Claude Skill

The PRD Writer

Turn a rough idea into a spec a team can build from, without a meeting to decode it. It drafts, critiques its own draft against a rubric, and rewrites the weak parts before you ever see it.

Two loops. The writer loop drafts, scores itself against a rubric, and fixes what falls short, so the version you read is already the third one. The learning loop reads the edits you made and your team's feedback, then proposes changes to how future specs get written. It reads your context.md if you have one, so it starts from your product and your standards instead of a blank page. The more you use it, the more it writes like you.
