code-simplify is a command for Claude Code from vinvcn/addyosmani-agent-skills-zh. It costs 24 tokens per session (259 once invoked), scanned A, original, MIT.

A code-review command that simplifies recently changed code or another chosen scope while preserving its behavior.

In plain words
What is it for?
Use it to improve code clarity and maintainability, with tests and a build run after each change.

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

code-simplify 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 7d 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.

在精确保留行为的前提下,简化最近变更的代码(或指定 scope):

  1. 阅读 CLAUDE.md 并学习项目约定
  2. 识别目标代码 — 除非指定了更广 scope,否则默认为最近变更
  3. 修改前理解代码目的、callers、edge cases 和 test coverage
  4. 扫描 simplification opportunities:
    • Deep nesting → guard clauses 或 extracted helpers
    • Long functions → 按 responsibility 拆分
    • Nested ternaries → if/else 或 switch
    • Generic names → descriptive names
    • Duplicated logic → shared functions
    • Dead code → 确认后移除
  5. 增量应用每个 simplification — 每次变更后运行 tests
  6. 验证所有 tests 通过、build 成功且 diff 干净

如果 simplification 后 tests 失败,revert 该变更并重新考虑。使用 code-review-and-quality review 结果。

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.
