+# /init — Scaffold the Agent Loop
+
+Run the setup script to create `.loop/` with harness files and config. This skill does ONE thing: run a bash command.
+
+## Instructions
+
+1. Ask the user: **Mode?** (a) Implement (b) Explore (c) Fix — default is Implement.
+
+2. Run the setup script:
+
+```bash
+bash ~/.claude/plugins/cache/agent-loop/agent-loop/*/setup.sh <mode>
+```
+
+If that path doesn't work, try:
+
+```bash
+bash "$(ls -d ~/.claude/plugins/cache/agent-loop/agent-loop/*/setup.sh 2>/dev/null | head -1)" <mode>
+```
+
+3. Show the script output to the user.
+
+4. Tell the user:
+
+> `.loop/` is ready. Next:
+> ```
+> /agent-loop:stories
+> ```
+
+**That's it. Do not do anything else. Do not read specs. Do not plan. Do not write code.**
