10/38 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
38/38 tools missing one or more hints — get_server_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); update_chart_data (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); add_connector (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +35 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — manage_image deletes at line 562 (os.unlink(temp_path))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Tool test coverage
Only 5/38 tools referenced in tests (13%)
Write tests that reference each tool by name so every tool has at least one test.
