Use whenever an agent creates, operates inside, or manages an xo-project. Covers scaffolding a new xo-project via the xo-cowork-api; the boot ritual, canonical file map, and closing conventions for a project folder (AGENTS.md is the operating contract); recording and updating todos across a session; and backing up, restoring, syncing, snapshotting, or migrating xo-projects through the GitHub-backed sync API. Trigger this for any mention of xo-projects, .xo/, xo-cowork-api, or AGENTS.md, and for requests to back up / restore / sync / snapshot / migrate project state — even when the user doesn't name the skill explicitly. Four hard constraints — new xo-projects are created only via the xo-cowork-api; the agent never writes to .xo/ (a watcher service owns that directory); backups and restores happen only through the sync API (never via local tar, zip, cp, rsync, or pushing to an external git remote); and when this skill covers a task, the skill is the way to do it — no improvising with shell commands or ad-hoc c
