ClawHub hosts over 700 community skills. To install one, run npx clawhub install skill-name. This downloads the skill into ~/.openclaw/skills/skill-name/ and verifies its SKILL.md frontmatter.
You can browse what's available with clawhub list and filter by category. When a skill author pushes an update, clawhub update pulls the latest version for every installed skill. If an update introduces a new dependency your machine doesn't have, the skill silently deactivates until you install the missing binary or set the required variable. Try installing one now and see it show up in your tool list.
