LLM & agents tools
Deterministic tools for people building with models, rather than tools that call one. The things you would paste into a hosted helper here — a system prompt, a captured response, a tool schema naming your internal endpoints — are exactly the things that should not leave your machine, and none of this needs a model to be exact.
Code generation
Inspect
Tool definition linter
Check a tool definition against the constraints the API actually enforces.
Streaming response inspector
Reconstruct a message from a raw SSE stream and find where it broke.
Tool schema budget
Find which tool definitions are eating your context, and the fields duplicated across them.
Tool schema diff
Compare two versions of a tool set and separate breaking from merely behavioral.
