An agent skill is a directory containing SKILL.md with YAML frontmatter. At session start Claude Code loads only the name and description from that frontmatter into the system prompt. The body of SKILL.md, and any additional files the skill ships, are read only when the skill is invoked. This progressive disclosure is what makes it cheap to have many skills installed.
The practical consequence is that the description is the entire basis for the model deciding whether the skill is relevant. A description that says what the skill is rather than when to use it will not fire. Write it as trigger conditions, including the words a user would actually type.
When a skill is not activating, the fix is almost always in the description rather than in the body. Test by starting a fresh session and phrasing a request the way a real user would, instead of naming the skill explicitly, which bypasses the discovery path you are trying to test.
