 ## Issue Label Workflow
 
-We use issues, follow this label state machine:
+Automation is handled by [agentloop](https://github.com/guettli/agentloop) running every 5 minutes via cron. Add a label to trigger an agent:
 
-- **State/ToPlan** — Issue needs a plan written by an agent before implementation
+| Label | Trigger | Outcome |
-- **State/Planned** — Plan has been posted as a comment; awaiting human review
+|---|---|---|
-- **State/Ready** — Issue is approved and ready for implementation
+| `loop/plan` | Planning agent reads the issue and writes an implementation plan as a comment | Issue moves to `loop/plan-done` |
-- **State/InProgress** — Set while an agent (or human) is actively working
+| `loop/code` | Coding agent implements the change, creates a branch + PR | Issue moves to `loop/code-done` |
-- **State/Question** — Agent hit a blocker or needs clarification
 
-Full lifecycle:
+**State machine:**
 
 ```
-State/ToPlan → State/Planned   (automated: agent_loop.py runs a planning agent)
+loop/plan  →  loop/plan-in-progress  →  loop/plan-done
-State/Planned → State/Ready    (manual: human reviews the plan and approves)
+                                      ↘  NeedSupervisor  (on failure)
-State/Ready → State/InProgress (automated: agent_loop.py before starting implementation)
+
-State/InProgress → closed      (automated: after PR is merged and CI passes)
+loop/code  →  loop/code-in-progress  →  loop/code-done
-any state → State/Question     (automated or manual: when blocked)
+                                      ↘  NeedSupervisor  (on failure)
 ```
 
-List open issues ready to pick up:
+**Rules:**
+
+- Only issues authored by allowed users are picked up (guettli, guettlibot, guettlibot2, forgejo-actions).
+- An issue with `NeedSupervisor` needs human attention — investigate, fix, then re-label.
+- The coding agent opens a PR but does NOT close the issue. A human reviews the PR and closes the issue after merging.
+- Planning agents only post a comment — they do NOT write code or open PRs.
+- `loop/*` labels are managed by agentloop — do not set them manually while an agent is active.
+
+**Typical lifecycle for a new feature:**
 
-```bash
-fgj issue list --json --state open | jq '[.[] | select(.labels[].name == "State/Ready")] | .[] | {number, title, html_url}'
 ```
-
+1. Create issue
-Rules:
+2. Add label loop/plan   → agent writes plan as comment
-
+3. Review plan, request changes or approve
-- Never start implementation on an issue without `State/Ready`
+4. Add label loop/code   → agent implements + opens PR
-- Planning agents only post a plan comment — they do NOT write code or open PRs
+5. Review PR, merge
-- After `State/Planned`, a human must review the plan and manually add `State/Ready`
+6. Close issue
-- When working via the agent loop: label transitions are set automatically
+```
-  by `agent_loop.py` — do **not** set them yourself.
-- When working manually: switch to `State/InProgress` as your **first action**:
-  ```bash
-  fgj issue edit <NUMBER> --remove-label "State/Ready" --add-label "State/InProgress"
-  ```
-- If blocked, replace current state label with `State/Question` and leave a comment explaining the blocker
-- When done and CI is green, close the issue:
-  ```bash
-  fgj issue close <NUMBER>
-  ```
