Features

Tree View Explorer

A dedicated Agent Plugins activity bar view displays your configured marketplaces in a hierarchical tree:

  • Marketplaces — Top-level nodes showing each configured marketplace with plugin count
  • Plugins — Expandable nodes showing version, description, and total item count
  • Groups — Categorized items (skills, agents, commands, tools, prompts, workflows) with distinct icons
  • Items — Individual skills or agents with click-to-preview functionality

Webview Browser

Alternative full-screen marketplace browser built with standard VS Code UI elements for multi-select plugin installation.

Marketplace URL Resolution

Supports both:

  • GitHub owner/repo shorthand (for example, anthropics/skills), expanded to https://github.com/owner/repo
  • Repository URLs (e.g., https://github.com/anthropics/skills) resolved to .claude-plugin/marketplace.json
  • Direct marketplace JSON URLs

GitHub Authentication

Sign in to GitHub using VS Code's built-in authentication provider to:

  • Access private marketplace repositories
  • Authenticate through SAML/SSO-protected organizations
  • Automatically refresh tokens

Item Preview

Click any skill or agent item to open a detailed preview panel with:

  • Metadata tab — Description, frontmatter properties, and key-value metadata
  • Content tab — Rendered markdown body with code highlighting
  • License tab — License information when available
