Conversation
The product was never coding-only. INTEGRATION_TYPES holds twelve harnesses and two of them — Hermes, a Slack/Telegram gateway, and OpenClaw, a self-hosted assistant — were never coding tools. But the strings a stranger reads said otherwise, and the breadth evidence sat under labels that converted it back: README's twelve-logo grid, containing both gateways, was headed "Supported agent CLIs". So "harness" is promoted here, not invented — docs/reference/harnesses.mdx has been titled "Agent harnesses" the whole time. Rewrites the surfaces that render the project's identity: the README hero, package.json's description and keywords, SECURITY.md, the types.ts header, the docs index and quickstart, reference/harnesses, two sessions captions, the local dashboard, and the audit share templates. Each defines the harness ostensively on first use with an example that is not a terminal, and frames coding CLIs as the class covered deepest rather than as the category. reference/harnesses is promoted onto the onboarding path in all fifteen locale navs: it is the only page answering which kinds of agent are covered, and it sat in the sixth and last tab. Three counts had rotted silently. README advertised "30 built-in policies" in three places; the real number is 40. __tests__/scripts/copy-counts.test.ts now derives every count in copy — harnesses, policies, canonical events, and the harnesses on which PreToolUse and Stop blocking is verified — from types.ts, builtin-policies.ts and enforcement-capability.ts, and fails when prose disagrees. It also asserts the README names no harness absent from INTEGRATION_TYPES, which is what makes the twelve-harness claim checkable by the engineer most likely to check it. Separately: the fourteen translation links resolved to docs-old/i18n/, frozen when the Mintlify site replaced it, while translate-docs.yml writes docs/i18n/. Non-English readers got a README that would never be updated again, and the two sets had already diverged. Repointed, and the drift guard asserts the target.

📝 WalkthroughWalkthroughThe release updates reposition Failproof around observability and enforcement across agent harnesses. Documentation, navigation, package metadata, interface copy, security scope, audit output, and source-backed validation now reflect 12 harnesses and 40 built-in policies. ChangesAgent harness positioning
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR may lead readers to expect the Python SDK to block policy violations when it currently provides observability, audit, and session history without enforcing policies on its own; the copy guard also does not cover every enforcement claim.

- Medium/High Do not promise built-in policy enforcement for Python SDK agents — The new docs say agents with no harness report through the Python SDK and that “the same policies” apply to all of them (docs/index.mdx:9); the harness reference and README make the same claim. However, docs/reference/python-sdk.mdx states that the SDK provides tracing and auditing only, and that preventing an unsafe action requires a separate runtime enforcement hook. An operator who only instruments a custom agent with this SDK can therefore believe a policy blocks a tool call when it merely records the run. (

Four fixes from the CodeRabbit review, three of them real.
The three-class split disagreed with itself. README called the third class
"agent runtimes", while types.ts, reference/harnesses.mdx and the landing
llms.txt all name it "your own agents through the Python SDK" and put Factory,
Devin, Antigravity and Goose in the coding-CLI class. README was the odd one out
and is now aligned — this matters more than a wording nit, because the whole
repositioning rests on the class split being the same everywhere a reader checks.
The audit report understated its own coverage and overstated its own findings.
The footer named six integrations ("Claude Code, Codex, Copilot, Cursor, OpenCode,
and Pi") when runAuditInner defaults to all twelve, in an artifact users paste
publicly. And the TL;DR said the agent did N things "failproofai would have
stopped" — but totalHits folds in detectorRows (source "audit-detector"), which
are replay-only findings with no builtin behind them; their own fix column renders
"audit-only", and the slipping-through section already calls them "caught by
audit, not blocked". "Caught" is true of both halves; "would have stopped" was not.
The types.ts comment claimed the drift guard asserts "every count in user-facing
copy". It pins five derived numbers and scans three files for the policy and
harness counts. Comment now says that.

