fi -132. ``` -133. -134. ### Step 3: Wait for initial commits and workflow trigger -135. -136. After the PR is created, Copilot pushes commits which trigger workflow runs. These runs require approval because every Copilot push triggers the "Approve workflows to run" gate. -137. -138. You may be coming to this PR after all the runs have been manually approved. In that case, you need to wait for the runs to complete, then, skip to step 6. Here is how you wait for the runs to complete. -139. -140. ```bash -141. gh pr checks $PR_NUMBER -R $REPO --watch -142. ``` -143. -144. Otherwise, wait for runs to appear in `action_required` status: -145. -146. ```bash -147. # Wait for workflow runs needing approval -148. gh run list -R $REPO --branch "$JTBDTASK_BRANCH" --status action_required \ -149. --json databaseId,name,status --jq '.[].databaseId' -150. ``` -151. -152. ### Step 4: Approve pending workflow runs -153. -154. For each run in `action_required` status on the PR's branch, re-run it. The correct mechanism is `gh run rerun` (the `POST .../actions/runs/{id}/approve` endpoint is for fork PRs only and will return HTTP 403 here). -155. -156. ```bash -157. # Get all action_required runs for the PR branch -158. PENDING_RUNS=$(gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ -159. --json databaseId,conclusion --jq '.[] | select(.conclusion == "action_required") | .databaseId') -160. -161. for RUN_ID in $PENDING_RUNS; do -162. gh run rerun $RUN_ID -R $REPO -163. done -164. ``` -165. -166. ### Step 5: Wait for workflow runs to complete -167. -168. ```bash -169. # Watch all runs on the branch until they complete -170. # Use gh pr checks with --watch for convenience -171. gh pr checks $PR_NUMBER -R $REPO --watch --fail-fast -172. ``` -173. -174. Alternatively, poll with: -175. -176. ```bash -177. gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ -178. --json databaseId,status,conclusion,name \ -179. --jq '.[] | select(.status != "completed")' -180. ``` -181. -182. ### Step 6: Evaluate workflow results -183. -184. **Note:** Ignore failures from the "Block remove-before-merge paths" / "No remove-before-merge directories" workflow. This failure is expected on feature branches and is not a real problem. -185. -186. ```bash -187. # Get check results, excluding the expected "Block remove-before-merge paths" failure -188. RESULTS=$(gh pr checks $PR_NUMBER -R $REPO --json name,state,bucket \ -189. --jq '.[] | select(.bucket == "fail") | select(.name != "No remove-before-merge directories")') -190. ``` -191. -192. If there are real failures (after excluding the expected one), proceed to Step 7. If all pass, proceed to Step 8. -193. -194. ### Step 7: Request changes from Copilot (iteration loop) -195. -196. **Max iterations: 20** -197. -198. When CI fails or review agents flag problems: -199. -200. #### 7.1: Gather failure details -201. -202. ```bash -203. # Get failed run IDs -204. FAILED_RUNS=$(gh run list -R $REPO --branch "$JTBDTASK_BRANCH" \ -205. --status completed --json databaseId,conclusion,name \ -206. --jq '.[] | select(.conclusion == "failure") | .databaseId') -207. -208. # Get logs for failed runs (only failed steps) -209. for RUN_ID in $FAILED_RUNS; do -210. gh run view $RUN_ID -R $REPO --log-failed -211. done -212. ``` -213. -214. #### 7.2: Gather review agent comments -215. -216. ```bash -217. # Get review comments on the PR -218. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ -219. --jq '.[] | select(.user.type == "Bot") | {user: .user.login, body: .body}' -220. -221. # Also get issue-level comments (review agents sometimes post there) -222. gh pr view $PR_NUMBER -R $REPO --comments --json comments \ -223. --jq '.comments[] | select(.author.login | test("bot|copilot|agent"; "i")) | {author: .author.login, body: .body}' -224. ``` -225. -226. #### 7.3: Compose and submit a "Request changes" review -227. -228. Analyze the failures and compose a hybrid message: relevant log excerpts plus a short targeted instruction for Copilot. -229. -230. ```bash -231. # Submit review requesting changes, @mentioning Copilot -232. gh pr review $PR_NUMBER -R $REPO --request-changes --body "$REVIEW_BODY" -233. ``` -234. -235. The `$REVIEW_BODY` should follow this format: -236. -237. ``` -238. @copilot Please fix the following issues: -239. -240. ## CI Failure: [workflow name] -241. -242. -243. -244. **Fix:** [Short, specific instruction on what to change] -245. -246. ## Review Comment from [bot name] -247. -248. > [quoted comment] -249. -250. **Fix:** [Short, specific instruction on what to change] -251. ``` -252. -253. #### 7.4: Wait for Copilot to push fixes -254. -255. After submitting the review, wait for new commits on the branch: -256. -257. ```bash -258. # Get current HEAD SHA -259. CURRENT_SHA=$(gh pr view $PR_NUMBER -R $REPO --json headRefOid --jq '.headRefOid') -260. -261. # Poll for new commits (up to 10 minutes) -262. TIMEOUT=600 -263. INTERVAL=30 -264. ELAPSED=0 -265. -266. while [ $ELAPSED -lt $TIMEOUT ]; do -267. NEW_SHA=$(gh pr view $PR_NUMBER -R $REPO --json headRefOid --jq '.headRefOid') -268. if [ "$NEW_SHA" != "$CURRENT_SHA" ]; then -269. break -270. fi -271. sleep $INTERVAL -272. ELAPSED=$((ELAPSED + INTERVAL)) -273. done -274. ``` -275. -276. #### 7.5: Loop back -277. -278. Return to **Step 4** (approve workflows) and repeat. Track iteration count. If 20 iterations are exhausted without all checks passing, stop and report: -279. -280. ``` -281. SHEPHERD FAILED: Exhausted 20 iterations on PR #$PR_NUMBER for task #$TASK_ISSUE. -282. Manual intervention required. -283. ``` -284. -285. ### Step 8: Address pre-Ready-for-Review comments -286. -287. Even when CI passes, review agents (e.g., "Copilot code review", "SDK Consistency Review Agent") may leave comments that should be addressed before marking ready. -288. -289. #### 8.1: Check for unresolved review comments -290. -291. ```bash -292. # Get all review comments that haven't been resolved -293. gh api "/repos/$REPO/pulls/$PR_NUMBER/reviews" \ -294. --jq '.[] | select(.state == "CHANGES_REQUESTED") | {user: .user.login, body: .body}' -295. -296. # Get pending review threads -297. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ -298. --jq '.[] | select(.user.type == "Bot") | {id: .id, user: .user.login, body: .body, path: .path, line: .line}' -299. ``` -300. -301. #### 8.2: If unresolved comments exist, iterate -302. -303. Use the same pattern as Step 7: compose a review requesting changes with specific instructions, wait for Copilot to push, approve workflows, and check results. This shares the same 20-iteration budget. -304. -305. ### Step 9: Final status report -306. -307. When all checks pass and no unresolved review comments remain: -308. -309. ``` -310. SHEPHERD COMPLETE: PR #$PR_NUMBER for task #$TASK_ISSUE is ready to review for marking as **Ready to review**. -311. All CI checks pass. No unresolved review comments. -312. Next step: Mark as Ready for Review (use separate skill). -313. ``` -314. -315. --- -316. -317. ## Error handling -318. -319. - **PR not created within 10 minutes**: Report and stop. -320. - **Copilot doesn't push after review request within 10 minutes**: Report and stop. -321. - **20 iterations exhausted**: Report and stop. -322. - **API errors**: Retry up to 3 times with 10-second backoff, then report and stop. -323. -324. ## Notes -325. -326. - This skill runs in a `copilot --yolo` session on a Dev Box, executing as the authenticated user. -327. - The skill does NOT mark the PR as "Ready for review" — that is a separate skill. -328. - The `gh api .../actions/runs/{id}/approve` endpoint is the programmatic equivalent of the "Approve and run" button in the GitHub UI. -329. - Review comments from bots/agents are treated the same as CI failures for iteration purposes. -330. - **Do NOT edit any plan/checklist files** (e.g., `1810-ignorance-reduction-for-implementation-plan.md`) to mark tasks as complete. Marking checklist items is outside the scope of this skill. -331. -```` - -

