+This repo vendors dataquest's private AI knowledge base as the `.dspace-skills/` git submodule. **If
+`.dspace-skills/` is present**, treat **`.dspace-skills/AGENTS.md`** as the authoritative agent guide for this repo:
+read it first, then load the matching profile (`.dspace-skills/profiles/frontend.md` for dspace-angular,
+`.dspace-skills/profiles/backend.md` for DSpace) and pull skills from `.dspace-skills/skills/` on demand. Start any
+PR/backport/test task from `.dspace-skills/SKILLS.md`.
+
+If `.dspace-skills/` is empty (you don't have access, e.g. an outside contributor), ignore this section
+and proceed with the public project conventions.
+
+To enable: `git submodule update --init .dspace-skills` (requires access to
