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.
Memory
What it does: Stores facts across conversations. Without this, OpenClaw forgets everything when a conversation ends.
Why you need it: For assistants that should remember user preferences, past interactions, or ongoing projects.
Install threshold: High priority for personal assistants. Lower priority for customer support bots where fresh context is preferred.
Calendar Integration
What it does: Reads (and optionally writes) your calendar. Can check availability, summarize upcoming events, or schedule meetings.
Why you need it: Makes scheduling requests actually useful — "Am I free Tuesday at 2pm?" requires calendar access.
Install threshold: Install if you use the bot for scheduling. Review OAuth scopes carefully — read-only is safer than read-write for initial setup.
Useful But Optional Skills
These add value for specific use cases:
Email (Send/Read)
Useful for drafting and sending emails on command. High risk if misconfigured — review send permissions carefully. Consider read-only access initially.
Slack/Discord Integration
For bots that need to cross-post to other channels or pull context from other workspaces. Straightforward if you're already using these platforms.
Database Query (SQL/Supabase/Airtable)
Powerful for data-driven assistants that need to answer questions from your business data. Requires careful permission scoping — read-only is strongly recommended.
Code Execution
Lets OpenClaw run code snippets for calculations, data processing, or automation. High capability, higher risk. Only install from verified sources and run in sandboxed environments.
Image Generation
Integrates DALL-E, Stable Diffusion, or similar APIs. Useful for content creation workflows. Cost implications: image generation APIs can be expensive at volume.
What to Avoid
Any skill published in the last 30 days with fewer than 100 installs
New skills from unknown authors with no community validation. The ClawHavoc security audit found that new skills from new authors had the highest rate of security issues.
Skills that request more permissions than they need
A "weather check" skill should not need access to your file system. A "web scraper" skill should not need your email credentials. Permission creep is a red flag.
Abandoned skills (no updates in 12+ months)
OpenClaw's API evolves. Skills that haven't been updated break — sometimes silently. The skill appears to run, but returns empty results or errors.
Skills with private/obfuscated code
Every ClawHub skill should have a public repository. If the code is private or minified in a way that prevents reading, treat it as untrusted.
The silent failure problem
Malicious skills rarely announce themselves. They often appear to work correctly while running background processes. Normal operation + unexpected API billing is the most common symptom.
Building Your Skill Stack: A Practical Sequence
Week 1: Install Web Search and Memory only. Get comfortable with how the bot behaves.
Week 2: Add Document Reader. Point it at your most important documentation.
Week 3: Add one integration skill based on your primary use case (Calendar, Email, or Slack).
Week 4+: Evaluate specific skill additions based on gaps you've noticed.
This staged approach means you can attribute any unexpected behavior to the most recently added skill — rather than having 15 skills installed simultaneously and no way to know which one is causing a problem.
The Curated vs. Open Marketplace Trade-Off
Self-hosted OpenClaw gives you access to all 11,000+ skills on ClawHub. You evaluate each one yourself.
Clawfleet's marketplace includes a curated subset: skills that have passed static analysis, VirusTotal scanning, sandboxed execution testing, and outbound traffic review. Fewer options, but each one verified.
For most business users, the curated approach is worth the trade-off. You're not losing access to the skills you actually need — you're losing access to the skills you should probably be skeptical of anyway.