    -300 lines - -```` -1. --- -2. name: shepherd-task-from-ready-to-merged-to-base -3. description: "Use this skill to shepherd a task PR from 'Ready for review' through Copilot code review, local comment resolution, and merge to the specified base branch." -4. --- -5. -6. # Skill: Shepherd Task from Ready for Review to Merged -7. -8. ## Purpose -9. -10. Automate the lifecycle of a task PR from marking as **Ready for review** through Copilot code review comment resolution and merge to the specified base branch. This is a follow-up skill intended to be run after `shepherd-task-from-assignment-to-ready`. -11. -12. ## Inputs -13. -14. - `TASK_ISSUE`: The issue number (e.g., `1850`) or URL of the child task. -15. - `BASE_BRANCH`: The base branch the task PR should target (e.g., `edburns/1810-java-tool-ergonomics-tool-as-lambda`). -16. - `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). -17. -18. ## Prerequisites -19. -20. - The `shepherd-task-from-assignment-to-ready` skill has completed successfully for this task. -21. - `PR_NUMBER` is known (the PR created by Copilot for this task). For discussion: `jtbdtask-pr`. -22. - `gh` CLI authenticated with sufficient permissions. -23. - The PR is currently in draft state with all CI checks passing. -24. -25. --- -26. -27. ## Procedure -28. -29. ### Step 0: Find the PR -30. -31. Look for the corresponding PR created and mentioned in the issue. The issue will often have text like "linked a pull request that will close this issue". First, try to find the PR this way. If you find it, let `PR_NUMBER` be that PR number. -32. -33. If you don't find it, fail the skill and report the error. -34. -35. ### Step 1: Mark the PR as Ready for Review -36. -37. ```bash -38. gh pr ready $PR_NUMBER -R $REPO -39. ``` -40. -41. ### Step 2: Wait for Copilot code review agent to complete -42. -43. The act of marking as Ready for Review triggers the Copilot code review agent. Wait for it to post its findings. -44. -45. Poll the PR comments looking for a batch header matching this pattern: -46. -47. ``` -48. ## Copilot's findings -49. -50. - **Files reviewed:** X/Y changed files -51. - **Comments generated:** N -52. ``` -53. -54. ```bash -55. # Poll every 30 seconds for up to 10 minutes -56. TIMEOUT=600 -57. INTERVAL=30 -58. ELAPSED=0 -59. -60. while [ $ELAPSED -lt $TIMEOUT ]; do -61. FINDINGS=$(gh api "/repos/$REPO/pulls/$PR_NUMBER/reviews" \ -62. --jq '.[] | select(.body | test("Copilot.s findings")) | {id: .id, body: .body}' | tail -1) -63. -64. if [ -n "$FINDINGS" ]; then -65. break -66. fi -67. -68. sleep $INTERVAL -69. ELAPSED=$((ELAPSED + INTERVAL)) -70. done -71. ``` -72. -73. Search for similar text to identify the batch of review findings (`jtbdtask-pr-comments`). -74. -75. If **Comments generated: 0** (or no comments for this round), skip to **Step 18**. -76. -77. When `jtbdtask-pr-comments` has been identified, proceed. -78. -79. ### Step 3: Determine N (number of comments) -80. -81. Extract the number of comments from the **Comments generated:** line in the findings header. There will be exactly N individual review comments in this batch to address. -82. -83. ### Step 4: Fetch upstream and set up local worktree -84. -85. ❌❌❌ This part of the work does not use the remote agent. All comment resolution is done locally. ❌❌❌ -86. -87. ```bash -88. # Fetch upstream to get the topic branch -89. git fetch upstream -90. -91. # Get the currently logged in username -92. GH_CURRENT_USER=$(gh api /user --jq '.login') -93. -94. # Get the topic branch name for the PR -95. JTBDTASK_BRANCH=$(gh pr view $PR_NUMBER -R $REPO --json headRefName --jq '.headRefName') -96. -97. # Create a worktree for local review work -98. git worktree add "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" "upstream/$JTBDTASK_BRANCH" -99. ``` -100. -101. For discussion, this worktree is the `jtbdtask-pr-comments-comment-worktree`. -102. -103. ### Step 5: Gather all review comments -104. -105. ```bash -106. # Get all review comments from the Copilot code review batch -107. gh api "/repos/$REPO/pulls/$PR_NUMBER/comments" \ -108. --jq '.