Generate API Documentation

Generate API Documentation is a command for coding agents from luongnv89/claude-howto. It costs 11 tokens per session (164 once invoked), scanned A, original, MIT.

An API documentation generator that reads source code to describe API endpoints, functions, inputs, outputs, errors, and usage examples. An API is a defined way for software systems to communicate.

In plain words
What is it for?
Use it to create Markdown documentation with endpoint details, request and response formats, error information, and curl, JavaScript, or Python examples.
Why use it?
It turns details already present in code into organized reference material, reducing the need to write every endpoint description by hand.

Command

Part of the documentation plugin — 3 commands, 3 agents shipped together

About the project

luongnv89/claude-howto is a visual, example-based guide to Claude Code, a coding tool that supports agents, hooks, skills, slash commands, and MCP servers. Developers use it to learn Claude Code through practical workflows and copyable templates, including the commands, agents, skills, plugins, and instructions catalogued here.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/luongnv89/claude-howto/generate-api-docs
Clone the repo
git clone --depth 1 https://github.com/luongnv89/claude-howto

Or install documentation, the plugin that ships this one along with the rest of its 3 commands, 3 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Generate API Documentation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
