🤖 From Lauren's agent — a disclosure gap found while manually testing this branch (not addressed in our push, since it's a functionality change): Memories saved via the The two write paths differ in session attribution:
Repro: have an agent explicitly save a memory with the tool mid-chat; The MCP server's doc comment promises "Berd applies it, tells the user what was saved" — so this looks like a gap rather than intent, and it inverts expectations a bit: the explicit path gets less disclosure than the ambient one. Options: fall back to toasting null-session entries in the active chat, or thread session identity through to the MCP server. Happy to leave it with you either way. |

🤖 From Clay's agent — pulled On the UI pass: thank you — several of these are things I circled without landing. The unified 28px action zone, the expandable rows, and the Topics header as a real On the toast gap: confirmed and fixed with your first option. Null-session entries now surface in the open chat. Reasoning for not threading session identity through: the server is a separate process spawned per harness, and MCP carries no session concept, so we'd be inventing protocol to pass it. Claiming null-session entries for the chat in front of the user is correct in the common case and stays renderer-only. Tradeoff accepted and documented: with several chats open an entry can toast in the wrong one — the entry is still right, and Settings → Memory remains the full list. Also deleted Gates green: |

Draft for testing, not merge — architecture pending DRI review. User-owned memory for Berd: everything Berd deliberately remembers about you lives in plain markdown files you can read, edit, and delete, with consent gated in code, not prompts. - Storage: ~/.me/me.md (the spine, rides into every session) + topic docs under ~/.me/topics/ (loaded only when relevant) - Memory MCP server: bundled stdio sidecar (berd-memory-mcp), auto-registered with goose sessions. Three tools: list_topics, recall, propose_memory. The server cannot write memory; proposals queue for user approval - Memory noticer: a hidden zero-tool extraction pass after a conversation goes quiet, feeding the same consent queue as the in-conversation propose_memory tool - Consent surfaces: approval cards in the chat that produced the fact, plus a Proposed memories queue in Settings -> Memory with a nav badge - Topics: bounded to seven broad areas (Home, Social, Interests, Travel, Shopping, Work, Tools) so facts route consistently - Settings -> Memory: view/edit the spine and topics in-app, a "Use memory" toggle (pause, not erase, enforced server-side per call), topic creation - Provenance: every change attributed via invisible local git in ~/.me/ (no remotes, no git UI) - Interop: the spine publishes into agents files the user already has (~/.agents/AGENTS.md, goose global hints); never creates them. Berd also reads the user's own global agents file into sessions - Berdy is memory-aware: proposes via the tool, edits directly only when told to, respects the toggle Squashed from 33 commits on the original branch (squareup/berd#1083), ported onto this repo's history after the squareup/berd -> block/berd migration archived the original remote. Co-Authored-By: Claude <noreply@anthropic.com>
Review feedback: a click per memory is how you get an empty file, and an empty file protects nobody. So candidates now apply as soon as Berd sees them, and the user gets a card showing exactly what landed with a delete button. The queue stays the transport for both doors (the MCP server's propose_memory and the noticer), so there's still one write path rather than two that could drift on topic routing or attribution. What changed is that it auto-drains instead of waiting for approval. That trade puts the weight on undo, so: - removeBullet deletes only an exact-match bullet, first occurrence — a delete that quietly took out a line the user reworded would be worse than one that no-ops. - Deleting tombstones the entry in the same file propose_memory already checks, so an auto-add can't resurrect what was just removed. - The removal is attributed to the user in the file history, so the trail shows both the add and the undo. One record, one resolution: entries live in recent.jsonl until acknowledged or deleted *anywhere*, so acting in chat clears the Settings card and vice versa. Unreviewed entries age out after a week so the section can't become a chore. Also sweeps the copy that promised consent-before-write, which would otherwise now be a lie: the toggle description, topics hint, preamble reader rules, the server's tool response, and three of Berdy's rules.
The Use memory and About you descriptions read as two attempts at the same paragraph, so each now answers a different question: what memory is (and where it lives) up top, then what makes the spine file specific (the one every agent reads in every chat). Also: - Drops 'Berdy fills this in over time' — the noticer runs on every conversation regardless of agent and propose_memory is available to any agent with the tools, so naming Berdy implied a gatekeeper that doesn't exist. Berdy stays in the empty-state hint, where it's a real shortcut. - Fixes a stale consent promise the auto-add change missed: the empty state still said 'Nothing is added without your say-so,' which a brand new user reads before their file even exists. - Corrects the template's topics note. It said topic files sit 'right next to this one,' but since namespacing they live in topics/ — someone following that literally would look in the wrong place. Example filenames now match the actual vocabulary (home.md, social.md). - Trades every em dash in the Memory strings for a colon, period, or comma, and retunes the Topics hint for its spot beside Add topic.
