Mdzilla

What it does

When your agent uses it

• Claude needs to:
• Browse documentation for a library
• Fetch docs from GitHub repos
• Export documentation to flat markdown files

Example prompts

• “read the docs”
• “check the documentation”
• “browse docs for X”
• “/mdzilla”

Requirements

• Node.js

Workflow steps

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

1. 1If it matches a navigation path → renders that page
2. 2Otherwise → searches titles and content

What it can do on your machine

Read from SKILL.md and the folder at commit 4b89d25. 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:

  • npx

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • h3.unjs.io

  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

Mdzilla loads about 761 tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 129 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~139

When it runs · the whole SKILL.md, loaded when a task matches

~761

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

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.

description

Browse, search, and export documentation from any source using the mdzilla CLI. Use when Claude needs to: (1) Read or browse documentation for a library, framework, or project, (2) Fetch docs from GitHub repos, npm packages, or websites, (3) Export documentation to flat markdown files, (4) Look up API references, guides, or usage examples from doc sites. Triggers: user asks to "read the docs", "check the documentation", "browse docs for X", "fetch docs from", "export docs", or references a docs site URL, npm package docs, or GitHub repo docs.

npx mdzilla <source> [query] [options]

npx mdzilla gh:unjs/h3 /guide/basics        # render a specific page
npx mdzilla gh:unjs/h3 router               # search for 'router'
npx mdzilla https://h3.unjs.io /guide       # render page from URL
npx mdzilla npm:consola --plain             # list all pages (plain)

npx mdzilla <source> --export ./fetched-docs

import { exportSource } from "mdzilla";

await exportSource("./docs", "./dist/docs");
await exportSource("gh:unjs/h3", "./dist/h3-docs");
await exportSource("npm:h3", "./dist/h3-docs", { plainText: true });
await exportSource("https://h3.unjs.io", "./dist/h3-docs");

import { Collection, resolveSource } from "mdzilla";

const docs = new Collection(resolveSource("./docs"));
await docs.load();

console.log(docs.tree); // NavEntry[] navigation tree
console.log(docs.flat); // FlatEntry[] flat list

const content = await docs.getContent(docs.flat[0]);
const results = docs.filter("query"); // fuzzy search
