What it does

External System Debugging is an agent skill from doccker/cc-use-exp. 涉及浏览器、编辑器、CDN/WAF、IM 平台、操作系统剪贴板、第三方 SaaS 等"外部黑盒系统"的代码编写或 bug 调试时触发。强制先抓真实环境数据再推理,避免连续 2 轮"凭代码推理"的修复 no-op。关键词:粘贴/复制异常、跨平台显示不一致、第三方 API 怪结果、CDN/WAF 拦截、本地复现失败、HTML→MD 转换丢属性。

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/case-csdn-paste-list.md`, `references/case-http-cdn-waf.md` and `references/case-proxy-keyword-misjudge.md`).

It sits in Development, covering Debugging. The repository describes itself as: ⛔ No longer maintained → dev-agent-kit/recipes 让 Claude Code、Antigravity、Gemini CLI、Codex、Cursor 开箱即用的分层配置模板,总结十多年的日常开发经验.

When your agent uses it

  • Tasks that involve Debugging

Example prompts

  • “外部黑盒系统”
  • “/external-system-debugging”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. 不要跳过数据采集:用户描述的现象可能不准确,真实数据才是事实
  2. 假设必须基于数据:每个假设都要能引用具体的抓取结果,不能"我以为"
  3. 单变量验证:一次只改一个变量,验证假设
  4. 修复后必须沉淀:追加新案例到 references/case-{name}.md

What it can do on your machine

Read from SKILL.md and the folder at commit 64470cb. 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:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    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

External System Debugging loads about 823 tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 258 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~823
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.3k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 258 words (~823 tokens).
