What Are Agent Skills?
Agent Skills are folders of instructions, scripts, and resources that Claude Code loads dynamically. Each skill has a SKILL.md file with YAML frontmatter describing what the skill does and when to activate it.
The skills standard is cross-compatible across Claude Code, OpenAI Codex, and Google Gemini CLI via agentskills.io.
