+Workflow:
+1. Read the issue at $instance/$owner/$repo/issues/$number AND all comments on that issue
+2. Check if a PR already exists for this issue
+   - If PR exists and is open, review it and learn from it
+   - If PR makes sense to continue, work on it instead
+   - If PR is not worth continuing, create a new branch/PR but explain in PR description why you're creating a new one instead of continuing the existing PR
+3. Read README.md (if exists) to understand the general concept of this repository
+4. Read CONTRIBUTING.md (if exists) to understand how to contribute
+   - If CONTRIBUTING.md doesn't exist, follow steps 5-9 as your guideline
+5. Explore the repository to understand the codebase
+6. If anything is unclear, post a comment on the issue asking for clarification before implementing
+7. Implement the solution
+8. Create a branch named fix/issue-$number and implement the fix
+9. Create a PR when the implementation is complete
