Manage graph nodes in the state graph (actions: create, update, get, remove, list, search, batch_create, batch_update, add_note). Use manage_nodes instead of manage_tasks when operating on general node types (decisions, artifacts, plans, milestones, blockers) rather than runnable task workflow states.

Returns node object, edge connections, batch results, or search matches.

Manage typed graph relationships between nodes (actions: add, remove, batch_add, link_visual). Use manage_edges instead of manage_nodes when creating or modifying relationships between existing entities rather than entity data itself.

Returns created edge record, batch count, or visual link confirmation.

Manage agent tracking sessions and multi-turn workflow attribution (actions: start, end, list, bootstrap). Use manage_sessions instead of manage_tasks when establishing agent session boundaries and tracking multi-turn workflows rather than individual work items.

Returns session record, bootstrap context snapshot, or active session listing.

Task prioritization, workflow execution, blockers, and stale task management (actions: next, complete, find_blocked, find_stale, find_blockers, find_similar_blockers, auto_prune). Use manage_tasks instead of query_graph when querying runnable tasks by priority order or resolving execution blockers.

Returns prioritized runnable tasks, blocker hierarchy, similar resolved blockers, or completion confirmation.

State checkpointing, time travel, diffing, and undo operations (actions: save, list, diff, get_state, revert, undo, get_history). Use manage_snapshots instead of manage_database when reverting state graph mutations or comparing checkpoints rather than physical database file maintenance.

Returns snapshot record, state graph diff, historical graph state, or node audit history.

Spec-Driven Development (SDD) lifecycle and workflow template generation (actions: scaffold, ingest, export, compliance, verify, decompose_feature, template). Use manage_specs instead of manage_nodes when authoring, ingesting, or verifying formal SDD specifications against acceptance criteria.

Returns specification AST, compliance matrix, verification verdict, or decomposed feature plan.

Physical SQLite database maintenance, backups, integrity checks, and Git VCS state sync (actions: backup, restore, audit, merge, branch_diff, branch_merge). Use manage_database instead of manage_snapshots when managing physical SQLite files, cross-branch merges, or database corruption audits.

Returns database backup path, foreign key integrity report, branch merge conflict report, or diff.

Export and import graph structures, issue tracker items, fine-tuning trajectories, and multimodal synergy metrics (actions: export_graph, export_issues, export_trajectories, export_joint_trajectories, export_synergy_metrics, from_tick, import_graph, import_issues, import_spec). Use manage_data instead of query_graph when bulk-transferring graph data or generating AI training datasets.

Returns serialized graph payload, trajectory dataset, synergy metrics, or import statistics.

Query graph topology, neighborhoods, dependency paths, safe read-only SQL queries, and compact System One task slices (actions: subgraph, trace, raw, natural_language, compact_slice). Use query_graph instead of get_analytics when exploring graph topology and path traversals rather than aggregated numerical metrics.

Returns subgraph nodes and edges, upstream/downstream trace path, raw SQL rows, or compact task slice.

Compute workflow metrics, velocity, burndown, cognitive load, decision lineages, and contradiction audits (actions: summary, velocity, burndown, value_metrics, cognitive_load, critical_path, context_snapshot, active_context, decision_trail, find_related_decisions, contradictions). Use get_analytics instead of query_graph when calculating high-level progress statistics, ROI metrics, or auditing decision conflicts.

Returns summary dashboard, velocity charts, burndown series, cognitive load metrics, critical path DAG, or contradiction reports.

Inspect the append-only event audit ledger, query structured changesets, and generate session post-mortems (actions: log, changelog, post_mortem). Use get_events instead of manage_snapshots when examining the granular chronological sequence of mutations rather than restoring state checkpoints.

Returns chronological event array, structured changeset diff, or session post-mortem markdown report.

Run graph sanity checks, health diagnostics, reference validation, audit chain verification, and storage maintenance (actions: validate, doctor, check_refs, audit_chain, compact, archive, prune_events, version, dedupe). Use run_diagnostics instead of get_analytics when performing database repair, AST reference auto-healing, or verifying SHA-256 event hash chains.

Returns validation diagnostics, health report, broken reference repair log, Merkle chain audit, or maintenance stats.

Multi-agent shared blackboard for asynchronous coordination and mutex leases (actions: get, set, delete, lease, list, post, read). Use use_blackboard instead of manage_nodes when exchanging transient inter-agent messages or mutex resource leases rather than recording persistent graph knowledge.

Returns blackboard message payload, lease acquisition status, active topic list, or deletion confirmation.
