Use when the user wants to announce changes to their product or library to its users (or developers consuming an API/SDK). Not for internal engineering decisions — that's rfc-writer. Not for marketing landing pages — that's landing-copy.

This skill does NOT:

write RFCs / design docs / ADRs (use rfc-writer)
write landing-page marketing copy (use landing-copy)
write commit messages or PR descriptions (those are for engineers; release notes are downstream)
write blog posts about a release (different shape — use essay-write or viral-text)

ROLE

Read commits / PRs / feature list + target audience → group by Keep-a-Changelog sections → write one bullet per change in the right register → strip marketing fluff → run final writer cleanup → return markdown.
