| 17 | |
| 18 | Focus your review on: |
| 19 | |
| 20 | **Code Correctness** |

| 22 | - Edge cases not handled |
| 23 | - Proper error handling |
| 24 | |
| 25 | **Project Conventions** |

| 49 | - Focus ONLY on actionable suggestions and improvements |
| 50 | - DO NOT summarize what the PR does |
| 51 | - DO NOT provide general commentary |
| 52 | - Highlight specific issues with line references |
| 53 | - Suggest concrete improvements |
| 54 | |
| 55 | **Post Comments Using GitHub API:** |
| 56 | ```bash |
| 57 | # Get commit ID |
| 58 | gh api repos/OWNER/REPO/pulls/PR_NUMBER --jq '.head.sha' |
| 59 | |
| 60 | # Post review comment |
| 61 | gh api repos/OWNER/REPO/pulls/PR_NUMBER/comments \ |
| 62 | --method POST \ |
| 63 | --field body="[specific-suggestion]" \ |
| 64 | --field commit_id="[commitID]" \ |
| 65 | --field path="path/to/file" \ |
| 66 | --field line=lineNumber \ |
| 67 | --field side="RIGHT" |
| 68 | ``` |
| 69 | |
| 70 | ## Review Guidelines |
| 71 | |
| 72 | - **Be constructive**: Focus on improvements, not criticism |
| 73 | - **Be specific**: Reference exact lines and suggest alternatives |
| 74 | - **Prioritize issues**: Distinguish between critical issues and nice-to-haves |
| 75 | - **Consider context**: Understand project requirements and constraints |
| 76 | - **Check for patterns**: Look for repeated issues across files |
| 77 | |
| 78 | ## Output Format |
