core reference tool
Core is part of the MCP & Tools category — MCP and tooling skills that expose extra tools to your agent. You can install it on its own or alongside other mcp & tools skills from the OpenClaw catalog.

- Search for
coreand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Core with a single command:
openclaw skills add core
This pulls core from ClawHub and installs it into ~/.openclaw/skills/core/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Core
Once installed, Core activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Manual install (advanced)

core-3.0.0.zipdirectly from our S3 mirror. - Unzip into
