Refactor

Refactor code matching $ARGUMENTS across the codebase using parallel Snipper agents for maximum speed.

Process

Phase 1: Discovery

1. Parse the refactor request from $ARGUMENTS

   • Identify: method name, component name, pattern, or code smell
   • Choose search strategy: Grep for code patterns, Glob for file patterns

2. Find all affected files

   • Use Grep/Glob to search the codebase
   • Exclude: node_modules, .git, dist, build
   • If >15 files found, ask user to confirm or narrow scope

Phase 2: Create Instructions

3. Create task folder: .claude/tasks/refactor-{timestamp}/

4. Create ONE instruction file at instructions.md:

# Refactor: {title}

## Objective
{What to refactor - derived from $ARGUMENTS}

## Pattern to Find
{Exact code pattern or structure to locate}

## Transformation
{How to transform - be specific and adaptive}

## Examples
Before:
{current code}

After:
{refactored code}

## Constraints
- Only modify code matching the pattern
- Preserve all existing functionality
- Follow codebase conventions

Phase 3: Execute in Parallel

5. Group files into batches of max 3 files each

6. Launch Snipper agents in parallel - ALL batches in a SINGLE message:

Using instructions in .claude/tasks/refactor-{id}/instructions.md, refactor:
- {file_1}
- {file_2}
- {file_3}

Read instructions first, then apply the refactor to each file.

Phase 4: Verification

7. Validate changes

   • Run pnpm lint (if available)
   • Run pnpm tsc (if TypeScript)

8. Report summary

   • Files modified
   • Errors encountered
   • Next steps if needed

Example

User: /refactor rename getUserData to fetchUserProfile

1. Grep finds 12 files containing "getUserData"
2. Creates .claude/tasks/refactor-1702489200/instructions.md
3. Groups into 4 batches of 3 files
4. Launches 4 Snipper agents in parallel
5. Runs lint, reports: "Refactored 12 files"