[] | select(.user.login == "copilot-pull-request-reviewer") | {id: .id, path: .path, line: .line, body: .body, in_reply_to_id: .in_reply_to_id}' -109. ``` -110. -111. Identify each individual comment. Each has a unique `id` (e.g., `discussion_r3456155645`-style reference). For discussion, each is a `jtbdtask-pr-comments-comment`. -112. -113. ### Step 6: Address each review comment locally -114. -115. For each review comment (`jtbdtask-pr-comments-comment`), working in the `jtbdtask-pr-comments-comment-worktree`: -116. -117. #### 6.1: Evaluate the comment -118. -119. - Carefully consider the comment and judge its merit. -120. - **If there is no merit:** mark the comment as resolved with an explanatory note (defer the resolution reply until Step 13). -121. - **If there is merit:** evaluate the suggested remedy. -122. - If you agree with the suggested remedy, proceed with it. -123. - If you disagree with the suggested remedy, devise a better remedy and proceed with that. -124. -125. #### 6.2: Implement the fix -126. -127. - Implement the remedy in the `jtbdtask-pr-comments-comment-worktree`. -128. - Use the appropriate language coding skill in `.github/skills/` to know how to run tests. -129. - ❌❌❌ DO NOT RUN THE FULL TEST SUITE at this stage. ❌❌❌ Only run the tests directly related to the fix, in isolation. -130. - **If the commit has to do with Java, YOU MUST ALWAYS RUN `mvn spotless:apply` in the java directory before each commit.** -131. -132. #### 6.3: Commit locally (do not push) -133. -134. - Once the relevant tests pass, commit the fix. -135. - ❌❌❌ Do NOT push yet. ❌❌❌ -136. - Keep track of the commit hash — you will need it when replying to the review comment. -137. -138. ### Step 7: Push all fixes to upstream -139. -140. Once **all** N review comments have been addressed locally: -141. -142. ```bash -143. # Push from the worktree to upstream -144. cd "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" -145. git push upstream HEAD:$JTBDTASK_BRANCH -146. ``` -147. -148. ### Step 8: Reply to each review comment and resolve the thread -149. -150. For each `jtbdtask-pr-comments-comment`: -151. -152. 1. State what you did to address the comment. If the action corresponds to a commit, include the hash: "Fixed in ``". -153. 2. Reply to the comment. -154. 3. Resolve the review thread. -155. -156. To reply to the comment: -157. -158. ```bash -159. # Reply to a specific review comment -160. gh api --method POST "/repos/$REPO/pulls/$PR_NUMBER/comments/$COMMENT_ID/replies" \ -161. -f "body=Fixed in $COMMIT_HASH. [explanation of the fix]" -162. ``` -163. -164. To resolve the thread, use the GraphQL API (the REST API does not support thread resolution): -165. -166. ```bash -167. # 1. Get the GraphQL thread node ID for the comment -168. THREAD_ID=$(gh api graphql -F number=$PR_NUMBER -f query=' -169. query($number: Int!) { -170. repository(owner: "github", name: "copilot-sdk") { -171. pullRequest(number: $number) { -172. reviewThreads(first: 100) { -173. nodes { -174. id -175. isResolved -176. comments(first: 1) { nodes { databaseId } } -177. } -178. } -179. } -180. } -181. }' --jq ".data.repository.pullRequest.reviewThreads.nodes[] | select(.comments.nodes[0].databaseId == $COMMENT_ID) | .id") -182. -183. # 2. Resolve the thread -184. gh api graphql -f query=" -185. mutation { -186. resolveReviewThread(input: {threadId: \"$THREAD_ID\"}) { -187. thread { id isResolved } -188. } -189. }" -190. ``` -191. -192. ### Step 9: Wait for CI to run -193. -194. The push triggers CI/CD. Use the same approach as `shepherd-task-from-assignment-to-ready` Steps 5, 6, and 7 to: -195. -196. 1. Wait for workflow runs to complete (`gh pr checks $PR_NUMBER -R $REPO --watch`). -197. 2. Evaluate results (excluding the expected "Block remove-before-merge paths" / "No remove-before-merge directories" failure). -198. 3. If there are real CI failures, gather logs and fix locally, commit, and push again. Repeat until CI passes. -199. -200. **Note:** Ignore failures from the "Block remove-before-merge paths" / "No remove-before-merge directories" workflow. This failure is expected on feature branches and is not a real problem. -201. -202. ### Step 10: Re-request Copilot review -203. -204. ```bash -205. gh pr edit $PR_NUMBER -R $REPO --add-reviewer "copilot-pull-request-reviewer" -206. ``` -207. -208. ### Step 11: Loop back -209. -210. Go back to **Step 2**. Wait for the Copilot code review agent to post new findings. -211. -212. **Max iterations: 8.