What it does
API Docs Writer is an agent skill from zhuyansen/agent-skills-hub. Write reference documentation for an HTTP endpoint from its handler code: parameters, responses, errors.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Technical documentation. The repository describes itself as: Discover and compare open-source Agent Skills, tools & MCP servers — with quality scoring, trending analysis, and automated GitHub sync. The licence is MIT.
When your agent uses it
- Tasks that involve Technical documentation
Example prompts
- “/api-docs-writer”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Read the input the user points to. If none is given, ask for the file or text.
- Do the task described above, step by step, and keep the user's own wording where it matters.
- Show the result, then a short list of what you changed or found, so the user can check it.
What it can do on your machine
Read from SKILL.md and the folder at commit 2862275. 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
No scripts in the folder and no shell commands in SKILL.md.
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 Docs Writer loads about 198 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 115 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
The full file from zhuyansen/agent-skills-hub at commit 2862275, republished under its MIT licence (© zhuyansen). 115 words, ~198 tokens.

When to use

Steps
