Tug Refactor

Semantic code refactoring using tug. Use this skill when the user wants to: - Rename a function, class, method, or variable across multiple files - Change symbol names with automatic reference updates - Refactor identifiers while preserving semantic correctness Trigger patterns: "rename X to Y", "change the name of", "refactor the name", "update all references", "change the function/class/variable name" Note: tug currently supports Python only. Rust support is planned but not yet implemented.

Tug Refactoring Skill

This skill provides semantic refactoring capabilities through the tug CLI tool.

When to Use This Skill

Use tug when the user requests symbol renaming or reference updates, especially:

Multi-file renames (function used in many places)
Class or method renames with inheritance implications
Variable renames that must preserve scoping rules
Any rename where manual find/replace would be error-prone

Available Commands

/tug-apply-rename - Full rename workflow with analyze, review, and apply
/tug-emit-rename - Generate unified diff without applying changes
/tug-analyze-rename - Analyze impact only (no changes, no diff)

Workflow

Identify the symbol: Determine file, line, and column of the symbol to rename
Get the new name: Ask user for the desired new name if not provided
Invoke command: Use /tug-apply-rename for the full workflow

Why Tug Over Manual Editing

Scope-aware: Understands language scoping rules (shadowing, imports, etc.)
Verified: Runs syntax verification before applying changes
Deterministic: Same input always produces same output
Safe: Requires explicit approval before applying changes

CLI Quick Reference

# Analyze impact (read-only, JSON output)
tug analyze python rename --at <file:line:col> --to <new_name>

# Emit diff (read-only, unified diff output)
tug emit python rename --at <file:line:col> --to <new_name>

# Apply rename (modifies files)
tug apply python rename --at <file:line:col> --to <new_name>

Example

User: "Rename the process_data function to transform_data"

Response: I'll use tug to rename this function safely across all files. [Invoke /tug-apply-rename]
