At a glance
Validate API documentation against quality standards. An agent skill from huangjia2019/claude-code-engineering.
- Works in 3 steps: Load Quality Rules → Check Each Documentation File → Cross-Reference with Source
- You need to verify generated docs are complete and correct
- SKILL.md covers Input, Process and Output Format
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Quality Checking is an agent skill from huangjia2019/claude-code-engineering. Validate API documentation against quality standards. Use when you need to verify generated docs are complete and correct.
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `rules/doc-standards.md`).
It sits in Development, covering Technical documentation. 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
- You need to verify generated docs are complete and correct
- Tasks that involve Technical documentation
Example prompts
- “/quality-checking”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Load Quality Rules
- Check Each Documentation File
- Cross-Reference with Source
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:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
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
Quality Checking loads about 393 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 138 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 138 words (~393 tokens).
