Claude Code Skills — Best AI Coding Skills for Claude Code CLI
What is Claude Code?
Claude Code is Anthropic's official command-line AI coding agent. It runs directly in your terminal, understands your entire codebase, and can autonomously plan and execute complex development tasks.
Unlike chat-based AI assistants, Claude Code operates as an agent — it reads files, writes code, runs tests, commits changes, and handles multi-step workflows with your approval.
Key Features
- Terminal-native: Runs in your shell, works with any project
- Full codebase awareness: Reads and understands your entire project
- Agentic execution: Plans multi-step tasks and executes them
- Tool use: Runs commands, edits files, searches code
- Agent skills: Load domain-specific knowledge via SKILL.md files
- MCP support: Connect to external tools and APIs
How Skills Work in Claude Code
Claude Code reads SKILL.md files to learn domain-specific knowledge. When you ask it to work on something covered by a skill, it automatically applies the right instructions.
