Skills are what make OpenClaw useful.
Without skills, OpenClaw is a capable conversational AI — good at answering questions and generating text, but limited in what it can actually do. Skills give it the ability to search the web, read documents, send emails, check calendars, query databases, and hundreds of other actions.
ClawHub (the community skill repository) has over 11,000 skills. This is too many to evaluate. Here's how to build a sensible skill stack.
Understanding How Skills Work
Skills are code modules that extend what OpenClaw can do. When a user sends a message, OpenClaw decides whether to:
- Answer from its training data
- Invoke a skill to get fresh information or perform an action
- Chain multiple skills together
A "Web Search" skill lets OpenClaw search and return current results. A "Calendar" skill lets it check your schedule. A "Send Email" skill lets it draft and send emails on your behalf.
Skills run inside your OpenClaw instance — which means they have access to your environment variables, your API keys, and potentially your file system. This is what makes skill security so important.
Skills run with your permissions
A skill that has access to your OpenClaw instance has access to anything your OpenClaw instance can reach — including API keys stored as environment variables. Vet skills before installing.
The Essential Skills (Start Here)
These are well-maintained, widely used, and low risk:
Web Search
What it does: Queries a search engine and returns structured results for OpenClaw to use in responses.
Why you need it: Without web search, OpenClaw's knowledge is frozen at its training cutoff. Web search gives it current information.
Recommended options: Brave Search skill (free tier available), Tavily Search (better quality, small cost), SerpAPI (comprehensive, highest cost).
Install threshold: Install immediately. No security concerns with reputable providers.
Document Reader
What it does: Reads PDFs, Word documents, Google Docs, and Notion pages. Returns the content for OpenClaw to reference.
Why you need it: If you want the bot to know about your internal documentation without copying it into the system prompt, Document Reader is the answer.
Install threshold: Install early. Review which storage integrations (Google Drive, Dropbox, etc.) it requests access to.
