Facts about each app for the model (release notes, requirements such as database versions, STOP cases, checks, the way back): table skills (migration v4), config/skills/<project>.md imported once from the old system (frontmatter dropped, no secrets), added to the database at driver start when missing and never overwritten, GET/POST /api/projects/:project/skill and a Skill panel on the app page. Only the skill of the project the model works on will be loaded. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
