Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• diff

  What changed in memory since a given ISO date: new facts learned, beliefs revised, facts retracted. The 'what have you learned about X since Monday?' query.

• forget

  Retract a fact by id, or retract EVERYTHING from a given source_ref (provenance-based deletion: 'forget everything from that session'). Tombstoned, not erased: as_of queries before the retraction still show history; current recall never returns it.

• recall

  Retrieve relevant memories. A plain call returns current beliefs ranked by relevance × confidence × importance × recency (recency is freshened each time a fact is recalled). as_of (ISO date, e.g. '2026-06-01') returns what was believed AT THAT TIME — including facts since revised or retracted. Use as_of to answer 'what did you think before I corrected you?'. subject filters to one entity; kind filters to semantic/episodic/procedural.

• remember

  Store ONE atomic fact in long-term memory: a single assertion, ideally one sentence (aim for under 250 characters; writes over 1500 are rejected). Split compound knowledge into multiple remember calls so each piece can be revised independently later. Use for durable knowledge about the user, their projects, preferences, decisions, and environment — not transient task state. If this contradicts an existing belief, find it with recall and use revise instead. Always fill source_ref with where this came from (session, file, URL) if known. If the fact describes code you just read at a known commit,…

• revise

  Replace a belief with an updated one. The old fact is closed and linked to its successor — history is preserved, never deleted. Use when the user corrects you or circumstances change. Find the old fact's id with recall first. valid_from can backdate when the new state actually began (e.g. 'moved last month'). importance and kind are inherited from the old fact unless you override them.

• stats

  Memory database statistics: counts, top subjects, schema version, db path.

• why

  Full provenance and revision chain for a fact: where it came from, when it was learned, what it superseded, and what superseded it. Use to answer 'why do you believe that?' or to audit a belief before revising it.
