## Read with an AI or as Markdown

Use [llms.txt](/llms.txt) to discover the English articles and their descriptions; [llms-full.txt](/llms-full.txt) combines the English titles, descriptions, and full bodies. These endpoints are not Japanese translations. For Japanese or an individual English article, append `.md` to its localized URL, such as [this English guide in Markdown](/en/docs/index.md) or [the Japanese guide in Markdown](/ja/docs/index.md). Requesting an article with `Accept: text/markdown` also returns Markdown; ordinary browser links above open HTML.

The [outside-agent operating contract](/orchestration-skill.md) explains how an external coding agent operates aachat from a connected repository. The [support contract](/aachat-support.md) is the diagnostic procedure loaded by `aachat support`. Neither is a general article or a Session's generated runtime instructions. Use [Connected Repo](/en/docs/connected-repo) for connection steps and [Troubleshooting](/en/docs/troubleshooting) for symptoms, then read only the contract needed for the work.
