Branch Review

Inspect the changes made in this Git branch. Identify any possible issues and suggest improvements. Do not write code. Explain the problems clearly and propose a brief plan for addressing them.

Usage

/review-branch [issue]

• issue (optional): GitHub issue number or URL for additional context

Examples

/review-branch
/review-branch 123
/review-branch https://github.com/videojs/v10/issues/123

Source Issue (optional)

$ARGUMENTS

If an issue number or URL was provided above, fetch the issue details using GitHub tools to get additional context.

Your Tasks

You are an experienced software developer with expertise in code review.

Step 1: Gather Change Context

1. Run git diff --name-only $(git merge-base HEAD main)...HEAD to list changed files
2. Run git diff $(git merge-base HEAD main)...HEAD to see the full diff
3. If an issue was provided, fetch its details for context

Step 2: Categorize Changes

Categorize the changed files to determine which review criteria apply:

File Pattern	Category	Skills
packages/*/src/**/*.ts (non-test)	API/Code	api
packages/html/**, packages/react/** (UI)	UI Components	component, aria
site/**/*.md, **/README.md, **/CLAUDE.md	Documentation	docs
site/**/reference/*.mdx	API Reference	api-reference
packages/*/src/**/*.test.ts	Tests	General review
.claude/**	Agent Config	General review
Config files (.json, .config.*)	Configuration	General review

Report detected categories before proceeding:

Detected changes: [API/Code], [Documentation], [UI Components], etc.

Step 3: Load Skills (Optional)

For deeper domain-specific review, load the relevant skill:

Category	Load Skill	For Deeper Review
API/Code	api	api/review/workflow.md
UI Components	component	component/review/workflow.md
UI Components	aria	aria/review/workflow.md
Documentation	docs	docs/review/workflow.md

Skip this step for quick reviews using the inline checklists below.

Step 4: Apply Skill-Based Review

Based on detected categories, load the relevant skill's review checklist:

Category	Load Checklist
API/Code	api/review/checklist.md
UI Components	component/review/checklist.md
Accessibility	aria/review/checklist.md
Documentation	docs/review/workflow.md

For test changes, apply these checks:

• Tests follow act → assert pattern
• Test file named <module>.test.ts
• describe() uses exact exported name
• Uses vi.fn() for mocks
• Tests live in tests/ directory next to implementation

Step 5: General Code Review

In addition to skill-based checks, review for:

• Code quality and readability — matches codebase style
• Potential bugs or logical errors
• Edge cases that may not be handled
• Performance considerations — 60fps for UI, no unnecessary re-renders
• Security vulnerabilities
• Backwards compatibility (if applicable)
• Test coverage — are changes adequately tested?

Step 6: Produce Summary

Structure your review as:

## Change Summary

[1-2 sentences describing what changed]

## Detected Categories

- [x] API/Code changes
- [ ] UI Component changes
- [x] Documentation changes
- [ ] Test changes

## Findings

### [SEVERITY] Issue title

**What:** Brief description
**Where:** `path/to/file.ts:42`
**Why:** Impact on users/developers
**Fix:** Concrete suggestion

### [SEVERITY] Another issue...

## Recommendations

[Prioritized list of suggested improvements]

Severity Levels:

Level	Meaning	Action
CRITICAL	Breaks functionality, type safety, or a11y	Must fix before merge
MAJOR	Violates core principles, hurts DX	Should fix
MINOR	Suboptimal but workable	Consider fixing
NIT	Polish, style preferences	Optional

Think deeply about the implications of the changes here and proposed.

ONLY CREATE A SUMMARY. DO NOT WRITE ANY CODE.
