All four hints declared on every tool

31/31 tools missing one or more hints — bazel (missing: destructiveHint, idempotentHint, openWorldHint); build (missing: destructiveHint, idempotentHint, openWorldHint); esbuild (missing: destructiveHint, idempotentHint, openWorldHint), +28 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.

Destructive tools are labelled

1 tool perform destructive updates without destructiveHint — esbuild deletes at line 243 (unlink(metafilePath))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Tool inputs are validated

30/31 tool handlers declare input schemas (97%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

Only 10/31 tool handlers wrap calls in try/catch (32%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool test coverage

14/31 tools referenced in tests (45%)

Write tests that reference each tool by name so every tool has at least one test.

Shell command execution

11 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
