simplify

simplify is a skill for Claude Code, Codex from caiwuu/Riot. It costs 57 tokens per session (598 once invoked), scanned A, original, MIT.

A final cleanup checklist for code that already works and has passed verification. It reviews reuse, code quality, and efficiency within the files changed for the current task.

In plain words
What is it for?
Use it before delivery to make focused cleanup changes, remove redundant comments or parameters, improve reuse, and run tests after each cleanup group.
Why use it?
It finds duplicated logic, unnecessary state, needless compatibility code, repeated work, and avoidable input or database operations without turning the task into a broad refactor.

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

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 3d 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

收尾清理

时机:功能已经工作、验证已经过了。先圈范围:

git diff --stat        # 这次到底动了哪些文件

[约束] 只清理这次改动碰过的代码。别处的烂代码记下来告诉用户, 不要顺手改——收尾变漫游重构,diff 就没法审了。

清单一:复用

  • 新写的函数仓库里是不是已经有了?搜同名、同义词、相邻目录的 utils。 手搓的字符串处理、路径拼接、防抖节流、类型守卫是重灾区。
  • 复制粘贴改两行的代码块,统一成一个带参数的。

清单二:质量

  • 冗余状态:能从现有状态推导的值不要再存一份——存两份就要同步 两份,忘了同步就是 bug。
  • 参数蔓延:给函数加到第 5、6 个参数时,该重构签名了。
  • 字符串当类型用:仓库里已有常量、枚举、union 的地方不要写裸 字符串。
  • 废话注释:解释「代码做了什么」的删掉(命名已经说了);叙述 本次改动的删掉(那是 commit message 的事)。只留「为什么这么做」 和代码表达不了的约束。
  • 只为这次改动服务的兼容垫片:没人用的旧签名、多余的重导出、 「以防万一」的分支。

清单三:效率

  • 重复计算、循环里的重复 IO、N+1 查询;
  • 相互独立的异步操作在串行等待(能并发的并发);
  • 无界增长:只进不出的缓存、数组、事件监听器;
  • 读整个文件只为用一小段、拉全量列表只为过滤出一条。

修的时候

  • 一次一类,每改完一批跑一次测试——清理不该改变行为,测试是 唯一的证明。
  • 发现不值得修的就跳过并说一句为什么(比如要大动干戈)。清单是 工具,不是任务。

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.

simplify is a skill published in the GitHub repository caiwuu/Riot (2 stars, last pushed 3d ago), licensed MIT. It adds 57 tokens to every session and 598 once invoked, about $0.0003 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 2026-08-31.
