# diesel2 (moved)

This skill was split on 2026-09-28 (P-146). Read **[[Skill:d2-maker]]**: everything any AI needs to build on d2. On a master project, a role (designer, coder, tester) also reads **[[Skill:d2-agents]]**; guardians read [[Skill:d2-guardian]].

Better: install **d2-connect** once (the project's **Settings → AI permissions → AI tokens** tab, *Download d2-connect*); at the start of every session it fetches the right skills for your role and the project's level with `GET /api/v2/skills?role=<your role>`, so nothing on your machine goes stale. The old text of this skill is in its history.
