Claude Skill
A markdown bundle that teaches Claude Code or Claude Desktop a domain-specific workflow on demand.
Definition
A Claude Skill is a folder containing a SKILL.md (with YAML frontmatter listing name, description, and triggers) plus references and scripts. When the user's request matches a skill's description, Claude loads it into context. Skills standardise reusable procedures — deploying a service, writing a blog post, reviewing a PR — without bloating every conversation's system prompt.
