Outputs are written to demo-output/ unless is set.All four hints declared on every tool
11/11 tools missing one or more hints — drawing (missing: destructiveHint, idempotentHint, openWorldHint); entity (missing: destructiveHint, idempotentHint, openWorldHint); layer (missing: destructiveHint, idempotentHint, openWorldHint), +8 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.
Tool handlers catch errors
Only 2/11 tool handlers wrap calls in try/catch (18%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
