| ${CLAUDE_ISSUE_BODY} | |
| Instructions: | |
| 1. Understand the root cause of the issue deeply before making any changes. | |
| 2. Make the minimal change that fixes the issue — no unrelated refactoring. | |
| 3. Follow the existing code style, naming conventions, and formatting. | |
| 4. If the project has a test suite, add or update a test that covers this fix. | |
| 5. Run the test suite and make sure all tests pass. | |
| 6. Stage all changed files with 'git add'. | |
| 7. Commit with the message: fix: <short description> (fixes #${CLAUDE_ISSUE_NUMBER}) | |
| 8. Do NOT push — only commit locally. | |
| 9. If you cannot confidently fix this issue without breaking anything, output exactly: | |
| CANNOT_FIX: <reason> | |
| and make no changes." | |
