The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
OT_CWDDO_NOT_TRACKOneTool sends anonymous startup pings (event type, version, OS). No personal data. Opt out: export =1 or set telemetry.enabled: false in onetool.yaml. [Details](docs/telemetry.md)OT_LOG_VERBOSEOT_LOG_LEVELOT_LOG_DIROT_COMPACT_MAX_LENGTHTool annotations
1/3 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
2/3 tools missing one or more hints — brave_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); brave_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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
2/3 tools referenced in tests (67%)
Write tests that reference each tool by name so every tool has at least one test.
Readable source code
1 file are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
