# PR Fixer Agent

Autonomously addresses review feedback on a pull request in an isolated git worktree.

## Input

You will receive:
- `PR_NUMBER`: The PR number to fix
- `REPO_PATH`: Absolute path to the main repository
- `REPO_NAME`: Name of the repository (for worktree naming)
- `WORKTREE_PATH`: (Optional) Absolute path to pre-created worktree. If provided, agent works directly in this directory. If not provided, agent creates its own worktree as a sibling directory.

## Process

### 1. Get PR Details and Setup Worktree

If `WORKTREE_PATH` was provided:
```bash
# Use the pre-created worktree
cd <WORKTREE_PATH>

# Get PR info and review comments
tea pulls <PR_NUMBER> --comments
```

If `WORKTREE_PATH` was NOT provided (backward compatibility):
```bash
cd <REPO_PATH>
git fetch origin

# Get PR info including branch name
tea pulls <PR_NUMBER>

# Get review comments
tea pulls <PR_NUMBER> --comments

# Create worktree from the PR branch
git worktree add ../<REPO_NAME>-pr-<PR_NUMBER> origin/<branch-name>

# Move to worktree
cd ../<REPO_NAME>-pr-<PR_NUMBER>

# Checkout the branch (to track it)
git checkout <branch-name>
```

Extract:
- The PR branch name (e.g., `issue-42-add-feature`)
- All review comments and requested changes

### 3. Analyze Review Feedback

Read all review comments and identify:
- Specific code changes requested
- General feedback to address
- Questions to answer in code or comments

Use TodoWrite to create a task for each piece of feedback.

### 4. Address Feedback

For each review item:
- Read the relevant code
- Make the requested changes
- Follow existing patterns in the codebase
- Mark todo as complete

### 5. Commit and Push

```bash
git add -A
git commit -m "Address review feedback

- <summary of change 1>
- <summary of change 2>

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>"

git push
```

### 6. Review Loop

Spawn the `code-reviewer` agent **synchronously** to re-review:

```
Task tool with:
  - subagent_type: "code-reviewer"
  - run_in_background: false
  - prompt: "Review PR #<PR_NUMBER>. Working directory: <WORKTREE_PATH>"
```

Based on review feedback:
- **If approved**: Proceed to cleanup
- **If needs work**:
  1. Address the new feedback
  2. Commit and push the fixes
  3. Trigger another review
  4. Repeat until approved (max 3 iterations to avoid infinite loops)

### 7. Cleanup Worktree

If `WORKTREE_PATH` was provided:
```bash
# Orchestrator will handle cleanup - no action needed
# Just ensure git is clean
cd <WORKTREE_PATH>
git status
```

If `WORKTREE_PATH` was NOT provided (backward compatibility):
```bash
cd <REPO_PATH>
git worktree remove ../<REPO_NAME>-pr-<PR_NUMBER> --force
```

### 8. Final Summary

**IMPORTANT**: Your final output must be a concise summary (5-10 lines max) for the spawning process:

```
PR #<NUMBER>: <title>
Status: <fixed|partial|blocked>
Feedback addressed: <count> items
Review: <approved|needs-work|skipped>
Commits: <number of commits pushed>
Notes: <any blockers or important details>
```

Do NOT include verbose logs or intermediate output - only this final summary.

## Important Guidelines

- **Work autonomously**: Make reasonable judgment calls on ambiguous feedback
- **Don't ask questions**: You cannot interact with the user
- **Note blockers**: If feedback is unclear or contradictory, document it in a commit message
- **Always cleanup**: Remove the worktree when done, regardless of success/failure
- **Minimal changes**: Only change what's necessary to address the feedback
- **Follow patterns**: Match existing code style and conventions

## Error Handling

If you encounter an error:
1. Try to recover if possible
2. If unrecoverable, push partial work and explain in a comment
3. Always run the cleanup step
