Built-in Skills Tour

Last October when I first opened OpenClaw and saw the Skill list, I was completely overwhelmed — 49 built-in, plus thousands from the community. No idea where to start. Took me most of a day to realize only about a dozen are commonly used. The key is knowing which one to reach for in which scenario.

How Big Is the Ecosystem?

OpenClaw Skills are basically apps on your phone — each one gives the AI a new capability. But there's an important concept to get straight first: Skills are not TypeScript code modules. They're SKILL.md Markdown files with YAML frontmatter. Yes, plain text. The YAML header defines metadata (name, description, permission declarations), and the Markdown body contains prompts and usage instructions. Clever design — you don't need to write code to develop a Skill.

Current ecosystem: 49 built-in Skills out of the box. 93 officially maintained. Community developers have contributed 3,200+ through ClawHub (with embedding-based semantic search for easy discovery). Add 13,000+ MCP Servers on top of that — over 16,000 total.

Intimidating numbers, right? Don't worry about it. Master the built-in ones first.

Built-in Skills by Category

File Management

This category gets the most use from me. file-search does intelligent search — things like "find all PDFs modified last week." file-organize auto-sorts files. "Organize the downloads folder by type" — one sentence, done. file-rename for batch renaming, file-convert for format conversion.

Community stats say file handling efficiency improves by roughly 81%. Your mileage varies depending on your baseline.

Web & Search

web-search for internet searches, web-browse for visiting and summarizing web pages, web-clip for web clipping, web-monitor for watching page changes.

Side note — someone in the community complained about web-monitor's update frequency. It defaults to checking once per day. Want higher frequency? You need to configure your own cron. The docs don't make this clear. Once a day is too slow for most monitoring use cases.

Calendar & Productivity

calendar-manage for calendar management — "add a meeting tomorrow at 3 PM," that kind of thing. screenshot-to-event is pretty cool — take a screenshot of an event poster and it goes straight to your calendar. Recognition accuracy is decent, though Chinese dates occasionally get parsed wrong. Fix it manually when that happens. reminder for smart reminders, todo-manage for task management.

Content Processing

pdf-analyze for PDF analysis, translate for translation, summarize for summaries, write-assist for writing help. These are pretty self-explanatory. Oh — translate handles long texts better than just throwing things at ChatGPT directly, because it processes text in chunks instead of stuffing everything in at once (which causes quality to tank in the second half).

Developer Tools

Developers will care about this group: code-run for executing code, git-assist for Git operations, api-call for API calls, shell-exec for Shell commands. shell-exec occasionally hits permission issues on macOS, especially with paths under /usr/local/. Lost half an hour on my M2 MacBook to this — turned out Homebrew's install path had changed.

Multimedia & Voice

image-gen for image generation, image-edit for image editing (background removal, etc.), voice-talk for voice conversation.

The voice capabilities have evolved rapidly — far beyond the initial version. Voice Wake (macOS/iOS) supports wake words to activate OpenClaw without opening the app or typing. Talk Mode (Android) is the corresponding voice interaction mode. Voice engine supports ElevenLabs (better audio quality) and system TTS (free). The macOS menu bar app also has a push-to-talk floating window — just hold a hotkey and speak.

Canvas Interactive Whiteboard

This isn't in the traditional Skill list, but it absolutely deserves its own mention. Canvas is a real-time interactive whiteboard where AI can push content. Key operations:

• A2UI push/reset — AI pushes UI to your device, or resets the canvas
• eval — Remotely execute code snippets in Canvas
• snapshot — Capture current Canvas state

Ask AI to create a data visualization and instead of giving you code to run yourself, it pushes the chart directly to your Canvas for real-time display. Supported on macOS, iOS, and Android.

Browser Automation

OpenClaw can launch a dedicated Chrome/Chromium instance to operate web pages on your behalf. Not a simple scraper — real browser automation. Login, fill forms, click buttons, take screenshots, extract data. Describe what you want in natural language, it handles the rest. Way easier to pick up than Puppeteer/Playwright, though less flexible.

