# API reference

> Summary: Every public type in the Tracon packages, generated from the compiled assemblies and their XML documentation.

625 public types across the 16 packages that ship a library API of
their own. These pages are generated from the compiled assemblies and the XML
documentation that ships inside each
`.nupkg`. The generator removes compiler-only members and repository history,
then verifies every internal link for a reference that reads cleanly on the web.

Use the sidebar to browse by package, or the search box — the reference is indexed
along with the rest of the site.

`Tracon` and `Tracon.Templates` are absent on purpose: the first is a meta
package that only carries references, and the second ships a `dotnet new` template
rather than an API.

## Where to start

- [`IAgentCatalog`](/api/tracon.iagentcatalog/) — resolving an agent, the entry point to a run
- [`IRunStore`](/api/tracon.irunstore/) — where every run is recorded
- [`ITraconBuilder`](/api/tracon.itraconbuilder/) — the registration chain
- [`AgentDefinition`](/api/tracon.agentdefinition/) — what an agent is, as data
