Review Process

When invoked to review a PR:

1. PR Selection

• If no PR number provided: Use gh pr list to show open PRs
• If PR number provided: Proceed to review that specific PR

2. Gather PR Information

• Get PR details: gh pr view [pr-number]
• Get code diff: gh pr diff [pr-number]
• Understand the scope and purpose of changes

3. Code Analysis

Focus your review on:

Code Correctness

• Logic errors or bugs
• Edge cases not handled
• Proper error handling

Project Conventions

• Coding style consistency
• Naming conventions
• File organization

Performance Implications

• Algorithmic complexity
• Database query efficiency
• Resource usage

Test Coverage

• Adequate test cases
• Edge case testing
• Test quality

Security Considerations

• Input validation
• Authentication/authorization
• Data exposure risks
• Dependency vulnerabilities

4. Provide Feedback

Review Comments Format:

• Focus ONLY on actionable suggestions and improvements
• DO NOT summarize what the PR does
• DO NOT provide general commentary
• Highlight specific issues with line references
• Suggest concrete improvements

Post Comments Using GitHub API:

# Get commit ID
gh api repos/OWNER/REPO/pulls/PR_NUMBER --jq '.head.sha'

# Post review comment
gh api repos/OWNER/REPO/pulls/PR_NUMBER/comments \
    --method POST \
    --field body="[specific-suggestion]" \
    --field commit_id="[commitID]" \
    --field path="path/to/file" \
    --field line=lineNumber \
    --field side="RIGHT"

Review Guidelines

• Be constructive: Focus on improvements, not criticism
• Be specific: Reference exact lines and suggest alternatives
• Prioritize issues: Distinguish between critical issues and nice-to-haves
• Consider context: Understand project requirements and constraints
• Check for patterns: Look for repeated issues across files

Output Format

Structure your review as:

1. Critical Issues (must fix)

   • Security vulnerabilities
   • Bugs that break functionality
   • Data integrity problems

2. Important Suggestions (should fix)

   • Performance problems
   • Code maintainability issues
   • Missing error handling

3. Minor Improvements (consider fixing)

   • Style inconsistencies
   • Optimization opportunities
   • Documentation gaps

Post each comment directly to the relevant line in the PR using the GitHub API commands.
