131/301 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
301/301 tools missing one or more hints — list_ebay_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); enable_ebay_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); disable_ebay_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +298 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
Only 0/3 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/3 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 12/301 tools referenced in tests (4%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dependency freshness
2/17 production deps stale: prompts@2023-10-21 (2.8y), dotenv-stringify@2024-05-23 (2.2y)
