What Is ClawHub? A Guide to the OpenClaw Skills Registry

Quick Answer

ClawHub is the official public skills registry for OpenClaw. It hosts over 13,700 community-built skills that you can install in a single command to extend what your agent can do — from productivity integrations and browser automation to database queries, email handling, and creative workflows. Think of it as an app store for your AI agent.

What Problem Does ClawHub Solve?

Out of the box, OpenClaw can search the web, read files, run commands, and chat. These are powerful base capabilities, but they're general-purpose. The moment you want your agent to do something specific — check your Google Calendar, add items to Notion, summarise a YouTube video, send you a daily briefing — you need a skill that teaches it how.

Before ClawHub, people were sharing skills as raw files in GitHub repos, Discord channels, and forum posts. Finding the right skill meant searching across multiple platforms, checking compatibility, and hoping it actually worked. ClawHub centralises all of this into one searchable registry with versioning, reviews, and automatic security scanning.

How ClawHub Works

ClawHub is both a website you can browse and a CLI tool you install alongside OpenClaw. The CLI is how you actually install and manage skills on your agent.

Installing the CLI

If you haven't already:

npm i -g clawhub

This gives you the clawhub command, which handles searching, installing, updating, and removing skills.

Searching for Skills

You can search directly from your terminal:

clawhub search summarize

clawhub search notion

clawhub search weather

Each result shows the skill name, a short description, the author, install count, and a rating. You can also browse the full catalogue on the ClawHub website, which shows more detail including screenshots, documentation, and user reviews.

Installing a Skill

Once you find something you want:

clawhub install [skill-slug]

The skill downloads and registers with your OpenClaw agent. Restart your agent (or it'll pick it up on the next cycle) and the new capability is live. Most skills work immediately with no additional configuration.

Updating Skills

Skill authors push updates to fix bugs and add features. To update a specific skill:

clawhub update [skill-slug]

Or update everything at once:

clawhub update --all

Removing Skills

If a skill isn't working out or you want to keep things lean:

clawhub uninstall [skill-slug]

What Kinds of Skills Are Available?

The registry is organised into categories, and the range is broader than most people expect. Here are the main categories and what's in them.

Productivity

Integrations with tools like Notion, Todoist, Obsidian, Google Calendar, Outlook, and Trello. These let your agent read and write to the systems you already use for work. The Summarize skill — one of the most popular on ClawHub — also falls in this category.

Web and Research

Skills that enhance your agent's ability to find and process information online. Agent Browser reads full web pages (not just search results). Deep Research skills can search multiple sources and synthesise findings into reports. RSS and news monitoring skills track topics over time.

Communication

Skills for managing email, drafting messages, and integrating with communication platforms beyond the channels OpenClaw already supports natively.

AI and Machine Learning

The Capability Evolver skill — ClawHub's top-rated in this category — lets your agent learn new tasks iteratively. Other skills in this area include image generation integrations, transcription tools, and model-switching utilities.

Developer Tools

GitHub integration, code review helpers, documentation generators, and deployment scripts. Useful for developers who want their agent involved in their engineering workflow.

Home and Lifestyle

Weather, smart home integrations, fitness tracking, recipe management, and location-based services. These are particularly popular for personal agents that run on WhatsApp or Telegram.

How Skills Are Built

This is one of the most interesting things about the OpenClaw ecosystem. Skills are essentially markdown files with a specific structure. They contain instructions that teach your agent how to perform a task — what tools to use, what steps to follow, what format to produce output in.

Because they're plain text, they're easy to read, easy to modify, and easy to create from scratch. You don't need to write traditional code. If you can describe a process clearly in natural language, you can probably write a skill. The OpenClaw documentation has a full authoring guide, and many people start by modifying an existing skill to suit their needs rather than building from zero.

Once you've built a skill, you can publish it to ClawHub for others to use. The process is straightforward: create a ClawHub account, submit your skill through the CLI, and it goes through automated review before being listed.

Security

Skills run within your agent's permissions, which means a malicious skill could potentially access anything your agent can access. ClawHub takes this seriously.

Since February 2026, all skills submitted to ClawHub go through automatic VirusTotal scanning. This blocks known malicious patterns before they reach the registry. Skills also have public review counts and ratings, which provide a community layer of trust — widely-installed, well-reviewed skills are much more likely to be safe than obscure, unreviewed ones.

Best practices for staying safe: install skills from authors with a track record, read the skill description and understand what it does before installing, check the review count and rating, and be cautious with any skill that asks for credentials or access to sensitive accounts. These are the same precautions you'd apply to any software you install on your machine.

Frequently Asked Questions

Is ClawHub free?

Yes. Browsing, searching, installing, and updating skills is free. Some individual skills are marked as premium by their authors and may have a cost, but the vast majority are free.

Do I need ClawHub to use OpenClaw?

No. OpenClaw works without any skills installed — it has capable base functionality built in. ClawHub is optional but recommended, because it's where the community has built most of the specific integrations and workflows that make OpenClaw genuinely useful day-to-day.

How do I know if a skill is safe?

Check the install count, rating, and reviews. Skills that have been widely installed and positively reviewed are the safest bet. Avoid installing skills with zero reviews or from unknown authors without reading the source first. ClawHub's automated scanning catches known threats, but common sense is still your best defence.

Can I modify a skill after installing it?

Yes. Skills are markdown files on your local filesystem. You can open them, read them, and modify them to suit your needs. Many people use popular skills as a starting point and customise them for their specific workflow.

How often are new skills added?

The registry is growing rapidly. As of early 2026, there are over 13,700 skills, and new ones are submitted daily. The ecosystem is driven by the community, so growth correlates with OpenClaw's overall adoption — which is accelerating.

Can I use skills from ClawHub with NanoClaw or ZeroClaw?

Not directly. ClawHub skills are built for the OpenClaw skill format. NanoClaw and ZeroClaw have different architectures. Some skills may be adaptable with modification, but there's no plug-and-play compatibility between frameworks.
