version: "1.0.1" name: recall description: "Answers a question from what is already stored in the user's knowledge bases, citing the page behind every claim and naming the gaps honestly. Use when asked 'what do I know about X', 'where do things stand with Y', when another capability needs stored user context, or before starting any research — check the bases first. Do NOT use to file new content (that is kb-capture) or to explain how the base system itself works (that is kb)."

recall

Every claim cites a `[[path]]`, and a miss is stated out loud — never answer from training data while implying it came from the bases. The searching agent is you, the asking agent.

1. Pick bases. An explicit mention wins ("in my work base"). Otherwise route the question

yourself against the registry — read it directly at $AOS_REGISTRY, else <aos_home>/.aos/kb-registry.yaml, since no verb lists bases — where each entry's purpose is the rubric. Candidates are cheap; read deeply only in the top-ranked base or two, and pass --base <name> on every command so you know which one answered.

1. Find candidates with two engines, combined freely.

• Agentic navigation (default): index.md's one-liners as the table of contents →

follow [[wikilinks]] → grep. Best for structure-shaped questions over curated pages.

• Deterministic: kb search "<query>" (BM25; exact and alias hits flagged EXISTS),

kb find --where type=company --where tags=active (metadata), kb links <page> (backlinks and neighbours). Best for fuzzy phrasing, cross-zone needles, and _raw/'s unpromoted tail — which skeptical promotion guarantees exists and navigation cannot reach.

1. Select and read. Around five pages before going deeper; prefer wiki pages over raw

fragments; follow at most two link hops from a starting page; drop into _raw/ only to verify a source or where the wiki is silent. Honour Contested (present both sides) and verified: false (never the sole support of a conclusion).

1. Synthesize with citations. State the known gaps explicitly ("nothing on Acme's

funding after March"). On a miss, say so — and offer to capture the open question as a curation signal. Never auto-capture.

1. Offer to file back. A substantive, durable synthesis can become a page: offer it,

never file it silently. If accepted it goes through the {{skill: route}} skill, verified: false, origin: pointing at this session. On a shared base the offer lands in the queue like every other agent write.

1. Bump state — only if you are this base's state writer (agent:main by default;

confirm with kb grants check --subject <you> --verb write --path .kb/state/x.yml — any path under the zone, the check is against the glob) and an attention item was materially used: kb state bump --note <substring>. The substring must match exactly one item, and the command errors if it matches none or several — read the error and pick a longer substring rather than retrying blindly. DENIED → do not bump, and say so in your answer. kb state bump will succeed regardless, because no write verb consults the grants table; the violation only surfaces in the next weekly audit, which is why honouring the check is yours to do.

Where the harness supports sub-contexts, delegate the read-heavy traversal in step 3 to one and return only the answer plus citations — it keeps the caller's context clean. Degraded mode without the tool: the same funnel, agentic engine only.
