Single tool 'dynamic_openapi_tools' has critical definition gaps. Tool name lacks action verb (should be 'call_openapi_endpoint' or similar). Description is generic and does not explain WHEN to use this tool or what it returns. Input schema properties ('pathNames', 'searchParams', 'requestBody', 'headers') lack individual descriptions, LLMs cannot infer parameter meaning from names alone. No output schema documented. No error handling guidance. Tool definition appears inferred from adapter code rather than explicitly registered with full metadata. Violates 6+ core patterns from the rubric.

• Rename tool to 'call_openapi_endpoint' or 'invoke_api_operation' to start with an action verb and clarify intent.
• Expand description to 100-200 chars: explain that this tool invokes endpoints from a pre-loaded OpenAPI spec, when to use it (e.g., 'Use this to call any API operation defined in the service's OpenAPI specification'), and what it returns (HTTP status, response body, headers).
• Add descriptions to each input schema property: 'pathNames: object mapping path parameter names to values (e.g., {"userId": "123"})', 'searchParams: query string parameters as key-value pairs', 'requestBody: JSON object matching the OpenAPI requestBody schema', 'headers: HTTP headers to include in the request'.
• Document output schema: specify that the tool returns {status: number, body: object, headers: object} or similar, so LLMs know what fields to expect.
• Add error handling: document that the tool returns error responses with actionable messages (e.g., 'Invalid path parameter: userId must be numeric') and guide LLM on retry logic.
