Tools (7)

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

capture_error
Record a failure from `tool` name, `error` text, and optional `context`, returning the stored error entry.
hypotheses
List hypothesis objects, optionally filtered by `status` (testing, graduated, or rejected).
learn
Record or reinforce one lesson from `type` (failure, pattern, gotcha, or preference), `insight`, and optional `domain` and `context`, returning the stored lesson.
recall
Search stored lessons for the substring `query` and return up to `limit` matching lesson objects, newest first.
start_brief
Return the start-of-task digest (preferences, learnings, open_hypotheses, open_units, last_checkpoint, recent_errors), taking no arguments.
stats
Return a mapping of every metabrain table name to its row count, taking no arguments.
verdict
Record `result` ("pass" or "fail") against an optional `unit` or `hypothesis` with optional `evidence`, and return the stored entry (an experiment is written when a hypothesis is in play).
