Record what you did, any choices you made, and anything you discovered. Call before committing or ending a session. The summary becomes a status post. Decisions become tracked records with rationale. Findings become blackboard entries visible to future agents. Scope is auto-inferred from git diff if omitted.

Run periodic maintenance on Twining stores. Preview by default (dry run). Archives old entries, removes duplicates, surfaces stale decisions and dangling warnings, prunes orphaned graph entities, and rotates old metrics. Pass staleness_review: true to also flag entries whose scope/files/branch are gone. Pass execute: true to apply changes.

Archive a list of stale items by ID — typically the candidate IDs returned by twining_housekeeping with staleness_review: true. Decisions move to status "archived" (excluded from assemble/why). Blackboard entries are dismissed. Items remain on disk with provenance preserved.

Share a finding, warning, need, or status update with other agents. Post a 'status' entry before ending each session. Does NOT accept entry_type 'decision' — use twining_decide instead.

Before modifying a file, check what decisions constrain it. Shows rationale and alternatives so you don't contradict prior choices.

Your FIRST call every session. Returns a briefing with decisions to respect, warnings to address, and handoff context from previous agents. Call BEFORE reading code or making changes.

Overall health check of the Twining state. Shows blackboard entry count, decision counts, graph entity/relation counts, actionable warnings, and a human-readable summary. Note: twining_assemble now includes a status summary — use this only when you need the full detailed health check.

Archive old blackboard entries. Moves entries older than a cutoff timestamp to an archive file, preserving decision entries. Optionally posts a summary finding.

Add or update a knowledge graph entity. Uses upsert semantics: if an entity with the same name and type exists, its properties are merged and updated. Returns the entity ID.

Add a relation between two knowledge graph entities. Source and target can be entity IDs or names. Returns an error for ambiguous name matches.

Traverse the knowledge graph from an entity, returning neighbors up to a given depth (max 3). Supports filtering by relation type. Useful for understanding how entities connect.

Search the knowledge graph for entities by name or property substring match. Case-insensitive. Returns matching entities with their properties.

Remove orphaned knowledge graph entities that have no relations. Use this to clean up stale or disconnected entities. Optionally filter by entity type to only prune certain kinds.
