​
Skills and ClawHub

Skills are modular capabilities that extend what your UltraClaw agent can do. Think of them as plugins — each skill teaches your agent a new ability, from searching the web to managing complex workflows.

​
Bundled Skills

Every UltraClaw agent ships with a set of bundled skills that work out of the box — no setup required.

Web Search

Search the internet for real-time information, news, documentation, and research.

Web Browsing

Read and extract content from web pages, articles, and documents.

File Management

Create, read, and manage files in your agent’s workspace.

Code Execution

Write and run code to process data, perform calculations, or automate tasks.

Image Analysis

Analyze images you send — read text, describe scenes, extract data from screenshots.

Task Management

Track to-do items, set reminders, and manage projects within your workspace.
These bundled skills are always available and require no configuration.

​
ClawHub Marketplace

ClawHub is the community marketplace for UltraClaw skills. Browse and install skills created by the UltraClaw team and community to add new capabilities to your agent.

​
Custom Skills

Want your agent to do something specific to your workflow? You can create custom skills using the SKILL.md format. A custom skill is a markdown file that defines:
  • What the skill does — a clear description your agent uses to understand when to apply it
  • How to use it — step-by-step instructions your agent follows
  • When to activate — triggers or conditions that tell your agent when this skill is relevant
# Skill: Weekly Client Report

## Description
Generates a weekly summary report for a specific client,
pulling data from Google Sheets and QuickBooks.

## Instructions
1. Look up the client in Google Contacts
2. Pull this week's time entries from Google Sheets
3. Pull outstanding invoices from QuickBooks
4. Generate a formatted summary with hours, costs, and status
5. Save the report to Google Drive

## Trigger
When the user asks for a "client report" or during the
Monday morning cron job.
Custom skills are just markdown files in your workspace. Ask your agent to help you write one — describe what you want, and it’ll create the SKILL.md file for you.

​
Skill Priority

When multiple skills could apply, your agent uses this priority order:
1

Workspace Skills (Highest Priority)

Custom skills you’ve created in your workspace. These always take precedence because they’re tailored to your specific needs.
2

Managed Skills

Skills installed from ClawHub. These extend your agent’s capabilities with community-built functionality.
3

Bundled Skills (Lowest Priority)

The default skills that ship with every UltraClaw agent. Always available as a fallback.
This means you can override any bundled or managed skill by creating a workspace skill with the same purpose — your version always wins.

​
Managing Skills

From your dashboard, you can:
  • View installed skills — see what’s active on your agent
  • Enable / disable skills — toggle skills without uninstalling them
  • Uninstall ClawHub skills — remove skills you no longer need
  • Upload workspace skills — add custom SKILL.md files directly
Skills don’t consume additional tokens just by being installed. They only use tokens when your agent actively invokes them during a conversation.