** If exhausted, report failure and stop: -213. -214. ``` -215. SHEPHERD FAILED: Exhausted 20 iterations on PR #$PR_NUMBER for task #$TASK_ISSUE. -216. Manual intervention required. -217. ``` -218. -219. ### Step 18: Final checks before merge -220. -221. Verify: -222. - The only failed check is "Block remove-before-merge paths" / "No remove-before-merge directories". -223. - All other checks pass. -224. -225. ### Step 19: Clean up worktree -226. -227. ```bash -228. # Remove the worktree -229. git worktree remove "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" -230. -231. # Remove the local branch tracking the PR topic branch (if created) -232. git branch -D "$JTBDTASK_BRANCH" 2>/dev/null || true -233. ``` -234. -235. ### Step 20: Verify base branch -236. -237. ❌❌❌ Ensure the base branch is NEVER `main` ❌❌❌ and always the `BASE_BRANCH` from this invocation. -238. -239. ```bash -240. ACTUAL_BASE=$(gh pr view $PR_NUMBER -R $REPO --json baseRefName --jq '.baseRefName') -241. if [ "$ACTUAL_BASE" = "main" ]; then -242. echo "ERROR: PR base is 'main' — must be '$BASE_BRANCH'. Fixing..." -243. gh pr edit $PR_NUMBER -R $REPO --base "$BASE_BRANCH" -244. fi -245. ``` -246. -247. ### Step 21: Handle merge conflicts -248. -249. If there are conflicts between the PR branch and `BASE_BRANCH`: -250. -251. ```bash -252. # Check for merge conflicts -253. MERGEABLE=$(gh pr view $PR_NUMBER -R $REPO --json mergeable --jq '.mergeable') -254. if [ "$MERGEABLE" = "CONFLICTING" ]; then -255. # Resolve conflicts locally in the worktree -256. cd "$GH_CURRENT_USER/review-copilot-pr-$PR_NUMBER" -257. git fetch upstream -258. git rebase "upstream/$BASE_BRANCH" -259. # Resolve conflicts, then: -260. git rebase --continue -261. git push upstream HEAD:$JTBDTASK_BRANCH --force-with-lease -262. fi -263. ``` -264. -265. ### Step 22: Merge the PR -266. -267. ```bash -268. gh pr merge $PR_NUMBER -R $REPO --merge --delete-branch -269. ``` -270. -271. This merges the work to `BASE_BRANCH`. -272. -273. ### Step 23: Close the corresponding issue -274. -275. ```bash -276. gh issue close $TASK_ISSUE -R $REPO -277. ``` -278. -279. ### Step 24: Final status report -280. -281. ``` -282. SHEPHERD COMPLETE: PR #$PR_NUMBER for task #$TASK_ISSUE has been merged to $BASE_BRANCH. -283. ``` -284. -285. --- -286. -287. ## Error handling -288. -289. - **Copilot review agent doesn't post within 10 minutes**: Report and stop. -290. - **20 iterations exhausted**: Report and stop. -291. - **Merge conflicts that cannot be auto-resolved**: Report and stop. -292. - **API errors**: Retry up to 3 times with 10-second backoff, then report and stop. -293. -294. ## Notes -295. -296. - This skill runs in a `copilot --yolo` session on a Dev Box, executing as the authenticated user. -297. - All review comment resolution is done **locally** — not via the remote Copilot coding agent. -298. - The step numbering intentionally skips from 11 to 18 to align with the original procedure description. -299. - **Do NOT edit any plan/checklist files** (e.g., `1810-ignorance-reduction-for-implementation-plan.md`) to mark tasks as complete. Marking checklist items is outside the scope of this skill. -300. -```` - -

Should defensively handle null. - - **Merit: Yes.** Adding a null check for the varargs array itself is defensive programming. Simple fix. - -2. **Comment 3508555480** (ParamSchema.java:27): Class Javadoc says "runtime counterpart to SchemaGenerator" but doesn't inspect generics/object members like SchemaGenerator does. - - **Merit: Yes.** The Javadoc is slightly over-promising and should clarify what ParamSchema actually covers. - -3. **Comment 3508555496** (ParamSchema.java:103): `forType` Javadoc claims to mirror SchemaGenerator output but doesn't handle Optional, List items, or Map additionalProperties. - - **Merit: Yes.