VETKA MCP exhibits significant definition quality gaps. While 16 tools are registered with descriptions and input schemas, most descriptions are generic or lack actionable guidance. Parameter descriptions are sparse or missing entirely. No output schemas are documented. Error handling is absent, tools provide no recovery guidance. Tool naming is inconsistent (vetka_* prefix on some, bare verbs on others). Critical security tools like execute_code lack proper constraints and confirmation patterns. The semantic_search, knowledge_graph, and arc_gap tools reference external systems (Qdrant, knowledge bases) without documenting expected response structures or failure modes. Artifact management tools (approve/reject/edit) lack idempotency markers and confirmation workflows. Overall, definitions read as API pass-throughs rather than LLM-optimized tool interfaces.

• Document output schemas for all 16 tools. For semantic_search, specify: {results: [{file: string, score: float, content: string}], total: int}. For health_check: {status: 'healthy'|'degraded'|'unhealthy', uptime_seconds: int, memory_mb: int, components: {name: string, status: string}[]}.
• Add enum constraints to parameters with fixed valid values. Convert 'metric_type' description to schema enum: ['code', 'performance', 'system']. Add bounds to numeric params: depth (1-10), limit (1-50), timeout (1-300).
• Wrap execute_code in a confirmation pattern: add a 'dry_run' boolean parameter (default true) that returns the command that would execute without running it. Require explicit dry_run=false for actual execution. Document sandbox limitations and command injection risks.
• Add error recovery guidance to descriptions. E.g., read_file: 'Returns file content or error. If file not found, try search_files() to locate it.' knowledge_graph: 'If query returns no results, try semantic_search() for broader discovery.'
• Mark artifact tools with idempotency hints. Document: 'Calling approve_artifact twice with the same artifact_id is safe, the second call returns success without re-processing.' Add artifact_id validation: 'Must match pattern art_TIMESTAMP_HASH or filepath like artifacts/*.py'.