But docs/reference/python-sdk.mdx:7-12 says the SDK supplies tracing/auditing and that preventing an unsafe action requires a separate runtime enforcement hook. A custom agent using only the documented SDK path therefore receives telemetry, not the built-in enforcement this new copy implies. (
docs/index.mdx:9)
CodeRabbit caught a real overclaim, and chasing it down surfaced a worse one underneath. The stated claim was "twelve harnesses across three classes — coding CLIs, chat and assistant gateways, and your own agents through the Python SDK. Same events, same policies, same session history." Two things wrong with that. The arithmetic: the twelve ARE ten coding CLIs plus two gateways, so an SDK-instrumented agent is not among them and is not a third class of them — it is a separate door. And the capability: reference/python-sdk.mdx has always said plainly that "preventing an unsafe action before it executes also requires an enforcement hook in your runtime". The SDK reports events; it does not sit in the tool-call path. So it delivers tracing, sessions, evaluations and audits WITHOUT enforcement, and "same policies" was false for that door. This is the exact failure mode this whole PR exists to prevent. The repositioning asks readers to accept a broader claim about scope, and it only survives if every number and every capability holds when someone checks. A reader who follows "same policies" to the SDK page finds it contradicted in the first paragraph. Corrected in README, docs/index, quickstart, reference/harnesses and the types.ts header, each now stating the two-class split and naming the SDK's limit rather than implying it away. reference/harnesses gets the fullest version, since that is where someone goes to check. The drift guard grows from 10 tests to 14 and now asserts what the comment promised rather than a subset: every translation link resolves to a file on disk (the previous check only ruled out the frozen tree, so a typo'd locale still passed), every shipped harness appears on the harnesses page by display name with the map keyed exhaustively off INTEGRATION_TYPES, the enforcement split in the quickstart matches the capability matrix, and no copy describes the Python SDK as carrying policies. Also fixes a pre-existing typo in the translation nav: Руссий -> Русский. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PvCWBVgUpnJcMpuztkm2tW

- Medium/High Qualify the claim that every policy applies to every harness — README.md:32-34 and docs/index.mdx:9 state that the “same events” and “same policies” apply to every one of the 12 harnesses; docs/reference/harnesses.mdx:12 makes the same policy claim. This is contradicted by that page’s own line 23 (“A policy can only act on events the harness exposes”) and the capability matrix: for example, src/hooks/types.ts:153-168 maps Hermes to only five event types, while the canonical set has 29 events (src/hooks/types.ts:1002-1046). Policies that subscribe to unsupported lifecycle, stop, or permission events therefore cannot apply on Hermes and other limited harnesses. (

- Medium/High Qualify the claim that every policy applies to every harness — README.md:33 says the "same policies" apply whichever harness an agent runs in; docs/index.mdx:9 and docs/reference/harnesses.mdx:12 repeat it. However, Hermes maps only five native events and emits no Stop event (src/hooks/types.ts:153-168), while the five require-*-before-stop built-ins subscribe to Stop (src/hooks/builtin-policies.ts:2535-2606). The capability model explicitly says those policies are inapplicable on Hermes (src/hooks/types.ts:148-149). (

Why
Everyone reading failproofai concludes we are a coding-agent tool. We are not — we
are observability and enforcement for agent harnesses, and coding CLIs are one
of three classes we hook.
A deep audit across this repo, the landing site and AgentEye found 199 findings
over 12 surfaces, but the diagnosis is narrower than that number suggests: the
perception is manufactured by about fifteen strings, and the breadth evidence
already exists and is already correct underneath them. README's twelve-logo grid
already contains Hermes (Slack/Telegram gateway) and OpenClaw (self-hosted
assistant) — under a heading that called them CLIs.
docs/reference/harnesses.mdxhas been titled "Agent harnesses" the whole time.
INTEGRATION_TYPESis twelvenames, two of which were never coding tools.
So "harness" is promoted here, not invented — the only version of this move
that survives an engineer reading
src/hooks/types.ts.What changed
Identity strings — the README hero,
package.jsondescription and keywords,SECURITY.md, and thetypes.tsheader. Each names the harness and defines itostensively on first use with at least one example that is not a terminal.
README structure — "Supported agent CLIs" becomes "Supported harnesses" (the
grid below it is unchanged; only the label converted breadth back into coding-CLI
proof). "Session visibility", three lines out of 221, becomes a real
Observability section covering the free local dashboard and Failproof AI
Observability. The documentation table splits into Start / Observe / Enforce /
Instrument your own agent — every row previously pointed at an enforcement page
while the docs site leads with the observability tabs. The "what it stops" table
is reselected to span harness classes, keeping
block-rm-rfandblock-force-pushas the developer favourites they are.
Docs — index, quickstart (now branches for harness vs Python SDK before the
Node.js prerequisite disqualifies a non-coding reader),
reference/harnesses, andtwo
sessions/captions.reference/harnessesis promoted onto the onboardingpath in all fifteen locale navs: it is the only page answering which kinds of
agent are covered, and it sat in the sixth and last tab.
Product copy — the local dashboard's policies page, the CLI wizard and manager
headers, the audit report output, and the 20 share templates (the company's
most-shared user-generated copy, which said "my coding agent" thirteen times).
Counts, and the guard
Three counts had rotted silently: README advertised 30 built-in policies in
three places; the real number is 40. Verified from source before writing any
copy — 12 harnesses, 40 policies, 29 canonical events, PreToolUse blocking on all
twelve harnesses, Stop blocking on eight of them.
__tests__/scripts/copy-counts.test.tsderives all of these fromtypes.ts,builtin-policies.tsandenforcement-capability.tsand fails when prosedisagrees. It also asserts the README names no harness absent from
INTEGRATION_TYPES— which is what makes the twelve-harness claim checkable bythe engineer most likely to check it — and that Hermes and OpenClaw stay named,
since dropping them would silently remove the breadth claim's evidence.
Unrelated bug fixed on the way
The fourteen translation links resolved to the frozen
docs-oldi18n tree, leftbehind when the Mintlify site replaced it (
109e3725), whiletranslate-docs.ymlwrites the
docsi18n tree (last updated54d95ed6). The two sets had alreadydiverged, so every non-English reader got a README the pipeline would never update
again. Repointed, and the drift guard asserts the target.
Follow-ups not in this PR
FailproofAI/agenteye#629— the landing site names Gemini CLI, deep agentsand langgraph (none in
INTEGRATION_TYPES) and omits Factory, Devin andAntigravity (all of which ship). Needs a build-or-remove decision.
those edits are prepared separately.
and the governance policies shown in
hooks.png(pii_redaction,content_safety_check,rate_limiter,budget_guard) are demo data, notshipped. A gateway operator persuaded by this copy reaches the catalog and finds
nothing aimed at them.
Testing