** Same issue—the wording needs to be more precise about what's actually supported. - -4. **Comment 3508555520** (ParamCoercion.java:124): Javadoc mentions falling back to ObjectMapper.readValue for complex defaults, - - **Merit: Partial.** The fallback exists in the code, but Param's constructor would reject those types anyway. The documentation should frame this as a safety mechanism rather than a documented feature. - -5. **Comment 3508555532** (ParamSchema.java:61): PR claims these are consumed by ToolDefinition.from* overloads but they're not used in this PR. - - **Merit: No strong merit.** This is intentional—Phase 4.3 extracts the internals while Phase 4.2 handles the wiring later. The staging is deliberate even if the PR description could be clearer. - -Now I'm going to fix the documentation issues in comments 1-4.* - ---- - -86m 35s - -### Copilot - -Now let me evaluate and address each comment.

During `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md`, after the issue was assigned work stopped waiting for the PR to be created. I had to intervene with this prompt: - - > The PR has been created. - -2. After completing `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md` but before starting `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` I had to intervene with this text - - > It seems you got stuck. Please proceed with Phase 2. - -Let's look at that first one.

Let me update the skill: - -Edit SKILL.md +48 -9 - -Now let me also update the  shepherd-task-from-ready-to-merged-to-base  Step 0 with the same approach since it also needs to find the PR: - -Read SKILL.md L29:35 (7 lines read) - -Edit SKILL.md +6 -2 - -Now let me commit these skill improvements: - -Shell Stage skill changes 4 lines… -cd C:\Users\edburns\workareas\copilot-sdk git add .github/skills/shepherd-task-from-assignment-to-ready/SKILL.md .… -Shell Commit skill improvements 13 lines… -cd C:\Users\edburns\workareas\copilot-sdk git commit -m "fix(skills): improve PR discovery with multi-strategy pol… - -Done. Here's what I changed to prevent the first issue from recurring: - -Root cause: The polling only searched PR titles and branch names for the issue number ( 1876 ). Copilot named the PR "feat(java): implement ParamSchema + ParamCoercion..." with branch  copilot/edburns1810-java-tool-ergonomics-tool-as-lambda-im  — neither contained  1876 . - -Fix (3 strategies, tried each iteration): - -1. Issue timeline API — queries GitHub's timeline for cross-referenced PRs (most reliable since "Fixes #1876" creates a link) -2. PR body search — searches open PR bodies for  #1876  -3. Title/branch regex — original fallback - -Also bumped the timeout from 10→15 minutes since Copilot can take that long. - -Would you like to discuss the second stuck point (Phase 1→Phase 2 transition) as well? - -### 16:12 Prompt - -Not just yet. Regarding the "find the linked PR" aspect, does the skill have a backup step that searches for the text "Copilot linked a pull request that will close this issue"? Because that text seems to always appear when Copilot creates the linked PR. - -### 16:14 Response - -Good question. My Strategy A (issue timeline API) is the programmatic equivalent of that — when Copilot links a PR via "Fixes #1876", it creates a  cross-referenced  event in the timeline. However, there's a more direct approach too. - -Let me check if there's a simpler way to get linked PRs: - -Shell Check timeline events for issue 1876 2 lines… -# Let's see what the timeline actually looks like for issue 1876 gh api "/repos/github/copilot-sdk/issues/1876/tim… - -Yes — the  cross-referenced  event is exactly what "Copilot linked a pull request that will close this issue" corresponds to in the API. My Strategy A already queries this. But let me also check if there's a comment-based signal: - -Shell Check issue comments for linked PR text 1 line… -# Check if there's also a comment with that text gh api "/repos/github/copilot-sdk/issues/1876/comments" --jq '.