Memory Onboard

/memory-onboard — repo-aware onboarding for memory

This skill is the way to seed a repo with lore. It earns its keep by reading the repo first (README, ADRs, recent commits, deprecation markers, in-flight migrations) so the proposed drafts are specific to this codebase, with source citations — rather than inventing memory or mechanically chunking every bullet in the docs (which produces mostly noise and floods the review queue).

Output: DRAFT records with source citations, plus optional absence markers and boundary edges. Everything lands in memory review for a human to ratify — the skill never promotes its own records.

Hard rules

1. Every lore record this skill produces is a DRAFT. Call suggest_lore (or report_conflict for counter-claims — also drafts), never any approval path. The human reviews with memory review. Exception: record_absence does NOT create a draft — it records a self-expiring "we checked, no policy" marker. Different primitive, different gate (see rule 6).
2. Every draft carries the tag induction so it can be filtered later. Layer topic-specific extras as appropriate (security, conventions, migrations, incident-lessons, invariants, etc.). report_conflict counter-drafts are auto-tagged conflict-report by the server.
3. Cite sources in the body. When a draft comes from a file or commit, include a one-line reference at the top of the body — e.g. Source: README.md L42–55 or Source: commit abc1234 "migrate accounts → organisations". This is the trust signal a reviewer needs.
4. Never put secrets, credentials, personal data, regulated data, or anything that looks like a token into any lore record. If a candidate item contains something like that, skip it and tell the user why.
5. Skip the obvious. "We use TypeScript", "run the tests before committing", and other things a model already knows about a typical codebase belong in CLAUDE.md (or nowhere), not in lore. Aim for non-obvious, high-consequence knowledge.
6. Use record_absence sparingly. If the user explicitly confirms "we don't have a policy on X yet, and that's intentional", that's a legitimate absence marker — call record_absence({ query: "<topic>", reason: "<why no policy>", repo: <repo> }). Don't infer absence from "I didn't find anything in the README"; the user has to confirm it. Markers self-expire (14 days default) so they fade automatically if the team takes a stance later.
7. Use report_conflict when you find a contradiction, not when you find a duplicate. If search_lore returns an existing record and the source-of-truth you just read disagrees with it (e.g. README says "Argon2id", existing lore says "scrypt"), that's a report_conflict moment. If the existing record just covers the same topic without contradicting, leave it alone — possibleConflicts in search results handles benign overlap.

Procedure

Follow these steps in order. Confirm with the user as the comments indicate.

Step 1 — confirm scope

Detect the current repo's short name (from git config --get remote.origin.url or, failing that, from the working directory name). Confirm with the user:

"I'll onboard <repo-name> to memory. Anything I should add to that, or remove? (e.g. payments-svc, auth-svc for cross-repo notes)"

Capture the final repos array — every draft created in this session will carry it.

Step 2 — survey the repo

Read these sources, in this order. Stop short of full-file reads when you can — skim for signals.

1. CLAUDE.md / AGENTS.md / .claude/CLAUDE.md (any of these agent-instruction files): highest-priority source. These already contain content the team has hand-curated for agents — sections like "Things That Catch People Out", "Conventions", "Gotchas", "Architectural decisions", "Migrations", and similar are designed for exactly the kind of content memory captures. Treat each H2/H3 subsection (or each bullet under such a heading) as a candidate. Your job is to triage durability — not just transcribe the file verbatim. If a bullet reads as task-specific or transient, skip it; if it reads as "this is how things are here and will be in six months", capture it.
2. README.md — flag anything mentioning: "deprecated", "DO NOT USE", "WARNING", "legacy", "see also ", "incident", architectural choices, naming conventions, env vars with surprising defaults.
3. docs/, docs/adrs/, docs/architecture/, ADRs/, decisions/, .architecture/ — if any exist, scan titles and final-decision sections. ADRs are the cleanest source of "decisions that aren't obvious from code".
4. MIGRATIONS.md / migrations/ / db/migrations/ — in-flight migrations are gold for lore. Look for "TODO", recent file dates, companion code that handles both old + new schemas.
5. Top-level package.json / pyproject.toml / go.mod / Cargo.toml — service name, peer-repo dependencies that suggest cross-repo conventions worth capturing.
6. git log --oneline -50 — recent commit subjects often hint at: in-flight migrations ("migrate X to Y"), deprecations ("remove legacy Z"), incident fixes ("fix INC-NNN: …"), policy decisions.
7. Grep for // DEPRECATED, // TODO: remove, // WARNING:, // HACK: — these often mark non-obvious project knowledge.

Step 3 — surface candidate drafts

Build a list of 5–10 candidate drafts grounded in what you found. Present them to the user as a numbered list with the source citation:

Found these candidate items. Want me to draft any of them as lore?

1. Don't touch legacy/auth.ts except for security fixes. Use requireSession() for new auth gates. (Source: README.md L42–55; grep finds 12 active call sites of requireSession.)
2. In-flight migration: accounts → organisations. New code uses org_id; reporting still joins on account_id. (Source: commit a4f12c0 + migrations/0017_accounts_to_orgs.sql.)
3. Webhook retries cap at 2h backoff to avoid downstream DoS. (Source: docs/adrs/0009-webhook-retry-cap.md, INC-411.) …

Reply with the numbers to draft (e.g. 1, 3, 5) or skip with none. I can also propose more items if I missed anything.

