Install

Works with Claude Code, Codex, VS Code, Cursor, Windsurf, Claude Desktop. Read the repository before you give any tool access to your data.

npx agentmarket install connector/skynetcmd-m3-memory

Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

Tools (27)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

files_corpus_create
Register a new corpus with optional default overrides. `default=True` marks this corpus as the installation's default (clears the flag on any prior default in the same transaction).
files_corpus_delete
Delete a corpus's settings row. Cascade=True also deletes its file_nodes and all dependent rows — DESTRUCTIVE. Without cascade, refuses when the corpus has file_nodes.
files_corpus_get
Fetch a single corpus's settings + counts.
files_corpus_list
Enumerate corpora with row counts.
files_corpus_set
Update settings for an existing corpus. None args are no-ops. Creates the corpus_settings row if absent.
files_dedup
Scan leaf embeddings for near-duplicates. Detection only — pairs land in semantic_dedup_candidates for human review.
files_dedup_list
List near-duplicate candidate pairs with text snippets and paths.
files_dedup_review
Record a review decision: 'kept' | 'merged' | 'ignored'.
files_entity_coalesce
Detect provisional-entity coalescing candidates (quarantine noise + flag near-duplicate entities). Detection only — never merges, never auto-applies; candidates land in entity_coalesce_candidates for review. dry_run=True estimates without writing or embedding.
files_entity_coalesce_apply
Apply the reversible same_as/cluster overlay. Union of explicit candidate_uuids (reviewed 'merge' or 'unapplied' tombstone) and — if include_auto_merge — the LATEST run's 'merge' band (or resolution_run). Members are never deleted; reverse with files_entity_coalesce_unapply. WRITES the core graph: a real apply MUST pass confirm=True; dry_run=True previews without writing.
files_entity_coalesce_list
List entity-coalescing candidate pairs (name + score + band).
files_entity_coalesce_review
Record review decisions in BULK: pass a list of {uuid, action} where action is 'merge' | 'related' | 'reject' | 'defer'. Records intent only; materialize decisions with files_entity_coalesce_apply.
files_entity_coalesce_unapply
Reverse one coalescence cluster (drop edges, clear flags, strip aliases, tombstone the candidate so auto-merge won't resurrect it). Members are never deleted; re-apply via files_entity_coalesce_apply with candidate_uuids.
files_extract_pending
Drain leaves with extraction_status='pending' through the LLM extractor. Used after a queue-mode ingest. Safe to call repeatedly.
files_get
Fetch one record by UUID. Tries file_nodes then leaves.

Show 12 more tools

files_health
DB integrity + FTS5 sync check. Set rebuild=True to fix drift.
files_index
Return file-level summaries for triage. Cheap-first retrieval — no leaf content. Use BEFORE files_search.
files_ingest
Walk a directory and ingest supported files into files.db. Idempotent: same content_sha256 → no-op; changed content → new file_node version supersedes prior. Use extract_mode to opt into fact extraction; use original_path (or a <path>.m3meta.json sidecar) to point search results at a source-of-truth file when the ingested file is a conversion.
files_link_rename
Re-point an existing file_node at a new path (rename / move). NOT a supersession — content stays identical. Use this only when staleness review surfaces a rename candidate.
files_promotable
List top promotion candidates by usage-weighted heuristic score. Suggestion-only; use files_promote to actually ascend any.
files_promote
Promote (ascend) a fact / leaf / file_summary from files.db to memory.db. Source stays untouched; copy lands in memory.db with a metadata back-pointer. Idempotent.
files_promotion_list
List existing promotions. source_superseded=True surfaces promotions whose source file has since been superseded — candidates for review.
files_search
Hybrid FTS5 + vector search over leaves. Default: current versions only. Set include_history=True for time-travel.
files_staleness_review
Compare filesystem against files.db. Surfaces stale, touched-only, missing, new, failed-extraction, drifted-promotion files, and rename candidates (missing files whose content reappeared elsewhere on disk). Report-only: does not modify anything.
files_stats
Corpus-level counters: file_nodes, leaves, embed coverage.
files_watch_once
Single-pass staleness check + notification dispatch. Suitable for cron / scheduled runners. Notifications are emitted via the memory.db notifications inbox; cooldown suppresses duplicates.
save_handoff
Saves the current AI session state for another agent to resume.
