Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

40/40 tools missing one or more hints — cortex_pipeline_start (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cortex_pipeline_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cortex_pipeline_pause (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +37 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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — cortex_auto_heal (line 17: require('fs').writeFileSync(fullPath, cp.content, 'utf-8'))

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

36/40 tool handlers declare input schemas (90%)

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

Tool handlers catch errors

Only 11/40 tool handlers wrap calls in try/catch (28%)

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

Tool test coverage

Only 0/40 tools referenced in tests (0%)

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

Tests pass

npm test failed — tests do not pass

Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.

Shell command execution

6 child_process calls — runs shell commands

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

No arbitrary install scripts

Has postinstall/preinstall script — runs arbitrary code on npm install

Remove postinstall/preinstall hooks unless they’re essential.

Production dependencies are patched

0 critical, 3 high severity in production deps — minimatch@9.0.0 (high), minimatch@9.0.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

2 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

Tool description accuracy

cortex_auto_heal: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
