Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

All four hints declared on every tool
34/41 tools missing one or more hints — onyx_admin_list_connectors (missing: destructiveHint); onyx_admin_connector_status (missing: destructiveHint); onyx_admin_list_credentials (missing: destructiveHint), +31 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.
openWorldHint matches behaviour
21 tools claim openWorldHint=false but make outbound HTTP — onyx_admin_ingest_document → /onyx-api/ingestion (line 91); onyx_admin_run_connector → /manage/admin/connector/run-once (line 109); onyx_admin_delete_ingested_document → dynamic (line 125)
Either flip openWorldHint to true (acknowledging external reach) or refactor the handler to avoid outbound HTTP. If the only network calls are to a known fixed endpoint that you consider part of the tool itself, document that and keep openWorldHint=false; otherwise true is honest.
Tool inputs are validated
40/41 tool handlers declare input schemas (98%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 7/41 tools referenced in tests (17%)
Write tests that reference each tool by name so every tool has at least one test.
