It is a **rewrite** workflow: it never adds or removes entries, never changes URLs, titles, tags, or order. For adding new URLs use `mt-add-url`. + +This skill handles: posts under `content/post/**/index.md` whose frontmatter `categories` contains `Newsletter`. It does **not** handle: regular blog posts, reviews, tag changes (`mt-add-tags`), or new content. + +Shared engine: `scripts/newsletter/` ([engine-commands.md](../../../docs/newsletter/engine-commands.md)).
