Read-only. Search or list curated memories: query is optional for standard search, while project/type/branch and visibility flags filter results. Optional task_intent/role/risk/token_budget/include_superseded compiles a GH-934 RetrievalPlan, applies its search/rerank/fallback policy, and returns retrieval_plan audit metadata. Returns a compact JSON object with results, source='memory', pagination, and next_step for get_observations(ids, source); limit defaults to 20 and offset to 0. Use current_state when an exact stable state_key is known, timeline for chronological observation context, and search_raw for literal chat recall. explain and multi_hop each require a non-blank query, and explain cannot be combined with multi_hop=true. Invalid combinations or curated-search database failures return a tool error; an automatic raw-archive fallback failure preserves the curated results and adds raw_hits_error to the successful response.

Save a memory for future sessions. MUST be called after: (1) architecture decisions — record what was chosen, why, and what was rejected, (2) bug fixes with root cause — record symptom, root cause, fix, and prevention, (3) important discoveries — record finding and its implications, (4) user preferences — record preference and reasoning. Use topic_key for cross-session dedup (same project+topic_key updates existing memory). By default also writes a local markdown backup.

Experimental Context Bundle v1 compiler. Requires schema_version=1 and a non-blank task. Returns a policy-bounded, source-attributed ContextBundle with a complete selection/drop audit; project is explicit or derived from cwd, and role/risk/token budget have deterministic defaults. Historical as_of_epoch pins and include_superseded=true fail loudly until the canonical loader supports them. This reuses the production SessionStart canonical loader, performs no foreground LLM or network call, and returns canonical load failures as a blocked audited bundle. Its poisoning safety check may quarantine unsafe persisted rows, so callers must not treat it as side-effect-free. The JSON shape is versioned but remains experimental.

Look up git commit metadata and linked memory sessions by full or short SHA. Its poisoning gate may quarantine the newest eligible unsafe linked session summary. The response separates git metadata from memory-derived summaries so missing links are not inferred.

List git commits linked to a content session ID or remem memory session ID. Its poisoning gate may quarantine the newest eligible unsafe linked session summary. Returns link evidence plus git metadata; it does not guess commit intent when no link exists.

Auditably delete, reject, or mark curated memories stale. Use dry_run=true first to preview affected IDs and their current versions. Non-dry-run mutations require confirm_destructive=true, an explicit reason, and expected_versions containing every target ID. This never deletes raw archive data.

Mutates one existing workstream by id. At least one of status, next_action, or blockers is required; omitted fields remain unchanged. status accepts only active, paused, completed, or abandoned. Returns a JSON object with id and updated, where updated=false means no row matched. Use workstreams to list/read rows first. This tool does not create or delete workstreams; an empty update, an unknown status, or a database failure returns a tool error.

Read-only. Resolve one stable state_key to a JSON object with status=current, no_current, not_found, ambiguous, or unresolved_conflict, plus answer, compact history, and why edges. state_key must be non-blank; project/owner/type/as_of filters narrow the resolution. Use this instead of search when the durable key is known; use timeline for chronological observation context. Invalid input or database failures return a tool error.

Assemble task-aware user context from safe claims, profile summary, repo memories, requested current-state keys, workstreams, and recent sessions. Its poisoning gate may quarantine an unsafe legacy or session summary. Requires a non-blank query and an explicit project or cwd scope. Returns a compact source-attributed JSON object with included items, dropped items, reason codes, and budget metadata. Use search for exhaustive memory matches and current_state for one exact stable key; this tool selects a bounded context bundle instead. Invalid or missing scope input and database failures return a tool error.

Fetch full details for explicit IDs and record last-accessed metadata for returned memory or observation rows. Use after search, not for discovery; prompt-time anchors may also direct this exact lookup. Pass selected IDs and the exact source from the result. source defaults to 'memory'; source='memory' returns curated memory details and requires its access update to succeed, source='observation' returns current extracted observations and records its access update best-effort (a failed update is logged but details still return), and source='session_summary' returns exact safe session-summary rows without confusing their IDs with observation IDs. Unsupported sources, any missing requested ID, detail-read failures, or memory access-update failures return a tool error.

List sessions with raw archive messages inside a time window, grouped by (source_root, host, project, session_id) with a stable session_ref, content_hash, first/last message epoch, message count, and optional role=user message samples. Unresolved or conflicted provenance is skipped and reported in excluded_legacy_identities; latest fills at most that many newest healthy sessions and does not spend slots on skipped rows. Use for recap-style summaries of what happened in a period. Output fields match remem raw sessions --json.

Read-only. Return a JSON array of observations before and after one center point; provide anchor or query, and anchor takes precedence when both are set. depth_before and depth_after default to 5, and project limits both anchor lookup and results. Use this for local chronological context around an observation; use timeline_report for an aggregated project report, search for curated memories, or current_state for a stable fact. Missing anchors/queries, no query match, or database failures return a tool error.

Search the raw archive (every user/assistant turn captured by the Stop hook). Use this when search returns no curated match or you need to recall a literal phrase from past chats. Returns the untreated conversation content — expect noise. The raw archive is what guarantees 'what was said remains searchable' even when summarize/promote skip a turn.

Read-only. Generate an aggregated Markdown report for the required project with activity history, type distribution, and Token ROI analysis. full defaults to false for the compact report; full=true adds the detailed timeline and monthly breakdown. Use this for project-level reporting, not observation lookup; use timeline for chronological context around one observation. Database failures return a tool error.

Read-only. List existing high-level workstreams for a required project, optionally filtered by status=active, paused, completed, or abandoned. Returns a JSON array with each workstream's status, progress, next action, blockers, and timestamps. Use update_workstream to mutate an existing row; this tool does not create, update, or delete workstreams. A missing project or database failure returns a tool error.
