# For AI agents `xa` ships artifacts for coding agents alongside its code. This page lists them, says where each lives in the repository, and points at the machine-readable copies of this documentation. ## Skills Skills are folders holding a `SKILL.md` (the [Agent Skills](https://agentskills.io) format): a description that tells an agent when to use it and a body with the procedure. Install one into your agent with `gh skill` (any host: `--agent claude-code`, `copilot`, `cursor`, `codex`, `gemini`), or use the copy bundled in the wheel. ### `xa-install` Use when the user wants to install, configure, provision, secure, or troubleshoot `xa` — the cross-machine Claude Code session manager. Triggers on "install xa", "set up xa on this server", "configure xa hosts", "start xa serve", "xa from my phone", "make xa accessible from my phone", "secure xa", "xa config", or any request to use xa for the first time. Also use if the user asks why `xa list` is empty, why a remote host isn't showing, why they can't resume a session, or whether their xa deployment is safe. ```bash gh skill install thorwhalen/xa xa-install --agent claude-code ``` Source: [`xa/data/skills/xa-install`](https://github.com/thorwhalen/xa/tree/HEAD/xa/data/skills/xa-install) (bundled with the pip package). ### `xa-dev` Use when developing on or diagnosing the `xa` package (Claude Code session manager). Triggers on work under /root/py/proj/t/xa, edits to xa/xa/*.py, failing tests, or questions about xa's architecture, layering, or extension points. Not for using xa as an end user — that's the shipped xa-install skill. Source: [`.claude/skills/xa-dev`](https://github.com/thorwhalen/xa/tree/HEAD/.claude/skills/xa-dev). The bundled skills are also on disk after `pip install xa`, under the package's `data/skills/` directory; link them into an agent without network access with `skill link-skills `. ## Machine-readable documentation This site publishes the same documentation in forms that fit an agent's context window: - [`llms.txt`](https://thorwhalen.github.io/xa/llms.txt): an index of every page with a one-line description ([llms.txt](https://llmstxt.org) format) - [`xa.md`](https://thorwhalen.github.io/xa/xa.md): the whole documentation as one Markdown file - `.html.md`: a rendered Markdown twin of every page, advertised from each page's `` with `` - [`objects.inv`](https://thorwhalen.github.io/xa/objects.inv): the Sphinx inventory: a symbol-to-URL index (`sphobjinv convert plain objects.inv -`)
