What it does

Refactor is an agent skill from vstorm-co/pydantic-deepagents. Refactor code to improve structure and maintainability

Its SKILL.md is about 290 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Refactoring. The repository describes itself as: Open-source, self-hosted Claude Code - a terminal AI assistant and the Python framework behind it. Tool-calling, sandboxed execution, multi-agent teams, skills, checkpoints… The licence is MIT.

When your agent uses it

  • Tasks that involve Refactoring

Example prompts

  • “/refactor”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Understand — Read all related code, run existing tests
  2. Plan — Identify what to change and why
  3. Execute — Make changes incrementally
  4. Verify — Run tests after each change

What it can do on your machine

Read from SKILL.md and the folder at commit 650b592. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Refactor loads about 285 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 122 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~16
When it runs · the whole SKILL.md, loaded when a task matches
~285

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Refactor

Improve code structure without changing external behavior.

Process

  1. Understand — Read all related code, run existing tests
  2. Plan — Identify what to change and why
  3. Execute — Make changes incrementally
  4. Verify — Run tests after each change

Common Refactoring Patterns

Extract
  • Long function → smaller focused functions
  • Repeated code → shared helper
  • Magic numbers → named constants
Simplify
  • Deep nesting → early returns / guard clauses
  • Complex conditionals → descriptive functions
  • Large classes → smaller focused classes
Rename
  • Unclear names → descriptive names
  • Inconsistent naming → consistent conventions
Reorganize
  • Related functions scattered → grouped in modules
  • Circular dependencies → dependency inversion

Rules

  • Never change behavior — tests must pass before and after
  • One refactoring type per commit
  • If tests don't exist, write them first
  • Don't refactor and add features in the same change
