Save memory. This single write tool handles observations, user prompts, session summaries, and passive learning capture.

For durable observations, use kind=observation and structured content: What: [concise description] Why: [reasoning or problem] Where: [files/paths affected] Learned: [gotchas, edge cases]

Use topic_key for evolving topics that should update in-place.

Primary retrieval tool. Runs fused hybrid recall across sentence vectors, chunk vectors, keyword FTS, and knowledge-graph enrichment.

Get recent memory context from previous sessions. Shows recent sessions, user prompts, and observations to understand what was done before.

Use this at the start of a session to recover context, or when the user asks to recall past work.

Returns bounded Markdown with:

• Recent sessions (last 5 with activity)

• Recent user prompts (last 10)

• Recent observations (configurable limit)

• Memory stats (total counts)

Observation bodies are previewed by default; use mem_get(id=...) for full content.

Fetch a saved observation or prompt by ID. Use include_timeline=true when the surrounding observation chronology matters.

Project-level memory navigation. Lists projects, summarizes one project, reads graph facts, or inspects topic-key memory.

Manage the active memory session. Use action=start at session start and action=summary before ending.
