refactor

Refactor Command

Execute automated refactoring for $ARGUMENTS using refactor:code-simplifier agent.

Pre-operation Checks

Goal: Ensure scope resolution is deterministic before launching the agent.

Actions:

1. Run git rev-parse --is-inside-work-tree and continue even if false when explicit paths are provided
2. Normalize arguments by trimming whitespace and preserving quoted path segments
3. Treat an empty argument list as "recent changes" mode

Phase 1: Determine Target Scope

Goal: Identify files to refactor based on arguments or session context.

Actions:

1. If arguments provided: verify as file/directory paths using Glob
2. If paths exist: use them directly as refactoring scope
3. If paths don't exist: treat arguments as semantic query, search codebase with Grep
4. If no arguments: run git diff --name-only to find recently modified code files
5. If no recent changes found: inform user and exit without refactoring

See references/scope-determination.md for search strategies and edge cases.

Phase 2: Launch Refactoring Agent

Goal: Execute refactor:code-simplifier agent with aggressive mode enabled.

Actions:

1. Launch refactor:code-simplifier agent with target scope and aggressive mode flag
2. Pass scope determination method (paths, semantic query, or session context)
3. Agent auto-loads refactor:best-practices skill and applies language-specific patterns

See references/agent-configuration.md for detailed Task parameters.

Phase 3: Summary

Goal: Report comprehensive summary of changes.

Actions:

1. Report total files refactored and changes categorized by improvement type
2. List best practices applied and legacy code removed
3. Suggest tests to run and provide rollback command tailored to actual scope (for example: git restore --worktree --staged <files>)

See references/output-requirements.md for detailed summary format.

Requirements

• Execute immediately without user confirmation
• Refactor ALL matching files when semantic search returns multiple results
• Direct users to /refactor-project for project-wide scope
• Preserve behavior and public interfaces unless user explicitly requests a behavior change
