For people publishing skills: turn a process into a skill, test whether its description fires, write the pack README and release notes. Free.
Use when a pack is ready to list and someone asks for the README, store page, or buyer summary. Writes who it's for, one line per skill, and what buyers need.
Use when a new pack version ships and someone pastes a diff or a list of changes and asks for release notes. Writes what changed for the buyer, nothing more.
Use when a skill won't fire, or someone asks if a description matches what buyers type. Tests eight buyer phrasings and rewrites the description till they hit.
Use when someone wants to turn a process into a skill, or asks how to write a SKILL.md. Asks five questions, then writes the full file with frontmatter.
First release. Four skills for people publishing skills: write a skill from a process, check whether its description fires, write the pack README, write release notes.
