Large-Scale Refactoring

Perform codebase-wide refactors using AST-aware tools for accuracy and safety. This skill emphasizes scripted approaches over individual file edits and integrates with the gameplan workflow for complex changes.

When to Use

• Renaming symbols (functions, types, variables) across multiple files
• Pattern replacements (e.g., updating API calls, changing import paths)
• Function signature changes that affect many call sites
• Migrating from one API/pattern to another
• Removing deprecated code paths
• Consistent style/naming transformations

Complexity Assessment
