✨ Key Features

• 📚 Massive Pre-Built Skill Library: 101,330 evidence-backed skills covering 62K+ research papers and 23K+ coding/tech sources — all searchable offline via FTS5-powered SQLite bundles.

• 🔧 Fully Automated Skill Pipeline: Give it a topic → it discovers sources → fetches & extracts text → generates skills with an LLM → validates quality → publishes. One command, zero manual work.

• 🔬 Evidence-First, Never Hallucination-Only: Every skill traces back to real web pages, academic papers, or code repositories with full provenance chains — metadata, quality scores, and source links included.

• 🌐 Multi-Source Intelligence: Integrates Tavily, GitHub, Baidu, Zhihu, XHS, StackOverflow, arXiv, PMC, PLOS, Nature, eLife — 10+ data source providers for comprehensive coverage.

• 🧠 LLM-Powered Quality Gates: Each skill is generated, validated, and scored by LLMs with configurable quality thresholds — ensuring high-signal, low-noise output at scale.

• ⚡ Drop-In Reusability: Download domain-specific SQLite bundles, skill-search any keyword, and get structured Markdown ready to feed into any AI agent, RAG pipeline, or knowledge base.

• 🏗️ Extensible Architecture: Modular source providers, LLM backends (OpenAI / Ollama), queue-based batch processing, and configurable domain rules — built to scale.

• 📦 21 Domain Bundles: From Linux sysadmin to PLOS biology, from web development to machine learning — organized, versioned, and individually installable.

📦 Installation

LangSkills supports Linux, macOS, and Windows. Python 3.10+ required.

Option A: pip install (recommended)

pip install langskills-rai

# Download skill bundles (auto-detect your project type)
langskills-rai bundle-install --auto

# Or install a specific domain
langskills-rai bundle-install --domain linux

# Verify
langskills-rai self-check --skip-remote

Option B: From source (for development / skill generation)

git clone https://github.com/LabRAI/LangSkills.git && cd LangSkills
python3 -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
playwright install chromium          # optional: Baidu/Zhihu/XHS sources
cp .env.example .env                 # fill OPENAI_API_KEY + OPENAI_BASE_URL
langskills-rai self-check --skip-remote

git clone https://github.com/LabRAI/LangSkills.git && cd LangSkills
python -m venv .venv && .venv\Scripts\activate
pip install -e ".[dev]"
copy .env.example .env               # fill OPENAI_API_KEY + OPENAI_BASE_URL
langskills-rai self-check --skip-remote

🤖 AI CLI One-Liner — Auto Setup

Copy the prompt below and paste it into Claude Code / Codex / Cursor / Windsurf — the AI agent will automatically clone, install, configure, and verify LangSkills for you.

Do the following steps in order. Do NOT skip any step.

1. Install langskills-rai from PyPI:
   pip install langskills-rai

2. Auto-detect my project and install matching skill bundles:
   langskills-rai bundle-install --auto

3. Run the self-check to verify everything is working:
   langskills-rai self-check --skip-remote

4. If self-check passes, run a quick smoke test — search the built-in library:
   langskills-rai skill-search "machine learning" --top 3

5. If I want to generate NEW skills (not just search), ask me for my
   OPENAI_API_KEY and OPENAI_BASE_URL, then set them as environment variables.

Done. Report the results of steps 3 and 4.

🦞 OpenClaw Integration

LangSkills is available as an OpenClaw skill — giving any OpenClaw-powered agent access to 101K+ evidence-backed skills.

Install from Claw Hub (coming soon):

clawhub install langskills-search

# LangSkills Search

Search 101,330 evidence-backed skills covering 62K+ research papers and 23K+ coding/tech sources — all offline via FTS5 SQLite.

## When to Use

- User asks for best practices, how-tos, or techniques on a technical topic
- You need evidence-backed knowledge (not LLM-generated guesses)
- Research tasks that benefit from academic or real-world source citations

## First-Time Setup

```bash
pip install langskills-rai
# Install all bundles (~1 GB) or pick a domain:
langskills-rai bundle-install --auto
```

## Search Command

```bash
langskills-rai skill-search "<query>" [options]
```

### Parameters

| Flag | Description | Default |
|:---|:---|:---|
| `--top N` | Number of results | 5 |
| `--domain <d>` | Filter by domain | all |
| `--min-score N` | Minimum quality score (0-5) | 0 |
| `--content` | Include full skill body | off |
| `--format markdown` | Output as Markdown | text |

### Example

```bash
langskills-rai skill-search "CRISPR gene editing" --domain research --top 3 --content --format markdown
```

## Reading Results

Each result includes: **title**, **domain**, **quality score** (0-5), **source URL**, and optionally the full skill body. Higher scores indicate stronger evidence chains.

## Available Domains

`linux` · `web` · `programming` · `devtools` · `security` · `cloud` · `data` · `ml` · `llm` · `observability` · `research-arxiv` · `research-plos-*` · `research-elife` · `research-other`

## Tips

- Use `--content --format markdown` to get copy-paste-ready skill text
- Combine `--domain` with `--min-score 4.0` for high-quality results
- Run `bundle-install --auto` in a project directory to install only relevant domains

🖥️ CLI Reference

All commands: langskills-rai <command> (or python3 langskills_cli.py <command> from source)

⚙️ Configuration

Master config: config/langskills.json — domains, URL rules, quality gates, license policy.
