Unified search tool. Uses hybrid search (keyword + semantic + convex combination fusion) internally. Auto-strengthens memories on access (Testing Effect).

Unified memory management tool. Actions: 'get' (retrieve full node), 'purge' (irreversibly remove content/embeddings with confirm=true), 'delete' (legacy alias for purge), 'state' (get accessibility state), 'promote' (thumbs up — increases retrieval strength), 'demote' (thumbs down — decreases retrieval strength, does NOT delete), 'edit' (update content in-place, preserves FSRS state).

Unified codebase tool. Actions: 'remember_pattern' (store code pattern), 'remember_decision' (store architectural decision), 'get_context' (retrieve patterns and decisions).

Unified intention management tool. Actions: 'set' (create), 'check' (find triggered), 'update' (complete/snooze/cancel), 'list' (show intentions).

INTELLIGENT memory ingestion with Prediction Error Gating. Single mode: provide 'content' to auto-decide CREATE/UPDATE/SUPERSEDE. Batch mode: provide 'items' array (max 20) for session-end saves — each item runs the full cognitive pipeline (importance scoring, intent detection, synaptic tagging).

Index an external system into Vestige as a durable, offline, semantically-searchable index that cites back to the canonical record. GitHub: source='github', repo='owner/name' (auth via GITHUB_TOKEN env). Redmine: source='redmine', project='' (host via REDMINE_URL, auth via REDMINE_API_KEY env). Idempotent: re-running updates changed issues without duplicating; set reconcile=true to tombstone issues removed upstream.

Browse memories chronologically. Returns memories in a time range, grouped by day. Defaults to last 7 days.

View audit trail of memory changes. Per-memory: state transitions. System-wide: consolidations + recent state changes.

Combined system health and statistics. Returns status (healthy/degraded/critical/empty), full stats, FSRS preview, cognitive module health, state distribution, warnings, and recommendations.

Run FSRS-6 memory consolidation cycle. Applies decay, generates embeddings, and performs maintenance. Use when memories seem stale.

Create a SQLite database backup. Returns the backup file path.

Export memories as JSON or JSONL. Supports tag and date filters.

Garbage collect stale memories below retention threshold. Defaults to dry_run=true for safety.

Score content importance using 4-channel neuroscience model (novelty/arousal/reward/attention). Returns composite score, channel breakdown, encoding boost, and explanations.

Find duplicate and near-duplicate memory clusters using cosine similarity on embeddings. Returns clusters with suggested actions (merge/review). Use to clean up redundant memories.

Surface likely duplicate/overlapping memory clusters with confidence scores and the signals behind each (Fellegi-Sunter match/possible/non-match). Read-only — nothing is changed.

Produce a previewable MERGE plan (a diff: combined content/tags/provenance) for 2+ memories WITHOUT applying it. Returns a plan_id for apply_plan. Protected members block the merge.

Preview superseding memory A with B — bitemporal invalidation (stamps valid_until, keeps A queryable for audit) WITHOUT applying. Returns a plan_id for apply_plan.

Execute a previously-generated merge/supersede plan by id. Recorded as a reversible operation. Old memories are invalidated (never deleted). 'possible'/'non_match' plans require confirm=true.

Reverse a prior merge/supersede operation (the 'git reflog for your agent's memory'). With no operation_id, lists the reversible operation log so you can pick one.

Pin a memory so it can never be auto-merged, superseded, or garbage-collected. Pass protected=false to unpin.

Get or set the per-project merge policy: the two Fellegi-Sunter thresholds (match_threshold, possible_threshold) and auto_apply. No args returns the current policy.

Trigger memory dreaming — replays recent memories to discover hidden connections, synthesize insights, and strengthen important patterns. Returns insights, connections, and dream stats.

Graph exploration tool for memory connections. Actions: 'chain' (build reasoning path between memories), 'associations' (find related memories via spreading activation + hippocampal index), 'bridges' (find connecting memories between two nodes).

Proactive memory prediction — predicts what memories you'll need next based on context, recent activity, and learned patterns. Returns predictions, suggestions, and speculative retrievals.

Restore memories from a JSON backup file. Supports MCP wrapper format, RecallResult format, and direct memory array format.

One-call session initialization. Combines search, intentions, status, predictions, and codebase context into a single token-budgeted response. Replaces 5 separate calls at session start.

Retention dashboard. Returns avg retention, retention distribution (buckets: 0-20%, 20-40%, etc.), trend (improving/declining/stable), and recommendation. Lightweight alternative to full system_status focused on memory quality.

Subgraph export for visualization. Input: center_id or query, depth (1-3), max_nodes. Returns nodes with force-directed layout positions and edges with weights. Powers memory graph visualization.

ComposedGraph memory topology. Reads durable composition events, members, and outcome labels; returns recent/already-composed lanes, neighbors, never-composed pairs, bounty-mode lanes, and lets users label outcomes such as helpful, submitted, accepted, rejected, duplicate_risk, needs_poc, or dead_end.

Deep cognitive reasoning across memories. Combines FSRS-6 trust scoring, spreading activation, temporal supersession, dream insights, and contradiction analysis to build a complete understanding of a topic. Returns trust-scored evidence, fact evolution timeline, and a recommended answer. Use this when accuracy matters.

Alias for deep_reference. Connect the dots across memories with cognitive reasoning.

Inspect memory disagreements directly. Scans a topic or recent memories for trust-weighted contradiction pairs using the same local logic as deep_reference.

Actively suppress a memory via top-down inhibitory control (Anderson 2025 SIF + Davis Rac1). Distinct from delete: the memory persists but is inhibited from retrieval and actively decays. Each call compounds. A background Rac1 worker cascades decay to co-activated neighbors. Reversible within 24 hours via reverse=true.
