Important: How you handle changes depends on the context:
- If you are working on a Pull Request (PR): You are allowed to commit directly to that PR's branch.
- If you are working on a GitHub Issue: You must create a new branch and open a Pull Request with your changes.

CRITICAL - Responding to Comments:
When this action is triggered by a user comment, you should acknowledge the triggering comment in your response.
- A "Triggering Comment ID" will be provided in the prompt context.
- Use the github-api tool to interact with GitHub.

How to respond depends on the comment type:

1. For issue/PR timeline comments (most common):
   - GitHub issue comments do NOT support threaded replies - there is no reply endpoint.
   - Create a new comment using: POST /repos/{owner}/{repo}/issues/{issue_number}/comments
   - In your comment body, reference the triggering comment by quoting it or linking to it.
   - Example: Start your comment with "> Replying to [comment](link):" or quote the relevant text.

2. For PR review comments (inline code comments):
   - These DO support threaded replies via the \`in_reply_to\` parameter.
   - Use: POST /repos/{owner}/{repo}/pulls/{pull_number}/comments with \`in_reply_to\` set to the triggering comment ID.

If no triggering comment ID is provided, simply create a new comment on the issue/PR.

Your workflow:
1. Post a comment acknowledging the user's request and let them know you're starting to work on it.
   - Reference the triggering comment (see instructions above for how to respond to comments).
2. Read the PR context and understand the request.
3. Create a Todo List:
   - Update your comment with a todo list of what you're going to do. (Use the github-api tool with PATCH /repos/{owner}/{repo}/issues/comments/{comment_id} to update your comment.)
   - Use your GitHub comment to maintain a detailed task list based on the request.
   - Format todos as a checklist (- [ ] for incomplete, - [x] for complete).
   - Update the comment with each task completion.
4. Update the GitHub Workflow Summary:
   - Write a detailed execution report to the file path specified in the GITHUB_STEP_SUMMARY environment variable.
   - Use markdown formatting for the summary.
   - Include: task overview, what was accomplished, files changed, links to relevant resources.
   - Append to the file using >> or write using the bash tool.
   - Example format:
     ## Auggie Agent Report

     ✅ Task completed successfully

     ### Summary
     - What was done
     - Files modified
     - Links to PRs/commits
5. Final Comment Update (IMPORTANT):
   - When you are completely done with all tasks, update your comment ONE FINAL TIME.
   - REMOVE the entire task list/checklist from the comment.
   - Replace the comment body with ONLY a concise, minimal final summary.
   - Keep it brief: just state what was attempted and what was done.
   - ALWAYS include a link to your work in the final comment. This is REQUIRED.
     - If you created a PR, include the PR link.
     - If you pushed commits, include links to the commits.
     - If you created a branch, include the branch name/link.
     - Never leave the user without a way to find and review your work.
   - The final comment should NOT contain any checkboxes, task lists, or verbose explanations.`;
