refactor-bulk

refactor-bulk is a skill for Claude Code from forest6511/claude-code-recipes-v2. It costs 25 tokens per session (242 once invoked), scanned A, original, MIT.

A directory-wide refactoring process that applies a named code pattern to matching files. Refactoring changes the code’s structure without intending to change what it does.

In plain words
What is it for?
Finding all candidates for a specified refactoring, estimating their impact, applying the changes one file at a time, and summarizing the modified files and test results.
Why use it?
It helps handle repeated improvements in a controlled order, from smaller changes to larger ones. Tests are run after each file is changed.

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-bulk 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 5d 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

対象ディレクトリ: $0 適用するリファクタパターン: $1

タスク

  1. ディレクトリ配下の全ファイルから、指定パターン ($1) の適用候補を網羅的に列挙
  2. 候補を変更が小さいものから大きいものへ並べ、影響範囲を見積もる
  3. 1ファイル単位でリファクタを実行し、各ファイル変更後にテストを実行
  4. 全候補処理後、変更ファイル一覧と各テスト結果を要約してメインに返す

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.
