What it does when it runs

Long-form article writer. Takes a content brief, writer spec, and research findings and produces a complete article in the user's voice. Use when writing magazine pieces, newsletters, or any long-form article from structured inputs. Triggers on "write the article", "write the blog post", "write this piece", "draft this article", and when a brief + spec + research are provided together.
