markdocs

CLI to compile library documentation into Claude Code skill files

How It Works

markdocs add react does five things:

1. Asks the configured LLM for official documentation URLs
2. Lets you pick which URL(s) to scrape (interactive)
3. Scrapes the page with a built-in Go scraper (no external APIs)
4. Compiles the content into a structured skill file using the LLM
5. Writes .claude/skills/frontend/react.md — Claude Code picks it up next session

Installation

1. Using go:

go install github.com/Nithin-Valiyaveedu/markdocs@latest

2. Using npm:

npm install -g @val-nithin/markdocs

3. Using brew (Mac/Linux):

brew tap Nithin-Valiyaveedu/markdocs
brew install markdocs

Quick Start

# 1. Configure your LLM provider (runs once)
markdocs init

# 2. Add a skill for any library
markdocs add shadcn
markdocs add stripe
markdocs add drizzle-orm

# 3. Scan your project for missing skills
markdocs scan

# 4. Keep skills up to date
markdocs update --all

Commands

markdocs init

Interactively configure an LLM provider. Auto-detects from environment variables (ANTHROPIC_API_KEY, OPENAI_API_KEY) or a local Ollama instance.

Supported providers:

• Anthropic (Claude)
• OpenAI (GPT)
• OpenAI-compatible (Groq, Together AI, any custom endpoint via base URL)
• Ollama (local, auto-detected at localhost:11434)

Config is saved to ~/.markdocs/config.json.

---

markdocs add <library>

Find, scrape, compile, and write a skill file for the given library.

markdocs add react
markdocs add shadcn
markdocs add stripe --no-interactive

Flags

Flag	Description
--no-interactive	Skip URL selection prompt, use first suggested URL

The skill is written to .claude/skills/<category>/<library>.md in the current directory.

---

markdocs scan

Detect libraries in the current project that don't have skill files yet. Reads package.json, go.mod, and requirements.txt.

markdocs scan
markdocs scan --add-all

Flags

Flag	Description
--add-all	Automatically add skills for all missing libraries

---

markdocs list

Show all compiled skills for the current project.

markdocs list
markdocs list --stale

Flags

Flag	Description
--stale	Show only skills compiled more than 7 days ago

---

markdocs update [skill]

Recompile skills whose source documentation has changed (detected via checksum comparison).

markdocs update react
markdocs update --all

Flags

Flag	Description
--all	Check and update all skills

Skill File Format

Skills are plain Markdown with YAML frontmatter. All metadata is stored in the file itself — no database.

Scraper

markdocs uses a built-in two-layer scraper — no external scraping APIs required:

• Layer 1 — net/http + go-readability (works for most static doc sites)
• Layer 2 — go-rod headless browser fallback (JS-rendered sites like Chakra UI, Radix)

Layer 2 requires Chrome or Chromium to be installed.

Use as a Claude Code Skill

npx skills add Nithin-Valiyaveedu/markdocs

Or copy skills/markdocs/SKILL.md into your project's .claude/skills/ directory.
