Code Reviewer

This skill guides the agent in conducting professional and thorough code reviews for both local development and remote Pull Requests.

Workflow

1. Determine Review Target

• Remote PR: If the user provides a PR number or URL (e.g., "Review PR #123"), target that remote PR.

• Local Changes: If no specific PR is mentioned, or if the user asks to "review my changes", target the current local file system states (staged and unstaged changes).

2. Preparation

For Remote PRs:

• Checkout: Use the GitHub CLI to checkout the PR. gh pr checkout <PR_NUMBER>

• Preflight: Execute the project's standard verification suite to catch automated failures early. npm run preflight

• Context: Read the PR description and any existing comments to understand the goal and history.

For Local Changes:

• Identify Changes:

• Check status: git status

• Read diffs: git diff (working tree) and/or git diff --staged (staged).

• Preflight (Optional): If the changes are substantial, ask the user if they want to run npm run preflight before reviewing.

3. In-Depth Analysis

Analyze the code changes based on the following pillars:

• Correctness: Does the code achieve its stated purpose without bugs or logical errors?

• Maintainability: Is the code clean, well-structured, and easy to understand and modify in the future? Consider factors like code clarity, modularity, and adherence to established design patterns.

• Readability: Is the code well-commented (where necessary) and consistently formatted according to our project's coding style guidelines?

• Efficiency: Are there any obvious performance bottlenecks or resource inefficiencies introduced by the changes?

• Security: Are there any potential security vulnerabilities or insecure coding practices?

• Edge Cases and Error Handling: Does the code appropriately handle edge cases and potential errors?

• Testability: Is the new or modified code adequately covered by tests (even if preflight checks pass)? Suggest additional test cases that would improve coverage or robustness.

4. Provide Feedback

Structure

• Summary: A high-level overview of the review.

• Findings:

• Critical: Bugs, security issues, or breaking changes.

• Improvements: Suggestions for better code quality or performance.

• Nitpicks: Formatting or minor style issues (optional).

• Conclusion: Clear recommendation (Approved / Request Changes).

Tone

• Be constructive, professional, and friendly.

• Explain why a change is requested.

• For approvals, acknowledge the specific value of the contribution.

5. Cleanup (Remote PRs only)

• After the review, ask the user if they want to switch back to the default branch (e.g., main or master ).
