Skills.sh — Agent Skills Manager

The package manager for AI agent skills — powered by the skills.sh open standard.

Discover, install, and manage agent skills without leaving your IDE.
Browse the skills.sh marketplace, keep skills up to date, and share curated skill sets with your team — all from the sidebar.
Works across 11 AI coding agents including Claude Code, Cursor, Windsurf, Copilot, Codex, and more.

Works with VS Code · Cursor · Windsurf · Antigravity · VSCodium · any VSIX-compatible editor

Find and install a skill in seconds

Explore the marketplace — leaderboards, search, and skill details

Share skills with your team via skills.json

Features

Marketplace

• Search and browse skills from skills.sh with trending, all-time, and hot leaderboards
• One-click install via npx skills add in an integrated terminal
• Skill detail pages with install counts, security audits, and rendered SKILL.md documentation
• Open the marketplace in a full editor tab for more space

Installed Skills

• Card grid layout — visual cards with status indicators, grouped by source
• Auto-invoke control — toggle whether each skill can be auto-invoked by AI agents. By default, agents like Claude Code, Cursor, and Windsurf automatically invoke skills based on context — use the per-skill toggle to disable this for skills you want to invoke manually (/skill-name).
• Multi-agent awareness — see which AI tools have each skill (Claude Code, Cursor, Windsurf, etc.)
• Global (~/.agents/skills/) and project-level (.claude/skills/) scopes
• "My Skills" group for locally-authored custom skills
• SKILL.md preview (rendered Markdown) and raw file viewing
• Copy skill path to clipboard

Skill Updates

• Detect outdated skills using the GitHub Trees API
• Badge count in the TreeView title showing available updates
• Update individual skills or all at once
• Silent background update check on startup (configurable)

Launch Claude with Skill

• Start a Claude Code session with a specific skill pre-loaded
• Configurable target: terminal CLI or Claude Code extension panel

Team Sharing

Commit a skills.json manifest to your repo so every team member gets the same skills. When a collaborator opens the project, the extension detects any skills listed in the manifest that are missing locally and prompts to install them — no manual setup needed.

• Add or remove skills from the manifest via context menus
• Automatically detects missing skills on project open and prompts to install
• "Install from skills.json" to sync all listed skills in one click
• Commit skills.json to version control and share via git

Security & Documentation

• Browse security audit results from Gen Agent Trust Hub, Socket, and Snyk
• Read skills.sh documentation (Overview, CLI, FAQ) directly in the editor

Auto-refresh

• File system watcher detects external installs and removals
• Lock file monitoring (~/.agents/.skill-lock.json) for reliable detection on all platforms
• Re-scan on window focus (configurable)

Works Everywhere

This extension is VSIX-based and works with any compatible editor:

• VS Code
• Cursor
• Windsurf
• VSCodium (via Open VSX)

The extension scans skill directories for 11 AI coding agents (paths verified against the skills.sh CLI source):

Skills found in multiple agent directories are deduplicated and show agent badges in the sidebar.
