# Documentation

> How to drive Radial from the terminal, from your agent, and from your own code.

Radial is an issue tracker with a real command line, a remote MCP server and a
REST API. Nothing in the product calls a model on your behalf; the agent is
yours, and these pages are about pointing it at your issues.

## Start here

**[Agent skills](/docs/skills)**: eleven `rd-*` skills that teach Claude Code
and Codex the whole loop: plan a change into a parent and a few children, file
the tree, build it child by child leaving notes on each issue, and open a pull
request that does not auto-close the siblings. Install them in about a minute.

**[Install and update](/docs/skills/install)**: where the files go for each
client, global versus per-repo, and what to do when a skill does not show up in
the picker.

**[Extending a skill](/docs/skills/extending)**: add your team's rules to a
built-in without forking it, so you keep getting updates and we never overwrite
your conventions.

## The rest of the developer surface

The CLI reference, the MCP tool list and the REST API all live on
[developers](/developers) for now. The command you probably want first:

```bash
npm install -g radial.build && radial auth
```

Every page here is also markdown. Add `.md` to any docs URL, or read
[llms.txt](/llms.txt) for the index and [llms-full.txt](/llms-full.txt) for the
whole corpus in one request.
