Tools (11)

check_version

"Did anything change?" — pass an entity name + cached hash, get back yes/no. No embedding computation, pure metadata.

consolidate

Find clusters of similar/duplicate memories, detect near-duplicate entities, surface contradictions, or run sleep mode for batch lifecycle analysis (compress/prune/refresh)

context

Get everything about a topic — observations, relationships, related entities. Includes versionhash.

export

Export as CLAUDE.md context file, readable markdown, JSON, wire format, or Obsidian vault

forget

Permanently delete a memory or entity (secure deletion)

merge

Merge multiple observations into one (atomic consolidation). Returns versionhash.

merge_entities

Merge multiple entities into one — moves all data, deletes sources. Returns versionhash.

onboard

Bootstrap memory from a new AI session. Returns structured extraction instructions the AI follows to capture user context.

recall

Search memories by semantic similarity + keyword match. Filter by type, kind, since. Use spread: true to follow relationships and discover connected memories. Includes versionhash per entity in all formats.

remember

Store a fact, preference, or piece of context. Optional kind classification (fact, decision, question, preference, or custom) and importance weighting. Reports overlapping observations so the AI can consolidate incrementally. Returns versionhash for cache invalidation.

update

Replace an existing observation with new content. Returns versionhash.
