refactor

A code-refactoring workflow based on patterns associated with Martin Fowler, a software design author.

In plain words
What is it for?
It is for scanning selected code for refactoring opportunities, applying controlled improvements, and checking again for issues introduced by each change.
Why use it?
It finds readability, design, duplication, and unnecessary-abstraction problems before applying changes one at a time.

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 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/refactor

Scatter–gather: three parallel read-only detectors scan for smells, then a single serial fixer applies refactorings one at a time. Detectors never edit — only the fixer writes, and it re-scans cascades after each change, so the "one refactoring at a time" invariant is preserved.

Usage

/refactor                    # Analyze current code for smells
/refactor Email              # Create Email value object
/refactor UserService         # Refactor specific file

Workflow

  1. Identify the target file (and its tests / siblings). This determines which file-type checks apply (backend vs .tsx).
  2. Dispatch the detectors concurrently and await all of them — start every named agent before awaiting results, then gather every result. No dispatch is detached or fire-and-forget: step 3 requires the complete result set. Each runs only its cluster of .claude/templates/refactoring/scan-checklist.md and returns a candidate table:
    • refactor-mechanics-agent — cluster M (size, complexity, variables, dead code)
    • refactor-design-agent — cluster D (domain modeling, behavior placement, type safety)
    • refactor-duplication-agent — cluster T (sibling/cross-class duplication, tests, frontend)
  3. Gather + fix: hand all candidate tables to .claude/agents/refactor-agent.md (the serial fixer). It merges, dedups, orders highest-impact-first, applies ONE refactoring at a time (loading the template from the Code Smells Routing Table), runs tests, and re-scans cascades inline — repeating until clean.

Small-file shortcut

If the target is small with few methods/concerns, skip the fan-out and run a single refactor-agent pass over the whole checklist — the detector orchestration + merge overhead can exceed the single-agent cost on tiny files. Dispatch that lone pass and await its result. Here the fixer's report is this skill's entire output, so an unawaited call could report "refactored" before a file was touched.

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 is a skill published in the GitHub repository rakovi4/continue-framework (50 stars, last pushed 5d ago), licensed MIT. It adds 27 tokens to every session and 1,051 once invoked, about $0.0001 per session on Opus 5. 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.
