19 runtime dependencies (24 dev), 1 flagged: playwright-core
Tool annotations
154/339 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
339/339 tools missing one or more hints — search (missing: destructiveHint, idempotentHint, openWorldHint); fetch (missing: destructiveHint, idempotentHint, openWorldHint); ebay_get_oauth_url (missing: destructiveHint, idempotentHint, openWorldHint), +336 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
158/339 tools referenced in tests (47%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 call in production code run through a shell (src/utils/security-checker.ts:199)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — axios@1.16.0 (high), sharp@0.34.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
2/19 production deps stale: prompts@2023-10-21 (2.9y), dotenv-stringify@2024-05-23 (2.3y)
