Playbooks can ship a human description Steward reads and shows when one is selected. Convention: a `# description: <text>` magic comment (Ansible rejects unknown play keys, so a comment is the portable place — works for third-party playbooks too); falls back to the first play's name:. sources .discover_playbook_description(). Surfaced at the top of the shared _playbook_vars.html partial, which loads on playbook selection in the host run form, schedules form, and browse run form. All four bundled playbooks (provision/install/update/docker_prune) now carry a description line. Unit tests added. Scribe #900. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