[]… - -No comments — it's only in the timeline events, not the comments API. So Strategy A already covers this via the  cross-referenced  event with actor  Copilot . That's the API representation of the "Copilot linked a pull request that will close this issue" text you see in the UI. - -The skill is already correct. The problem in our run was that Strategy A didn't exist yet — we were only using the title/branch regex (old Strategy C). With the updated skill, the timeline query would have found PR #1877 immediately once Copilot linked it. - -Want me to add an explicit note in the skill mentioning this UI text ↔ API mapping for clarity? - -### 16:14 Prompt - -No. Now on to the second pause. - -I wonder if it would be better to implement `copilot-sdk/.github/skills/shepherd-task/SKILL.md` as a shell script that manually invokes `copilot --yolo` with the Phase 1 and Phase 2 prompts individually? - -In this way we can avoid having the "/compact" step because there would be separate copilot instances. - -If we did that, what is the most deterministic way for the invoking shell script to know the "exit code" like status of `copilot-sdk/.github/skills/shepherd-task-from-assignment-to-ready/SKILL.md`? - -### 16:19 Response - -Asked user I see two main approaches for detecting Phase 1's exit status from the shell script: 1. **Check PR sta… -└ User selected: Option 1: Shell script verifies PR state with gh CLI after copilot exits (Recommended) - -Good choice. Here's the design: - -The shell script would: - -1. Launch  copilot --yolo  with Phase 1 prompt → let it run to completion -2. After exit, verify Phase 1 success by checking: -• An open PR exists linked to the issue (using the multi-strategy search) -• PR targets the correct base branch -• All CI checks pass (excluding "No remove-before-merge directories") -• No unresolved review comments from bots -3. If verified → extract  PR_NUMBER  → launch  copilot --yolo  with Phase 2 prompt -4. After Phase 2 exits, verify the PR was merged to the base branch - -This means the shell script is the source of truth for state transitions — copilot sessions are "fire and forget" workers, and the script does the verification. - -Shall I implement this as a shell script now? - -### 16:20 Prompt - - Yes, write it twice. 1st as a PowerShell script, then as a bash script. Write both of them to the `1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge` directory. Name the script `shepherd-task`. Make it take three parameters, in this order: - -- `TASK_ISSUE`: The issue number (e.g., `1841`) or URL of the child task to shepherd. -- `BASE_BRANCH`: The base branch the task PR should target (e.g., `edburns/1810-java-tool-ergonomics-tool-as-lambda` -- `REPO`: Repository in `OWNER/REPO` format (default: `github/copilot-sdk`). - No defaults. - - ### 16:26 Response - - -List directory 1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge 5 files found - -Create shepherd-task.ps1 +193 -Create shepherd-task.sh +154 - -Shell Commit shepherd scripts 11 lines… -cd C:\Users\edburns\workareas\copilot-sdk git add 1810-java-tool-ergonomics-tool-as-lambda-remove-before-merge/she… - -Done.

It's a ref name on the target repo, not a remote-tracking ref. - -The fix is to strip any remote prefix from  $BaseBranch  before comparison: - -# Normalize: strip remote prefix (e.g., "upstream/foo" → "foo") -$normalizedBase = $BaseBranch -replace '^[^/]+/', '' - -Or validate at invocation time that  $BaseBranch  should be passed without the  upstream/  prefix. - -Regarding your timing hypothesis: While adding retry loops for the  MERGED  state check (line 170-174) could be useful as a robustness improvement (GitHub's API can have eventual consistency delays), it would not have helped here — the merge was already detected. The issue is purely a string comparison mismatch between a local remote-tracking ref name and GitHub's branch name format. - -### 17:48 Response - -Done. The check now strips the remote prefix (e.g.,  upstream/ ) from  $BaseBranch  before comparing against GitHub's  baseRefName , which never includes a remote prefix. - -### 17:48 Prompt - -Do the same thing for the bash variant - -### 17:49 Response - -Done.

