Unique tool name within the workspace. Lowercase kebab-case (e.g. lookup-order-status), at most 64 characters. This is how the agent references the tool.
The tool's source code. Must define a single entrypoint named main.
Python: def main(**params): — parameters arrive as keyword args. Return a dict containing a string message key, optionally a rawData key with structured data.
JavaScript: async function main(params) { ... } — parameters arrive as a single object. Return an object containing a string message key, optionally a rawData key.
Writes statically validate that the code defines main and includes a return statement; runtime execution validates the returned object.
Standard library modules are always importable. A curated set of third-party packages installs automatically on first import. Query GET /v1/custom-tools/runtimes for the exact signature, return contract, and available dependencies per language.
