What Are Skills?

Skills are modular extensions — typically markdown files — that teach AI agents new capabilities. Install a skill, and your agent automatically knows how to use a new tool, follow a specific workflow, or handle a domain-specific task.

Must-Have Skills

Skill	What It Does	Works With
ProofShot	Visual UI verification with browser recording	Claude Code, Cursor, Codex, Gemini CLI, Windsurf, Copilot
.NET Skills	C#, ASP.NET, and .NET tooling	VS Code Copilot, Claude Code
GitHub workflow	PR reviews, issue triage, CI/CD	All agents
Docker/K8s	Container management, deployment	Claude Code, Codex
Database skills	Schema management, query optimization	All agents
Testing skills	Auto-generate and run tests	Claude Code, Cursor

Where to Find Skills

• ClawhHub — Largest marketplace for AI agent skills
• LobeHub — 500+ skills with search
• GitHub — Search “agent skills” for community repos
• Microsoft — dotnet/skills for .NET developers

How to Install

Claude Code:

# Drop skill files into user or project directory
~/.claude/skills/my-skill/SKILL.md      # User-level (all projects)
.claude/skills/my-skill/SKILL.md        # Project-level

Cursor:

~/.cursor/rules/my-skill.mdc

Most modern skills include auto-installers that detect your agents and configure everything automatically.

Why This Matters

Skills turn general-purpose AI agents into specialized tools. Instead of prompting “how to deploy to Kubernetes” every time, a K8s skill gives the agent permanent knowledge of your cluster configuration, deployment patterns, and safety checks.
