    Run a traced concurrency conflict plus failure-storm scenario.

  • demo_explain_idempotency_conflict

    Run a traced idempotency-conflict flow through WriteCore.

  • demo_explain_run

    Run a traced demo flow, then explain the run immediately.

  • demo_explain_run_failure

    Run a traced failing flow, then explain the failed run immediately.

  • demo_explain_semantic_failure

    Run a traced semantic-corruption flow and explain the failed validation.

  • explain_customer

  • init_engine

    Initialize persistent engine storage.

  • insert_row

    Insert one row into the persistent engine.

Show 32 more tools
  • memory_search

    Search memory entries by semantic similarity and metadata filters.

  • memory_upsert

    Upsert one operational memory entry for semantic recall.

  • project_append_event

    Append a generic project event to the local event log.

  • project_capabilities

    Return declared runtime capabilities and contract coverage.

  • project_capture_baseline

    Capture a baseline snapshot and return a unified verdict envelope.

  • project_compare_baseline

    Compare current benchmark/scenario results against a stored baseline.

  • project_delete_entity

    Delete a declared entity from the generic state store.

  • project_explain_run

    Read one run explanation through the generic project explain entrypoint.

  • project_export_state

    Export generic project state as a JSON snapshot.

  • project_get_defaults

    Return default workspace, paths, runtime mode, and project metadata.

  • project_get_entity

    Load one declared project entity by identity key.

  • project_ingest_trace

    Append one normalized trace record through the generic project ingest path.

  • project_list_entities

    List declared project entities from the generic state store.

  • project_list_heuristics

    List declared heuristic profiles available for generic project analysis.

  • project_manifest

    Describe project state roots, schemas, and supported regression primitives.

  • project_run_heuristic

    Run one declared heuristic profile over a source and persist the analysis through project state.

  • project_run_regression

    Run the explain-first regression bundle and return a unified verdict.

  • project_tool_catalog

    Return the full MCP tool catalog with groups, entrypoints, and summaries.

  • project_upsert_entity

    Create or update a declared entity in the generic state store.

  • record_tool_trace

  • report_drift_bug

    Increment and persist split-logic drift bug counter.

  • run_e2e_flow

    Execute full MiniPG + MiniDatabricks + DuckDB end-to-end flow.

  • scenario_load_test

  • schema_evaluate_full_tool

    One-shot: load schema → run EXPLAIN (from query_profiles_json/seed_sql_json) → evaluate. Generic: you supply queries and optional seed SQL.

  • schema_evaluate_tool

    Build verdict from schema metadata and EXPLAIN outputs; write evaluation_report.json and verdict.md. If query_profile_names empty, discovers explain_*.txt in artifacts.

  • schema_explain_tool

    Run EXPLAIN for each profile in query_profiles_json (JSON: name -> SQL). Optional seed_sql_json (JSON array of SQL) runs before EXPLAIN. Writes explain_<name>.txt.

  • schema_load_tool

    Ingest DDL from file or raw text, validate with DuckDB, store metadata in project state (schemas/).

  • similar_incidents

    Find semantically similar historical incidents.

  • upsert_row

    Upsert one row by order_id.