Node Mode

Developers should pay close attention to this. With Node Mode enabled, OpenClaw exposes system-level capability interfaces:

• system.run — Execute system commands
• system.notify — Send system notifications
• canvas — Control the interactive canvas
• camera — Access the camera

Essentially turns OpenClaw into a system-level SDK with an AI brain. Great for automation scripts, CI/CD integration, and more.

Installing Community Skills

Three ways.

Via ClawHub (most common):

# Search skills
openclaw skills search "github"

# Install a skill
openclaw skills install github-pr-review

# Or use the clawhub command
clawhub install <skill-slug>

Via GitHub link — just drop a repo URL in the chat:

You: Install this skill https://github.com/xxx/openclaw-skill-xxx
Bot: ✅ Installed skill-xxx, ready to use!

Manual install — copy the Skill folder to the right directory:

# Global install
cp -r my-skill/ ~/.openclaw/skills/

# Workspace install (only available in current project)
cp -r my-skill/ ./skills/

Manual install can hit permission issues. If ~/.openclaw/skills/ doesn't exist, create it with mkdir -p first. I naively assumed the directory would auto-create itself.

Popular Community Skills

Rough popularity ranking (by ClawHub download stats):

1. LinkedIn Automation — automate LinkedIn tasks, clawhub install linkedin-auto
2. X/Twitter Scraper — 40+ Twitter tools, clawhub install x-scraper
3. ClawdTalk — phone/SMS integration, clawhub install clawdtalk
4. GitHub PR Review — automated code review, clawhub install github-pr-review
5. Notion Sync — bidirectional Notion sync, clawhub install notion-sync

Also popular: Spotify Control, Smart Home (HomeKit/Hue), Gmail Agent, Obsidian Sync, Calendar AI.

Skill Category Stats

The 3,200+ community skills are very unevenly distributed. Coding Agents & IDEs make up the biggest chunk — nearly a quarter. Web & Frontend is next, followed by DevOps & Cloud, Search & Research, and Browser Automation with a few hundred each. Then Productivity, AI & LLMs, Git & GitHub, Image & Video, Communication, and PDF & Documents with one to two hundred each.

Developer-contributed skills dominate. ClawHub's semantic search is solid — describe what you want in natural language and it finds relevant Skills. Way better than browsing categories.

A Note on Security

This needs mentioning. Community Skills have system-level permissions — file read/write, command execution, network access. ClawHub content is "curated, not audited" — meaning it's filtered but not professionally security-audited. Long-term, they'll need proper audit mechanisms.

A few security things to be aware of. The CVE-2026-25253 disclosed in early 2026 was a Skill sandbox escape vulnerability — malicious Skills could bypass permission restrictions and access the host system. It was patched quickly, but it shows the security model in this space is still maturing. More notorious is the ClawHavoc incident: someone uploaded a batch of normal-looking Skills to ClawHub that were secretly mining crypto and exfiltrating sensitive data. This caused a huge shock in the community. ClawHub has since strengthened its review process, but the lesson is real.

Before installing, review the source code. Check VirusTotal scan results on ClawHub. Test in a non-sensitive environment first. Use openclaw skills inspect <skill-name> to view source before installing. Running openclaw doctor helps too — it flags risky Skill configurations.

Someone in the community once found a malicious Skill making unauthorized external requests. Rare, but worth being careful about.

Choosing Skills by Role

Students: web-search + summarize for searching and summarizing papers, translate for foreign-language literature, calendar-manage for courses and assignments. That's enough.

Developers: github-pr-review for automated code review, code-run for quick code execution, git-assist for Git help. Install these three and you won't regret it — I use them daily.

Working professionals: gmail-agent for email auto-sorting and replies, notion-sync for knowledge base management, calendar-ai for smart scheduling.

Once you understand the built-in Skills and their capabilities, it's time to build your own.