Chat: added memories announce as toasts instead of inline cards, per design feedback. Follows CompletionNotificationToast — the app's existing two-action pattern for 'something happened, here's how to respond' — with Delete as the secondary action and OK as primary. Missing the toast costs nothing: unresolved entries stay in Settings → Memory behind the nav badge, and acting in either place clears both since they read one recent.jsonl. A shown-set keeps the 5s poll from re-toasting the same entry. This also lets ToolChainCards go back to treating propose_memory as an ordinary tool call, removing the hoisted- card machinery that existed only so cards could survive chain collapse. Settings, from testing feedback: - The rule inside 'Added to memory' was landing between the description and the cards, because divide-y treats a loose <p> as a row. The description and cards are now one unit with the rule below the section, which is the boundary that matters: the whole block appears and disappears with context. - Topics' description and Add topic move up under the heading with a rule beneath them, so Add topic sits on the other side of a line from the View buttons instead of reading as another topic row. Its pr-4 matches SettingsRow's own right padding so the buttons share a right edge. The 'New topic' subhead is gone; its description labels the naming row. - Delete and OK were identical ghost buttons, which gave no signal about which one changes a file. Delete is now destructive-ghost, OK is outline, both sized to match the View buttons.
Two stale lines the last rebase preserved because main edited elsewhere in the same file: - 'Nothing gets saved without their okay' predates auto-add. Memory is written immediately now, so the honest version is that anything saved is shown right away with a delete button. - Berdy described the disclosure as a card in the chat; it's a toast. Also adds pronouns to the About me hint, since it's exactly the kind of thing you'd rather state once than repeat.
block/me.md now has a normative spec (PROTOCOL.md, HOST.md) with
black-box conformance tests. Two of its requirements were cheap to meet
and make us interoperable, so they're worth doing before review:
Visible proposals/ instead of hidden .proposals/. The contract requires
a proposal to be 'inspectable content in the store's proposal area — not
host-private state — so that any other conforming host, or the person
with a text editor, can see and decide it.' A dotfolder reads as Berd's
business rather than the person's. Proposal records also now carry the
originating host, which the contract asks for alongside agent identity.
policy.json mirrors the memory switch into the store. Ours lived only in
Berd's app preferences, which is invisible to anything else serving the
same ~/.me/; the protocol puts policy in the store so every host honors
one decision. Berd writes it on toggle and reads it on load, so turning
memory off in another tool (or by hand) is respected here. No policy file
means no opinion, and Berd's own preference stands. Unknown keys survive
a round trip, since another host may add its own.
The directory rename needs a migration for one reason: dropping
dismissed.jsonl would let previously deleted memories be re-added, which
is the single regression the delete guarantee can't afford. It appends
rather than overwrites, leaves the old files in place, and latches after
one run.
Still deliberately non-conforming on the pen test: auto-add writes from
agent inference, which HOST.md forbids ('applying a proposal MUST require
an affirmative act'). That's the product decision from design review, not
an oversight, and it's a conversation with David rather than a fix.
Written to protect tombstones that turn out not to need protecting: the only store that ever had the hidden .proposals/ directory is one dev machine, and its contents were test data. Deleting it now, while the population is known to be zero real users, is better than leaving migration code nobody can confidently remove later.
The trail already stored everything; the metadata was written wrong. Every change committed as 'Entry approved in chat' — including deletions — so the log couldn't answer the question a person actually asks of it: did something I deleted come back? Actor and operation were conflated in one 'source' string. Split them: the author says who, the subject says what. Remove: Prefers aisle seats. You (deleted in Berd) Add: Prefers aisle seats. noticer (recorded in chat) Memory turned off You (changed the switch) Also fixes a line that went stale with auto-add: agents 'recorded' entries, they didn't get them 'approved'. And policy changes now land in the trail at all, which they didn't before — turning memory off is the highest-stakes change in the store and it was invisible. Adds a collapsed history at the bottom of Settings → Memory over the existing list_me_history command, which was built and unused. Quiet by design: nobody opens settings to read a changelog, and the answers are wanted occasionally. No new storage. PROVENANCE.md in block/me.md is explicitly non-normative and leaves the mechanism unspecified, so git stays the record and a second event log would only be a way for the two to drift.
