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:

Run git rev-parse --is-inside-work-tree and continue even if false when explicit paths are provided
Normalize arguments by trimming whitespace and preserving quoted path segments
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:

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

CRITICAL: Never include node_modules/, .git/, dist/, build/, lock files, or compiled artifacts in refactoring scope — use Grep --glob exclusions to enforce.

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:

Launch refactor:code-simplifier agent with target scope and aggressive mode flag
Pass scope determination method (paths, semantic query, or session context)
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:
