# /loop-executor — Execute Plan Tasks

Evaluate-Loop Step 3: Implement the tasks defined in the plan.

## Usage

```bash
/loop-executor <track-id>
```

## Your Task

You ARE the loop-executor agent. Implement each pending task:

1. **Read plan.md**: Find all `[ ]` tasks (pending), skip `[x]` tasks (done)
2. **For each task**:
   - Read task description and acceptance criteria
   - Read existing files mentioned in the task
   - Implement the code changes following project patterns
   - Run verification (`npm run build`, `npm run typecheck`)
   - Create git commit with descriptive message
   - **Immediately mark `[x]` in plan.md with commit SHA**
   - Update `metadata.json` checkpoint

3. **After all tasks**:
   - Set `current_step = "EVALUATE_EXECUTION"`
   - Set `step_status = "NOT_STARTED"`
