About this skill
Benchmark is a skill in affaan-m/ECC (276k stars). Its SKILL.md is about 330 tokens. Licence: MIT.
What it can do on your machine
Read from SKILL.md and the folder at commit ef648e0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bundle
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Benchmark loads about 330 tokens when it runs. Until then it costs about 11 tokens; SKILL.md has 49 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

基准测试 — 性能基线及回归检测
使用场景
- 在 PR 前后测量性能影响
- 为项目建立性能基线
- 用户反馈"感觉变慢"时
- 发布前确保达到性能目标
- 对比不同技术栈的性能表现
工作原理
模式 1：页面性能
通过浏览器 MCP 测量真实浏览器指标：
1. 导航至每个目标 URL
2. 测量核心网页指标：
- LCP（最大内容绘制）— 目标 < 2.5 秒
- CLS（累积布局偏移）— 目标 < 0.1
- INP（与下一次绘制的交互）— 目标 < 200 毫秒
- FCP（首次内容绘制）— 目标 < 1.8 秒
- TTFB（首字节时间）— 目标 < 800 毫秒
3. 测量资源大小：
- 页面总重量（目标 < 1MB）
- JS 包大小（目标 < 200KB gzip 压缩后）
- CSS 大小
- 图片重量
- 第三方脚本重量
4. 统计网络请求数量
5. 检查阻塞渲染的资源模式 2：API 性能
对 API 端点进行基准测试：
1. 每个端点请求 100 次
2. 测量：p50、p95、p99 延迟
3. 追踪：响应大小、状态码
4. 负载测试：10 个并发请求
5. 与 SLA 目标进行对比模式 3：构建性能
测量开发反馈循环效率：
1. 冷构建时间
2. 热重载时间 (HMR)
3. 测试套件执行时间
4. TypeScript 检查时间
5. 代码检查时间
6. Docker 构建时间模式 4：前后对比
在变更前后运行以测量影响：
/benchmark baseline # 保存当前指标
# ... 进行更改 ...
/benchmark compare # 与基线进行比较输出结果：
| Metric | Before | After | Delta | Verdict |
|--------|--------|-------|-------|---------|
| LCP | 1.2s | 1.4s | +200ms | WARNING: WARN |
| Bundle | 180KB | 175KB | -5KB | ✓ BETTER |
| Build | 12s | 14s | +2s | WARNING: WARN |输出
将基线数据以 JSON 格式存储在 .ecc/benchmarks/ 中。通过 Git 追踪，便于团队共享基线。

Questions about Benchmark
How do I install Benchmark in Claude Code?
Run `npx skills add affaan-m/ECC --skill benchmark -a claude-code`. Or copy the skill folder (docs/zh-CN/skills/benchmark in affaan-m/ECC) into .claude/skills/benchmark in your project. Claude Code loads it when a task matches its description.
How do I install Benchmark in Codex?
Run `npx skills add affaan-m/ECC --skill benchmark -a codex`. Or copy the skill folder (docs/zh-CN/skills/benchmark in affaan-m/ECC) into .agents/skills/benchmark in your project. Codex loads it when a task matches its description.
Can I use Benchmark in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill benchmark -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/benchmark, .gemini/skills/benchmark, .github/skills/benchmark and .opencode/skills/benchmark in your project.
What does Benchmark need to run?
Going by SKILL.md and its folder, Benchmark needs the command-line tools its instructions call (bundle).
Does Benchmark access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Benchmark safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Benchmark use?
Benchmark is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Benchmark use?
About 330 tokens (SKILL.md is roughly 1.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Benchmark?
Skills that share tags, products or a category with Benchmark: Benchmark (androidx/androidx, 6.1k stars), Benchmark (samchon/typia, 5.9k stars), Gstack Performance Benchmark (garrytan/gstack, 136k stars) and Benchmark (zalando/skipper, 3.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Benchmark?
affaan-m (a GitHub user) maintains it in affaan-m/ECC, which has 275,546 GitHub stars. The repository holds 673 skills in this directory. The repository was last updated on October 5, 2026.
