At a glance

Generate API endpoint documentation from Express route files.

  • Works in 3 steps: Route Discovery（路由发现） → Route Analysis（路由分析） → Documentation Generation（文档生成）
  • The user asks to generate
  • SKILL.md covers 工作流程 — MANDATORY, Reference Files and Quality Checklist
  • Runs Python scripts from its folder; calls python3

What it does

API Generating is an agent skill from huangjia2019/claude-code-engineering. Generate API endpoint documentation from Express route files. Use when the user asks to generate, update, or review API docs for Express.js routes.

Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/detect-routes.py` and `templates/api-doc.md`).

It sits in Development, covering Technical documentation and REST APIs. It works with Express. The repository describes itself as: This repository demonstrates how to use Claude Code to do real engineering work, not just writing code. 本项目是极客时间专栏 《Claude Code 工程化实战》 的官方配套示例仓库，目标就是： 👉 把 Claude Code…

When your agent uses it

  • The user asks to generate
  • Review API docs for Express.js routes

Example prompts

  • “/api-generating”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, Bash(python *)

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Route Discovery（路由发现）
  2. Route Analysis（路由分析）
  3. Documentation Generation（文档生成）

What it can do on your machine

Read from SKILL.md and the folder at commit 89fea03. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Glob
    • Write
    • Bash(python *)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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

API Generating loads about 426 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 171 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~426

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 171 words (~426 tokens).
