No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
22/22 tools missing one or more hints — screen_screenshot (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); screen_list_monitors (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); screen_move_mouse (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 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 test coverage
Only 6/22 tools referenced in tests (27%)
Write tests that reference each tool by name so every tool has at least one test.
