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
79/79 tools missing one or more hints — manage_bitable_app (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); manage_bitable_table (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); manage_bitable_field (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +76 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.
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets not logged
5 secret values sent to console.log
Redact or omit secret values from log output.
