Code Refactor

Code Refactor

Systematic code refactoring across files. Auto-switches to execution mode for 10+ files (90% token savings).

Mode Selection

• 1-9 files: Use native tools (Grep + Edit with replace_all)
• 10+ files: Automatically use code-execution skill

Execution example (50 files):

from api.code_transform import rename_identifier
result = rename_identifier('.', 'oldName', 'newName', '**/*.py')
# Returns: {'files_modified': 50, 'total_replacements': 247}
# ~500 tokens vs ~25,000 tokens traditional

When to Use

• "rename [identifier] to [new_name]"
• "replace all [pattern] with [replacement]"
• "refactor to use [new_pattern]"
• "update all calls to [function/API]"
• "convert [old_pattern] to [new_pattern]"

Core Workflow (Native Mode)

1. Find All Occurrences

Grep(pattern="getUserData", output_mode="files_with_matches")     # Find files
Grep(pattern="getUserData", output_mode="content", -n=true, -B=2, -A=2)  # Verify with context

2. Replace All Instances

Edit(
  file_path="src/api.js",
  old_string="getUserData",
  new_string="fetchUserData",
  replace_all=true
)
