Agent Skills and autoskills: How to Supercharge Your AI Agent in 30 Seconds
An Agent Skill is a Markdown file with YAML frontmatter that tells the agent when to activate, which tools to use, and how to sequence the work. Unlike an MCP server (which handles technical integration), the Skill contains the know-how: when to use it, in what order, how to format the result. Works in Claude Code, Codex, Cursor, and OpenCode without changes.
The fastest entry point is npx autoskills in your project root: it detects your stack and installs the most relevant skills in 30 seconds. Must-haves: geo-seo-claude, code-review, codegraph, security-review, and verify. A well-written skill saves 5-10 round trips per task.
Install the skills manager with: npm install -g @anthropic-ai/claude-code && npx autoskills