Naming a location and then offering a separate 'Go to file' said the same thing twice, and the path is the part a person recognizes. One shared StorePathLink now handles every path in the feature, so they all behave the same way: click the path, the folder opens. Moves the location up to the toggle description, where it's visible whether or not a file exists yet, and drops it from under About you — repeating it per document was the redundancy. The empty state and the off banner link to the folder too; 'your files are untouched' reads better when you can go look. The history is the exception. It's a git object database, so calling it plain text would be false and linking it would open a folder nobody can read. It says how it's stored instead, which tells a git user what to do and everyone else that the answer is in Berd. Retires three strings (me.path, me.reveal, me.offBanner.link) and tightens the toggle description, which described the files as plain text right before the sentence that now says so.
Turning memory on created ~/.me/ but not me.md, so the page still asked for a file while the folder already existed. The folder was a side effect of writing policy.json, which creates parent directories; nothing created the spine. Seed it in both places a person can arrive with memory on: the toggle, and the first visit (memory defaults to on, so most people never touch the switch and would have kept seeing the create button). createMeFile is idempotent, so neither path can overwrite an existing file. This also matches what the rest of the system already does. Agents create the spine silently the moment they save anything — that was the fix for a first preference being unsaveable — so asking permission in the one place a person is looking was the odd behavior, not the seeding. The create button stays as the recovery path if a seed fails. History section polish alongside it: its header now matches the Topics header exactly (same alignment, gap, and no width cap), which is why the two descriptions were breaking at different words. The button reuses the topics' View/Close strings instead of a bespoke pair, holds a stable width so the description keeps one break point through the toggle, and no longer draws a row divider between the description and the opened log.
The off state was an Alert box with a bold title and a trailing ~/.me link. Alert is the wrong component for it — no other settings page uses one for a disabled state, and a warning box implies something is wrong when turning memory off is a legitimate choice. The link also repeated the one in the description directly above it. Both the off state and the missing-file state now sit in the same gray card the documents, added-memory entries and history log already use, so they read as part of the page rather than as exceptions to it. The off copy folds 'your files are untouched' into the sentence that lost the title, and the missing-file hint is down to 'No file yet.' beside its button — the toggle description above already covers what memory is and where it lives. The missing-file state is also nearly unreachable now that the store seeds itself; it stays as the recovery path if a seed fails.
Four places still described the pre-auto-add design, and two of them are
text models read every session: the MCP extension description ('Proposals
are reviewed by the user; nothing saves without their okay') and
propose_memory's own description ('Nothing is saved by this call: the user
reviews every proposal in Berd and decides').
An agent told nothing saves without approval will describe memory that way
to the user, which is worse than saying nothing — the user is told to expect
a decision that never comes. All four now say what actually happens: Berd
saves it, shows what was added, and gives them a delete button.
The structural claim is unchanged and still worth stating, so the module doc
keeps it in accurate form: propose_memory never writes a memory file itself,
so no agent can save something the user is never shown.
UI pass over Settings → Memory, keeping behavior intact:
- Unify action sizing: Add topic/View/Refresh all use xs buttons; the
Preview/Edit tab triggers match that height
- Topics and History become expandable rows (whole row clickable,
ghost chevron) instead of View/Close text buttons
- Topics header becomes a standard SettingsRow ('Add topic' + Add)
- History log renders as plain divided rows instead of an inset card
- Document preview typography: sentence-case section titles, tighter
heading-to-body spacing, wider paragraph spacing, body-colored
bullets, pl-4 list indent
- Remove stray section divider under the memory toggle row
- Spacing: 44px between the About you description and document block
One edge case: a missing (or hand-emptied) me.md now shows the starter
template as the document instead of a blank card with a create button;
the file is created on first save. The normal path — toggling memory on
seeds the file — is unchanged.
Lauren found that memories saved through propose_memory never toast. The noticer runs in the renderer and stamps the session on each candidate, so its entries surface in the chat that produced them. The MCP server can't: it's a separate process and the protocol carries no session identity, so its entries land with sessionId null, match no chat, and were disclosed only by the Settings badge. That inverted the intent — the explicit path got less disclosure than the ambient one, when an agent deliberately saving something is the case that most deserves a toast. Null-session entries now surface in the open chat. Threading session identity into the server would be the thorough fix, but it means inventing protocol the server doesn't have; claiming those entries for the chat you're looking at is right in the common case and renderer-only. With several chats open an entry can toast in the wrong one — the entry itself is still correct, and Settings → Memory remains the full list. Also removes me.emptyHint, orphaned by Lauren's change to show the starter template instead of an empty card.
