What are skills?
How do I open a .skill file?
Why use skills instead of relying on the base AI?
Is it safe to install skills?
What does a skill include?
When does an agent use a skill?
Do skills only work for coding?
Which platforms support skills?
What's the deal with frontmatter?
--- markers. It holds the metadata the agent reads before anything else: name, description, sometimes version, license, allowed tools. Get it wrong and the agent won't trigger the skill when it should. The spec lists every field.What are the rules for the skill name?
name field is lowercase, uses hyphens (no spaces, no underscores), sticks to letters, digits, and hyphens, and caps out at 64 characters per the Agent Skills spec. Treat it like a URL slug: "pdf-form-filler" works, "My Cool Skill!" does not. The name has to match the folder name exactly.What should the description include?
Can a skill bundle contain multiple SKILL.md files?
office/ (one sub-skill each for docx, pptx, xlsx, and pdf) or accounting workflows where every procedure has its own quirks.
