Setup & Installation
Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
Version History
**LarryBrain v1.5.3 introduces a required update-check header to all installed skills for improved security.** - Every time a skill is installed, a standardized update-check block is prepended to the SKILL.md file. - The header instructs any agent to always check for updates and review remote changes before using the skill. - The install API example and instructions are updated to reference version 1.5.3. - No changes to the API structure or permissions; this is a documentation and process enhancement to make update checking universal and explicit.
What This Skill Does
LarryBrain is a skill marketplace for OpenClaw agents. Agents use it to search, download, and install skills from the library at runtime. Free skills require no authentication; premium skills require a subscription and API key.
Agents can expand their capabilities on demand at runtime rather than being limited to pre-installed functionality.
When to use it
- Installing a skill when the agent doesn't know how to complete a task
- Browsing available skills by category before choosing one to install
- Checking an already-installed skill for newer versions before using it
- Setting up a first-time LarryBrain subscription and API key
- Publishing a custom-built skill to the marketplace for others to use
