frontend-code-review: A Skill That Automates Frontend Code Review for Dify
Introduction
Frontend code review is often a significant burden for development teams. There are numerous areas to check, including code quality, performance, and business logic accuracy, and much depends on the reviewer's experience and attention to detail.
frontend-code-review is provided as an official skill for Dify (an open-source LLM app development platform with 127K+ Stars). It enables Claude Code to perform structured, checklist-based frontend code reviews.
What This Skill Does
frontend-code-review provides two review modes and structured output formats.
Review Modes
- pending-change review - Performs a batch review of uncommitted and unpushed changes in Git
- File-targeted review - Runs a review on specific files or directories
Checklist Categories
- Code Quality - Naming conventions, type safety, code structure appropriateness
- Performance - Unnecessary re-renders, memoization opportunities, bundle size impact
- Business Logic - Specification alignment, edge case handling, error handling
Output Formats
- Template A (findings) - Lists issues with Urgency levels (High/Medium/Low)
- Template B (no issues) - A concise approval report when no problems are found
Installation
Place it in the .claude/skills/ directory of the Dify project:
mkdir -p .claude/skills/frontend-code-review
If you've cloned the Dify repository, the skill may already be included in the .claude/skills/ directory.
Usage
Pending-Change Review
Use this when you want to review all working changes at once:
"Review the frontend changes"
Claude Code analyzes the Git diff and generates a review report based on the checklist. Urgency metadata makes high-priority issues immediately visible.
File-Targeted Review
Use this when you want to focus the review on specific components or modules:
"Run a code review on the web/app/components/workflow/ directory"
A focused review is performed on code within the specified files or directories.
Using Review Results
Issues found during review are prioritized by Urgency level:
- High - Requires immediate fix (bugs, security issues)
- Medium - Should be addressed soon (performance, maintainability)
- Low - Recommended improvements (code style, best practices)
Important Notes
- The skill is specialized for TypeScript/React/JS files. Backend code (Python, etc.) is not covered
- Checklist items are based on Dify project conventions and directory structure
- Automated review is a supplementary tool. Final decisions should be made by human reviewers
- Reviews may take longer when there are extensive file changes
Summary
frontend-code-review automates Dify project frontend code reviews with a checklist-based approach. Two review modes and Urgency-based prioritization improve both review efficiency and quality. It's especially effective for maintaining review consistency in team development.
