simplify SKILL.md skillA

simplify from riot-org/riot is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add riot-org/riot/simplify@git:20260817.d4dfa41

Pins git:20260817.d4dfa41 in mdr.lock. Pin the fingerprint instead.

功能跑通之后、交付之前的收尾清理。按复用、质量、效率三张清单过一遍刚改的代码并修掉发现的问题。只碰这次改动的范围，不搞漫游式重构。.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 收尾清理

时机：功能已经工作、验证已经过了。先圈范围：

```bash
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。

How to install

The exact contents, by fingerprint

mdr add riot-org/riot/simplify@sha256:cbb772316318f86e

The line at the top of this page pins the label git:20260817.d4dfa41, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
