ClawHub Skills Development: The Agent Playbook

About This Guide

The ClawHub Skills Development Guide explains how to extend OpenClaw with custom skills and publish them to ClawHub, the community skills registry. An OpenClaw skill is a self-contained module that defines a set of tools the agent can call, with a manifest file specifying the skill name, version, required configuration, and tool schemas. The guide covers setting up the OpenClaw skill development environment, writing a skill manifest in YAML, implementing tool handlers that receive structured inputs and return typed outputs, writing unit tests with the Lobster testing harness, and debugging skills with the OpenClaw inspector. You will also learn how to version your skills using semver, publish to ClawHub with the claw publish CLI command, and configure per-user settings that consumers of your skill can customize. A worked example builds a complete web scraping skill from scaffold to published package. The guide also covers monetization options available for skill authors through the ClawHub marketplace.
