Pr Ready

Prepare the code for a pull request by performing a comprehensive cleanup and quality check.

Scope

If $ARGUMENTS is provided, focus on that file or directory. Otherwise, use git diff --name-only $(git merge-base HEAD main)...HEAD to get the list of changed files on the current branch.

Step 1: Identify Files to Review

1. If a specific path was provided, use that
2. Otherwise, get all changed files on the current branch compared to main
3. Filter to only include source files (.ts, .tsx, .js, .jsx)

Step 2: Debug Statement Check

Search for and report any debug statements that should be removed:

• console.log statements (except those in legitimate logging utilities)
• console.debug, console.info, console.warn, console.error (evaluate if intentional)
• debugger statements
• Commented-out console.* statements
• TODO or FIXME comments that should be addressed before PR

For each finding, report:

• File path and line number
• The offending code
• Recommendation (remove, keep, or convert to proper logging)

Step 3: DRY (Don't Repeat Yourself) Analysis

Look for code duplication:

1. Repeated logic patterns: Similar code blocks appearing in multiple places
2. Copy-pasted functions: Functions with minor variations that could be parameterized
3. Repeated JSX structures: Similar UI patterns that could be extracted into components
4. Duplicate type definitions: Types or interfaces defined multiple times
5. Repeated utility code: String manipulation, date formatting, etc. that could be centralized

For each duplication found:

• List all locations where the pattern appears
• Suggest a refactoring approach (extract to utility, create shared component, etc.)
• Estimate the code reduction

Step 4: React Component Structure Review

For each React component, check:

Component Size

• Components should be under 150 lines
• If larger, identify logical boundaries for splitting

Single Responsibility

• Each component should have one clear purpose
• Flag components that do too many things

Component Splitting Opportunities

• Large render methods that could be broken into smaller components
• Repeated JSX patterns within a component
• Complex conditional rendering that could be extracted

Hooks Organization

• Business logic should be in custom hooks, not inline
• Related state should be grouped into custom hooks
• Effects should be organized and commented if complex

Step 5: Prop Drilling Detection

Identify prop drilling issues where props are passed through multiple component layers:

1. Direct prop drilling: Props passed through 3+ component levels without being used
2. Context candidates: Data that's needed by many components and should use React Context
3. State lifting issues: State that's lifted too high and causes unnecessary re-renders

For each prop drilling issue:

• Show the prop's journey through components
• Recommend a solution:
  • Use React Context
  • Use composition (children pattern)
  • Co-locate state closer to where it's used
  • Use a state management solution

Step 6: Additional Quality Checks

• Unused imports: Imports that aren't being used
• Unused variables: Variables declared but never referenced
• Dead code: Functions or components that are never called
• Commented-out code: Old code that should be deleted, not commented
• Inconsistent naming: Variables or functions that don't follow project conventions
• Missing TypeScript types: Any any types or missing type annotations

Step 7: Offer to Fix

After presenting the report, ask the user if they want you to:

1. Fix all critical issues automatically
2. Fix specific issues (let them choose)
3. Just report without making changes

If they want fixes applied:

• Remove debug statements
• Remove unused imports and dead code
• Extract duplicated code into utilities or components
• Split large components
• Add React Context where prop drilling is detected
