Skills are modular capability files (~/.claude/skills/[name]/SKILL.md) that load into the current conversation when triggered by keyword matching. Unlike commands (which you invoke explicitly), skills activate automatically when the conversation context matches their description.
This is the key difference from agents: skills run in your current context, sharing everything the conversation already knows. Agents run in isolation. For most work, skills are the better primitive.
