Extract and save the Key Learnings items a subagent ended with, in any of the twelve languages Leteo writes memories in. Each becomes a memory of its own, filed under the tool that produced it.

Persist a semantic verdict between two observation IDs. Semantic not_conflict is a successful no-op.

Get pinned and recent observations plus the recent sessions and user prompts of a project. Answers about the current project unless you pass a project or all_projects. Long bodies come back as a 400-character preview marked content_truncated; read one in full with mem_get_observation.

Detect the current project without failing on ambiguous or invalid project context.

Delete an observation by ID. Soft-delete by default; hard_delete permanently removes it.

Run read-only SQLite, FTS, foreign-key, and mutation-journal diagnostics.

Get one complete observation by its numeric identifier, with its full body — unlike mem_search and mem_context, which preview it. Reads state: a memory that has been deleted is still returned here and says so.

Record a manual verdict on a pending relation surfaced by mem_save. Manual not_conflict verdicts are persisted. Reason and evidence each come back as a 400-character preview marked reason_truncated or evidence_truncated.

Merge comma-separated project name variants into one canonical project.

Pin a local observation so it appears before recent observations in memory context.

List observations due for review or mark one reviewed. Actions: list, mark_reviewed. Bodies come back as a 400-character preview marked content_truncated; read one in full with mem_get_observation.

Save an observation to persistent memory. Without session_id, uses a stable manual-save session for the detected project.

Save a user prompt in an existing session. The prompt comes back as a 400-character preview marked content_truncated; keep the sync_id to link a later save to it.

Search persistent observations by full-text query and optional filters. Answers about the current project unless you pass a project or all_projects. Long bodies come back as a 400-character preview marked content_truncated; read one in full with mem_get_observation.

End an existing memory session and optionally attach a summary. The session comes back with its summary as a 400-character preview marked summary_truncated.

Create a memory session, or return it unchanged if its identifier exists.

Save a structured end-of-session summary as persistent memory.

Get aggregate memory store statistics. Takes no arguments and counts the whole store; for one project's counts call mem_doctor with that project.

Suggest a stable topic_key for observation upserts.

Show chronological context around a specific observation. Bodies come back as a 400-character preview marked content_truncated; read one in full with mem_get_observation.

Unpin a local observation so it returns to normal recency order.

Revise a stored memory. Fields left out keep their current value. The memory comes back as a 400-character preview marked content_truncated; read one in full with mem_get_observation.
