Overview

The Skills Marketplace lets you browse, install, and manage AI agent skills from the skills.sh  ecosystem. Skills are .skill.md files (plus optional scripts) that provide specialized context and instructions to AI agents.

How Skills Work

A skill is a markdown file that gets injected into an agent’s context, giving it domain-specific knowledge and instructions. For example, a “React Testing” skill teaches agents best practices for writing React tests with specific patterns and libraries.

└── skill.json    # Metadata (name, version, tags)

Browsing the Marketplace

The Browse tab shows a curated registry of 12 skills from Anthropic, Microsoft, GitHub, and the community. Each skill card displays:

  • Name and author
  • Description and tags
  • Download count and star rating
  • One-click install button

Use the search bar and category filters to find skills:

Categories: Frontend, Backend, DevOps, Quality, Security, Documentation, Marketing, Custom

Installing Skills

  1. Navigate to Skills in the sidebar
  2. Find a skill in the Browse tab
  3. Click Install — the skill is downloaded and linked to your project
  4. The skill’s context is automatically included in agent sessions

Managing Installed Skills

The Installed tab shows all skills for the current project:

  • Toggle — Enable or disable a skill without uninstalling
  • Uninstall — Remove the skill entirely
  • View details — See the full SKILL.md content

Creating Custom Skills

Click Create Custom to write your own skill:

  1. Enter a name and description
  2. Write the SKILL.md content (agent instructions, patterns, examples)
  3. The skill is saved locally and marked as custom

Custom skills are great for encoding team-specific patterns, coding standards, or domain knowledge that agents should follow.