Step 1 —  PENDING_RUNS  would be empty, so the  for  loop simply doesn't execute (no-op). -2. Step 2 —  gh pr checks --watch  reports the current state of checks. If they're already complete (or there are none pending), it returns immediately with success. - -The "Error handling" section also explicitly states: "No pending runs found: This is not an error — it means runs were already approved (possibly manually). Proceed directly to waiting for completion." - -So the skill is safe to call idempotently even when there's nothing to approve. - -### 19:18 Prompt - -Now that we have `copilot-sdk/.github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md` as an invocable skill, I want to pepper it in to `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` to address a problem I observed where there were pending workflows that I did not expect to be there. - -Insert a call to `copilot-sdk/.github/skills/shepherd-task-approve-workflows-and-wait-for-completion/SKILL.md` before steps 5, 10 and 18 in `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md`. - -Renumber the steps in `copilot-sdk/.github/skills/shepherd-task-from-ready-to-merged-to-base/SKILL.md` accordingly. - -### 19:23 Response - -Now I'll make the edits.

The issue is almost certainly the  agent_assignment  object in the API call. - -The problem: The commit replaced the working  gh issue edit --add-assignee "@copilot"  approach with a  POST /repos/{owner}/{repo}/issues/{issue_number}/assignees  call that includes an  agent_assignment  field. This field is likely not a supported parameter on that endpoint (or is an undocumented/experimental feature that isn't behaving as expected). - -What's happening: - -1. The API call probably succeeds in assigning  copilot-swe-agent[bot]  (the assignee part works) -2. But the  agent_assignment  payload either confuses the backend or is silently ignored/malformed, causing the Copilot agent to error when it tries to start work - -Evidence: The error message "The agent encountered an error and was unable to start working" indicates the assignment did trigger Copilot, but Copilot couldn't process the request — consistent with a malformed or unsupported initialization parameter. - -Recommended fix: Revert to the previous approach (prepend body +  gh issue edit --add-assignee "@copilot" ), or at minimum use the proven assignment method while investigating whether  agent_assignment  is actually a supported API field. Want me to revert this commit? - -### 20:54 Prompt - -Yes. Revert the commit. - -After you've reverted the commit, we need to find another way to strengthen the system so when Copilot starts working it uses the correct base branch. - -This is absolutely imperative because the description of the issue refers to plan files only present on the correct base branch.

Let me think about what we already know and what we can strengthen: -Current approach: -1. Prepend "Base branch: Create your PR targeting `$BASE_BRANCH`" to the issue body -2. Assign Copilot -3. After PR is created, verify the base and fix with `gh pr edit --base` if wrong -The problem is that Copilot sometimes ignores the body instruction and defaults to `main`. The fallback (fixing the base after PR creation) works but doesn't help with the fact that Copilot's working branch was branched from `main` — changing the PR base doesn't rebase the commits. -I could try making the instruction more prominent by repeating it in the title and body, adding it as a comment after assignment, or using labels to signal the base branch. But the real bottleneck is that even if I fix the PR base afterward, the commits are still based on the wrong branch — I'd need to rebase them onto the correct base to fully resolve it. commits actually contain the plan files and are based on the correct branch. Let me put these improvements into action. - -Now let me think about strengthening. The current approach has the body prepend + a post-creation fallback ( gh pr edit --base ). The weakness is: - -1. Copilot may not read the body carefully before branching -2. Even if we fix the PR base after creation, Copilot's working branch may have been created from  main  — so the plan files referenced in the issue won't exist on its branch - -Let me strengthen the skill with multiple reinforcement layers: - -Read SKILL.md L28:93 (66 lines read) - -Now I'll strengthen the skill. My approach: - -1. Make the body prepend much more prominent — use a heading-level instruction with explicit warnings -2.

The lambda closes over the local, making it explicit that schema building, coercion, and result formatting all use the same mapper instance.