Skip items that are:

• generic programming advice the model already knows
• obvious from a single file's contents
• task-specific or session-specific
• anything containing apparent secrets / PII / regulated data
• already covered by an existing lore record (run search_lore for near-duplicate titles before proposing)

Step 4 — draft via suggest_lore

For each item the user picks, call suggest_lore with this shape:

suggest_lore({
  title: "<short title — what is the rule / fact?>",
  summary: "<one-paragraph summary, stands alone>",
  body: "Source: <file/line or commit sha or doc path>\n\n<full detail / reasoning / evidence>\n\n(onboarded via /memory-onboard, <iso date>)",
  repos: <array confirmed in Step 1>,
  tags: ["induction", <topic-specific extras>],
  source: <PR/ADR/incident URL if you found one>,
  confidence: <"medium" if source URL is present, else "low">,
  team: <if obvious from CODEOWNERS or similar>
})

Drafts can't claim high confidence regardless — that invariant is enforced server-side. Don't try.

After each call, note the returned id and any possibleDuplicates the server flagged. If possibleDuplicateCount > 0 or possibleDuplicates is non-empty, tell the user before continuing:

"Draft <new-id> created. Memory flagged 2 possible duplicates: <id1>, <id2>. Worth reviewing those alongside this one."

Step 5 — wrap up

When the user is done picking, output a final summary:

Created N drafts in <repo>:

• <id1>
• <id2> …

Counter-drafts (from report_conflict, if any):

• <id3> challenges <existingId>

Absence markers (from record_absence, if any):

• <query> — <reason> (expires in 14 days)

Next steps:

• memory review — interactive triage of the drafts
• memory hooks install — opt-in: a Stop-hook nudges you to review pending drafts at session end so they don't rot in the queue (one-time-per-session, never nags)

Drafts are invisible to default search until approved. Absence markers surface only on zero-hit searches matching the same normalised query.

If the user wants to keep iterating, loop back to Step 3 with a different angle (e.g. "now let's look at the test suite for authoritative-checks lore", or "let's scan for incident-lesson signals in the issues tracker").

Step 6 — (when invoked mid/end-of-session) ground in THIS session's work

The repo survey in Step 2 is a cold read. The higher-signal source, when you have it, is the work the current session just did — what you learned debugging, migrating, or fixing something here over the last hour is exactly the non-obvious knowledge the next agent will lack.

If this skill is invoked after real work in the session (not a first-touch cold start), before wrapping up ask yourself:

1. Did I hit a gotcha that wasted time and will bite again? (a non-obvious constraint, a surprising default, an ordering rule)
2. Did I discover a convention by reading code that isn't written down? (naming, auth, timezone, data-modelling)
3. Did I steer away from a deprecated pattern after spotting it?
4. Did I learn why a past decision was made that the code alone doesn't explain?

For each "yes", propose it as a candidate draft (same numbered-list + confirm flow as Step 3) with the session as the citation — e.g. Source: discovered while implementing <task> this session. Only durable, project-specific findings; skip anything transient or already-obvious (same Step 3 skip rules apply).

When a finding is already captured in a commit you made this session, tell the user the cheaper path instead of re-drafting it by hand:

"I committed the rationale in a4f12c0. You can draft that straight from the message with memory suggest --from-commit a4f12c0 (it auto-derives the commit permalink as the source) rather than me retyping it."

This session-grounded pass is the difference between transcribing a repo and capturing what was actually learned working in it.

Step 7 — (optional) map cross-repo boundaries

While surveying the repo (Step 2) you'll often spot integration points: an event this service publishes, an endpoint it serves, a queue or table another team owns. These are boundary edges — the substrate of the cross-repo impact map.

• When you find a producer/consumer relationship, check the map first with find_dependents({ contract }), then record what's missing with declare_boundary({ repo, contract, role: "provides" | "consumes", kind?, detail?, source? }). Like lore, edges land as drafts — the human ratifies via memory boundary review.
• Use provides when this repo OWNS / produces the contract; consumes when it depends on one owned elsewhere.
• Don't invent edges. Only declare integration points you actually saw in code/config (publish calls, route definitions, client calls, schema references). Cite the evidence in detail or source.

This is how the "change this contract, what does it affect?" query gets populated — one onboarding at a time, per repo, aggregated via sync.

A note on search results

When you call search_lore during onboarding to check for near-duplicates, the server ranks hits by relevance adjusted for trust (sourced, higher-confidence, non-stale records first), so the top hits are the ones most worth comparing against. If a response includes a truncated: { shown, total } block, more records matched than were returned — narrow the query or raise limit before concluding a topic is uncovered.

Out of scope for this skill

• Don't promote, deprecate, or supersede records. Those are CLI-only by design.
• Don't bulk-import existing docs as lore. Onboarding is selective — the value is judgement about what's durable and non-obvious, not volume. Transcribing every bullet of a doc floods the review queue with noise and degrades the trust gate. Propose a focused set; let the human ratify via memory review.
• Don't enable restricted records (includeRestricted / setting restricted: true). If the user wants restricted lore, they author it via the CLI with memory add --restricted.
• Don't claim contradictions you can't prove. If search_lore returns existing records that overlap (possibleConflicts populated), that's the runtime overlap heuristic — surface it but let the human decide. Only call report_conflict when a source-of-truth you just read explicitly disagrees with the existing record (see Hard rule 7).
• Don't blanket-record absences. A record_absence marker is only warranted when the user confirms "the team has intentionally not taken a stance on X". Inferring absence from "I didn't find anything" would seed wrong markers that mislead the next agent.
• Don't install the Stop-hook on the user's behalf. Mention it exists at wrap-up so they can opt in (memory hooks install), but installing it silently changes their .claude/settings.json — that's their decision.
