# Pipeline Documentation

`com.unity.pipeline` lets a client — CLI, CI, or an agent — drive a running Unity Editor (or a
development Player) over a local HTTP API by executing registered commands. This is the documentation
index; the [README](../README.md) has the full narrative overview, install steps, and CLI walkthrough.

## Guides

| Page | What it covers |
|------|----------------|
| [Creating commands](creating-commands.md) | The command-authoring API: `[CliCommand]`/`[CliArg]`, the handler + response pattern, and the `MainThreadRequired` / `RuntimeOnly` flags. |
| [Creating authoring commands](authoring-commands.md) | Building content-authoring commands: the authoring root sandbox, `ObjectRef` in / `AuthoringResult` out, and undo grouping — with a worked example for a new content type. |
| [Safety & mutations](safety-and-mutations.md) | Conventions shared by state-changing commands: the `confirm`/`dry_run` gate, Undo grouping via `AuthoringUndoScope`, and the path sandbox. |
| [Connectivity](connectivity.md) | How servers bind localhost, the port ranges, the port/descriptor file, and the bearer-token auth workflow. |
| [Runtime connection & setup](runtime-setup.md) | Running the server in a development Player via `RuntimePipelineManager` and the dev-build gating. |
| [Hot reload](hot-reload.md) | The two hot-reload flavors (in-place and override) with examples, plus the Roslyn / in-memory-assembly architecture. |
| [Tests architecture](testing.md) | Writing command tests via `PipelineClient` (over HTTP) and via direct command calls. |
