-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 using: tea pr create --repo $owner/$repo --title "Your PR title" --body "PR description"
