Frontmatter, Deep Dive
Know exactly what belongs in frontmatter — and what does not.
Frontmatter is the always-loaded part of a skill. Keep it tight: the more you put there, the more of every session it costs. Name and description carry the weight; everything else is body.
- name — stable, kebab-case, unique within the skills directory.
- description — the trigger surface (previous lesson).
- Keep procedural detail OUT of frontmatter — it belongs in the body, which loads only after the trigger matches.
