custom_tools

Patch custom tool

Updates mutable custom tool fields. Only supplied fields change; changing code bumps the version. Requires a token with write access.

patch/v1/custom-tools/{id}

Path parameters

idstring required

Custom tool id.

Example:kg77c0dy0mgdpzmqz6tesry8w184002s

Query parameters

workspace_idstring

Optional workspace override. If omitted, Conduit resolves the tool's workspace automatically.

Example:j57demo8f8x7c9v0n2q4r6t8y1u3i5o

Request body

namestring

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.

descriptionstring

language'python' | 'javascript'

Runtime the tool's code is executed in. Determines the entrypoint signature and which dependencies are available (see GET /v1/custom-tools/runtimes).

codestring

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.

parametersobject

Parameters the tool accepts, keyed by parameter name. Each becomes a key in the params object/dict passed to main.
