+# OpenHands Agent
+
+OpenHands prefers a root-level `AGENTS.md` as always-on context injected at
+conversation start — this kit's `AGENTS.md` needs no changes or pointer file.
+
+- **V0**: repo-specific instructions can additionally live in
+  `.openhands/microagents/repo.md`.
+- **V1**: prefer `.openhands/skills/` for repo-specific skills; `.openhands/microagents/`
+  is still read for backward compatibility.
+- If you want the `SKILLS.md` roles loaded as on-demand context (rather than always
+  injected), convert each role into a microagent/skill file under
+  `.openhands/skills/<role>/` with the appropriate frontmatter trigger.