English lands first; the localized doc trees and translated READMEs are
regenerated by
translate-docs.yml, never hand-edited. Before that run, add"harness" to the translator glossary and check de, ja, zh and ko — they rendered
"coding agents" most idiomatically last time, and an unglossed "harness" comes back
as "framework" or "tool", re-manufacturing this exact problem in fourteen
languages.

Summary by CodeRabbit
Review round
CodeRabbit surfaced one inconsistency I had introduced and two pre-existing
inaccuracies, all fixed in
529f20bc:"agent runtimes";
types.ts,reference/harnesses.mdxand the landingllms.txtall call it "your own agents through the Python SDK" and put Factory,Devin, Antigravity and Goose in the coding-CLI class. README was the odd one
out. This matters more than a wording nit — the repositioning rests on the class
split reading the same everywhere someone checks.
publicly said the agent did N things "
failproofaiwould have stopped", buttotalHitsfolds indetectorRows(sourceaudit-detector) — replay-onlyfindings with no builtin behind them, whose fix column renders
audit-onlyandwhich the slipping-through section already labels "caught by audit, not
blocked". Now "caught", which is true of both halves.
runAuditInnerdefaults to all twelve.types.tscomment claimed the guard asserts "every count in user-facingcopy"; it pins five derived numbers and scans three files. Comment now says so.
Руссий→Русский.Re-verified after: 209 files, 3888 tests passing,
tscclean.Second round: the Python SDK was not one of the twelve
CodeRabbit's README finding was right, and chasing it down surfaced a worse error
underneath it. The copy said "twelve harnesses across three classes — coding CLIs,
chat gateways, and your own agents through the Python SDK. Same events, same
policies, same session history."
Both halves were wrong. The arithmetic: the twelve are ten coding CLIs plus
two gateways, so an SDK-instrumented agent is not among them and is not a third
class of them — it is a separate door. The capability:
docs/reference/python-sdk.mdxhas always stated that preventing an unsafe action"also requires an enforcement hook in your runtime". The SDK reports events; it
does not sit in the tool-call path. So it delivers tracing, sessions, evaluations
and audits without enforcement, and "same policies" was false for that door.
This is precisely the failure mode this PR exists to prevent — a reader who
follows "same policies" to the SDK page finds it contradicted in the first
paragraph, and the whole broader claim loses credibility with it. Corrected in
README,
docs/index, quickstart,reference/harnessesand thetypes.tsheader.The same correction is applied to the landing site in
FailproofAI/platform#515(e3661d6), which matters more there: llms.txt andschema.org are read by systems that will never see the correction.
The drift guard grew from 10 tests to 14 and now asserts what its comment
promised rather than a subset:
ruled out the frozen tree, so a typo'd locale still passed;
