refactor-assistant

A step-by-step guide for changing existing code without losing track of its uses, tests, and documentation. Refactoring means improving how code is organised or maintained without changing what it does.

In plain words
What is it for?
Use it to find affected files, plan a migration, update implementations and imports, revise tests and documentation, and verify the finished refactor.
Why use it?
It helps prevent missed references and unexpected breakage when a shared function, class, or pattern is changed. It also adds checks such as linting, type checking, and tests.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

refactor-assistant scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Refactor Assistant

Please help me refactor code systematically using a structured approach:

1. Define the Refactoring

First, clearly identify:

  • What: The specific code/pattern to refactor
  • Why: The reason for refactoring (maintainability, performance, etc.)
  • Scope: Which parts of the codebase are affected

2. Discovery Phase

Use search tools to find all occurrences:

# Find direct usage
chs find-code "ExactPatternName"

# Find imports/requires
chs search-imports "module-name"

# Find similar patterns
chs search-function "functionName"
chs search-class "ClassName"

# Find test files
chs find-file "*.test.*" | xargs grep -l "PatternName"

3. Impact Analysis

  • List all files that need changes
  • Identify potential breaking changes
  • Check for external dependencies

4. Migration Plan

Create a step-by-step plan:

  1. Update core implementation
  2. Update imports/exports
  3. Update all usages
  4. Update tests
  5. Update documentation

5. Execute Changes

For each file:

  • Make the change
  • Verify with your project's linter/type checker
  • Run related tests
  • Commit changes with meaningful messages

6. Verification

After all changes:

  • Run full test suite
  • Check for type/lint errors
  • Verify no broken imports
  • Review all changes

7. Documentation

Update any affected:

  • README files
  • API documentation
  • Code comments
  • Migration guides for breaking changes

Track progress and ensure nothing is missed!

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

refactor-assistant is a command published in the GitHub repository cassler/awesome-claude-code-setup (267 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 346 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
