| name | ghostcrab-gap-auditor |
| description | Audit gaps between a natural-language GhostCrab question and evidence available through MCP on a SQLite workspace. Use when a projection is missing, a Type A contract exists without evidence, required facets or graph edges are not verified, a Type B snapshot is absent, an MCP tool fails, or the user asks what to add to make an operational answer reliable. |
GhostCrab Gap Auditor (Personal)
Purpose
Explain why a business question is not fully answerable yet and propose concrete adjustments. Keep declared capability separate from observed evidence.
Use MCP tool output as evidence. Do not open SQLite directly. Do not use legacy Pro operators (PostgreSQL CLI) or direct SQL.

Delivery context (optional)
Resolve {starterkit} via STARTERKIT_PATHS.md — audit and gate 7–9 phases in {starterkit}/personal-mcp/SOP_SEQUENCE.md.
Vocabulary boundary
Gap categories below are answerability_gap findings. They are not artifact_kind values.
| This skill | Not this |
|---|
answerability_gap (audit result) | graph_gap_rule (persisted validation rule) |
missing_snapshot subtype | answer_snapshot (frozen answer artifact) |
no_projection subtype | analysis_plan (working-memory artifact) |
missing_edges subtype | graph_data_gap from ghostcrab_graph_diagnostics |
| Contradictory graph facts | graph_conflict (not answerability_gap) |
For graph invariant violations, use ghostcrab_graph_diagnostics and graph_gap_rules. For ontology coverage, use ghostcrab_coverage.
Gap categories
All categories are subtypes of answerability_gap:
no_projection — no matching analysis_plan scope for the question.projection_contract_only — contract exists but no supporting facts or graph rows surfaced.missing_dimensions — expected business dimensions absent or unclear.missing_facets — required facet filters or agent_facts rows missing; also when enum keys lack <module>.<slot_snake_case> prefix (verify with ghostcrab_facet_inspect).missing_edges — required graph edges absent or not traversed.missing_snapshot — no answer_snapshot via ghostcrab_projection_get.tool_surface_gap — needed MCP tool missing or failed.ambiguous_intent — multiple scopes match; narrow with the user.
Audit workflow
ghostcrab_status — workspace and health.ghostcrab_workspace_use if workspace unclear.ghostcrab_search / ghostcrab_combined_search with the user question.ghostcrab_schema_inspect / ghostcrab_schema_list for expected shapes (include target=facets module schemas).ghostcrab_facet_inspect for expected business enum keys — must match ENUM_BUSINESS_FACETS.md naming.ghostcrab_pack or ghostcrab_projection_get when answer artifacts matter.ghostcrab_graph_search / ghostcrab_traverse when graph evidence is required.- Compare results to the user question.
For import pipeline gaps, point operators to gcp brain structured-import. For ontology source gaps, prefer MCP ghostcrab_ontology_import when an agent owns the workflow, or gcp brain ontology compile for CLI maintenance.
Output format
{
"workspace_id": "",
"question": "",
"gap_status": "",
"matched_projection": null,
"gaps": [],
"adjustments": [],
"mcp_tools_used": [],
"recommended_next_test": ""
}
Each gap entry: category (answerability subtype above), severity (low|medium|high), evidence, impact. Do not emit artifact_kind on gap entries.
Guardrails
- Do not label a projection ready if only the
analysis_plan contract exists and the user asked for live operational facts.
answer_snapshot is optional; state when analysis_plan + graph search is enough.- Prefer
recommended_next_test over vague advice.
- Never conflate gap audit output with answer artifact registry rows.
