What it does

Refactorer is an agent skill from hex/claude-council. A behaviour-preserving restructure is named: extract, rename, move, split a module, or remove duplication across three or more sites.

Its SKILL.md is about 980 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 Agent Workflows. The repository describes itself as: Claude Code plugin that asks several AI coding agents the same question and shows their answers side by side. Gemini, OpenAI, Grok, Perplexity, Kimi and any model OpenRouter… The licence is MIT.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/refactorer”

Workflow steps

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

  1. Restate the target shape in one or two sentences: what moves where, what
  2. Read the project's own instructions (AGENTS.md, CONTRIBUTING, lint and
  3. List every site the change touches: definitions, call sites, imports,
  4. Decide what counts as observable behaviour here: public API, CLI output,

What it can do on your machine

Read from SKILL.md and the folder at commit 23867e1. 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

Refactorer loads about 984 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 609 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~984

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.

Refactorer

Restructure code without changing what it does. The result should be simpler to read, with one way to do each thing and no leftover paths.

Scope the change

  1. Restate the target shape in one or two sentences: what moves where, what gets a new name, what gets merged.
  2. Read the project's own instructions (AGENTS.md, CONTRIBUTING, lint and format config) and match the existing style, even where you would choose differently.
  3. List every site the change touches: definitions, call sites, imports, re-exports, config keys, docs, tests, and string references such as reflection, routing tables or serialized names. Search broadly, then read each hit. A textual match is only a candidate.
  4. Decide what counts as observable behaviour here: public API, CLI output, file formats, wire formats, error messages, log lines other tools parse. Those must not change. If the requested refactor would change one, stop and report it.

Baseline

  • Run the tests that cover the touched code before editing. Record the command and result.
  • If tests already fail, record which ones and do not treat them as caused by you. Do not fix them unless the task says to.
  • If nothing covers the touched code, say so. Then choose the cheapest real check you can run before and after, such as the CLI command, a sample request or a build, and record it.

Edit

  • Edit site by site. Never apply a regex or mass replace to write code. The same text can mean different things in different places; only reading the site tells them apart. Search tools are fine for finding sites.
  • Update every caller in the same change. Delete the old path: no alias, shim, wrapper, re-export layer, deprecated copy, or commented-out code. Version control is the archive.
  • Exception: if the old name is a public interface with outside consumers, stop and report it. Compatibility is a decision for the owner, not for you.
  • Import from the defining module, not through a barrel file that hides where things live.
  • Unify duplication only where three or more sites share the logic. Two similar sites may be coincidence; leave them and note it.
  • Remove test-only production seams (exports, flags, injection hooks with no production caller) only when the task includes them.
  • Do not mix in behaviour changes, bug fixes, dependency bumps or formatting sweeps. Record anything you notice for the report.

Tests

  • Tests should pass unchanged. If a test fails because it asserts the old structure (an import path, a private function name, an internal call order) rather than behaviour, update it to the new structure and list it in the report.
  • If a test fails on behaviour, your refactor changed behaviour. Fix the refactor, not the test.
  • Never delete, skip or weaken a test to get a pass.

Verify

  1. Re-run the baseline commands and compare results. They should be the same.
  2. Run the build, type checker and linter the project uses.
  3. Search again for the old names and paths. No references should remain except in history or changelog files.

Evidence to record

  • The site list, with how many sites were changed.
  • Baseline and final results of the same commands.
  • Tests that changed, each with why the change is structural, not behavioural.
  • Leftover references, if any, and why they stay.

Stop conditions

Stop and report when the refactor would change observable behaviour, when an old name has outside consumers, when the baseline cannot be established, or when a site's meaning is unclear enough that you would be guessing.

Handoff

Report the new shape, the sites changed, the before and after results, the tests you changed and why, and the follow-ups you deliberately left out.
