131/209 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
209/209 tools missing one or more hints — whoami (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_account (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_billing_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +206 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 inputs are validated
188/209 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/209 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 44/209 tools referenced in tests (21%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
