Three tools with basic verb-noun naming (search_patents, get_patent, get_patent_claims). All have descriptions (50-100 chars, below the 194-char baseline). Input schemas visible in testclient but NOT in actual tool definitions, only inferred from test calls. No parameter descriptions in schemas. No output schema documented. No error handling guidance. No tool annotations. Composition is reasonable (three distinct operations), but schema completeness and parameter documentation are severely lacking.

• Provide complete tools/ package source showing actual tool registration with mcp.AddTool(). Include full schema definitions with parameter types and descriptions.
• Add parameter descriptions to all inputs. E.g., 'query: Search term (string, 1-500 chars). Searches patent abstracts, titles, and inventor names.' and 'publication_number: Patent ID in format US-XXXXXXX-B1 or US-XXXXXXX-A1'.
• Document output schema. Define the structure returned by each tool: e.g., search_patents returns [{publication_number, title, abstract, filing_date, grant_date, inventors, assignees}].
• Add error handling with recovery hints. E.g., 'BigQuery timeout: Try reducing limit parameter or refining query. If error persists, check GCP_PROJECT_ID and GOOGLE_APPLICATION_CREDENTIALS.'
• Add tool annotations. Mark all three tools with readOnlyHint=true since they only query data and never modify state.
