V18 / TOOL LIBRARY

A useful kind
of power.

Find a function. Read its contract. Inspect its source. These tools are discovered from the selected version, not copied from a future release.

Only tools introduced in V18 are listed. Earlier additions are available under their version tabs.

Tools are code, not claims.

The main agent, opt-in examples, and scenario-only functions have different scopes. A tool listed inside a greeting scenario is not automatically available to every chat. Saved C# scenario tools run as trusted application code with the host's permissions.
