Create or update a memory. Provide an id to update an existing memory. Memories are persistent across sessions and searchable. Write content that is specific, front-loads key information, and covers one concept per entry.

Search memories using BM25 ranking. Returns snippets (first ~150 chars), not full content. Use memory_recall to fetch full content for specific results. Scope searches with namespace and tags for better relevance.

Fetch full content for specific memory IDs. Use after memory_search to retrieve complete entries for the most relevant results. Only recall what you actually need.

Soft-delete a memory by ID. The entry is excluded from future searches. Requires the namespace where the memory is stored.

List all available namespaces with entry counts. Use this to discover what domains of knowledge exist before searching.