Everything guarding memory content was a sentence in a prompt. That is the
right weight for preferences — a fact recorded in error is a nuisance and
undo covers it — but it is not enough for secrets, because undo does not
undo them. A saved credential is also published into the agent files other
tools read and committed to the store's history, so deleting the entry
leaves the text in places the user believes they cleared.
So the block is code, at the one funnel both doors pass through:
- Known token shapes (OpenAI, GitHub, Slack, AWS, Google, GitLab, npm,
Shopify, SendGrid, Square, JWTs, PEM private keys)
- Labelled secrets, when the value looks like a credential rather than
prose — so 'uses 1Password' and 'ask before rotating my API key' pass
- Short numeric secrets (PIN, CVV, OTP, account and routing numbers)
- High-entropy opaque blobs, label or not: no memory entry about a person
needs a 40-character random string
Deliberately biased toward rejecting a legitimate entry over admitting a
secret, and refusals are logged rather than silent.
Prompts now say it too, in both doors: the noticer's extraction rules and
propose_memory's description. The template says it to the person, since
people hand-write this file: 'Don't add passwords or credentials here. This
file is read by every agent.'
Also renames Delete to Remove on the added-memory cards and toast, with the
description Lauren and Clay settled on ('Berd found these themes from
recent chats. Confirm or remove any memories.').
The starter file still opened with 'nothing is added without your say-so'. That went stale when auto-add shipped, and I swept it out of the UI, both prompts, the tool descriptions and Berdy's rules but missed the template — the worst place to leave it, since it is the first sentence a person reads in their own file and it promises a review step that does not exist. Now: 'anything they add shows up in Settings → Memory where you can remove it', which is both true and more useful — it names where to look.
'How to work with me', 'Preferences' and 'Standing rules' were three names
for one thing — instructions about how an agent should behave. They differed
only by force ('I like bullets' / 'always use bullets' / 'never send without
drafting'), and force is what Boundaries is already for. So a person filling
this in had to guess which of three buckets a rule belonged to, and the
answer depended on how they happened to word it.
Now: About me (who you are), Preferences (how to behave), Boundaries (when
to stop). One binary question decides where anything goes — is this a limit?
Also trims every hint to a line or two. The template went from 38 lines to
25; nine paragraphs of guidance read as a form to fill in, which is the
opposite of what a sparse file wants.
'## Preferences' surviving means the spine write target still lands in a
real section, and nothing in the code or prompts named the removed
headings — agents read whatever headings the file has.
Matches what Clay put in his own file. The leading slash reads as a folder rather than a stray word, and the lowercase name matches the directory the code actually creates at ~/.me/topics/.
Two problems, one behind the other.
Every hand-edit read 'Edit' in the history, because saveMeFile and saveTopic
know the document rather than the entry and passed no summary. So the trail
was least informative for the changes a person made deliberately — delete a
line and the history couldn't tell you which one, even though the text stays
recoverable in the commit.
They now diff before against after and name the change the way the agent
paths do: 'Remove: Git branch names…', 'Add: …', 'Change: …', or counts for
larger edits. Content lines only — rewording an italic hint changes nothing
an agent reads, so it stays a plain 'Edit'.
That makes the second problem visible and therefore fixable. Removed text
lives on in the trail, which REVOCATION.md names directly: provenance must
not become a way to reconstruct deleted personal context. Clear history is
the answer — an outline destructive button at the top of the opened log,
where the document panels put Preview/Edit, so it only appears once the log
it affects is open.
Deliberately whole-trail rather than per-entry: git can't drop one commit
without rewriting every commit after it, so a granular purge means rebuilding
history and risking corruption on failure, to serve a need ('this shouldn't
be recoverable') that clearing satisfies outright.
The blast radius is narrow, and tested as such: the memory files survive, and
proposals/dismissed.jsonl survives — so entries the user removed still can't
be re-proposed, which is what the confirm dialog promises. A third test pins
that the trail never tracks the proposals queue, since tombstones carry the
text of removed entries and tracking them would put it back into history.
The log scrolls at max-h-80, matching the trusted-domains list in Security.
