Tool Schema Linter

Lint the function-calling tool definitions your agent exposes, so it picks the right tool instead of the wrong one or none.

What it flags

How to run

Point it at your tool-definition JSON or pipe it in. Read-only.

Good to know

This is heuristic; the unsafe-tool rule is advisory. It is distinct from REST API tooling: this targets function-calling definitions.

Questions

Who is this for?

Anyone building agents, MCP servers, or function-calling apps.

Does it change anything?

No. Read-only. It flags issues for you to fix.
