Skills from ClawHub accumulate over time. You install one for a project, forget about it. Months later it's outdated and possibly broken.
Run clawhub list to see everything you have installed. To update all installed skills at once, run clawhub update --all. If you want to update just one, use clawhub update <slug> with the skill's slug.
You can enable or disable skills in ~/.openclaw/openclaw.json or by asking OpenClaw directly in chat. Some skill changes may require a gateway restart to take effect.
If a skill causes problems after an update, openclaw plugins doctor reports the cause. Remove skills you no longer use. Unused skills slow down startup and can conflict with newer versions.
