Nova writes the PRDs, the roadmap, and the research plan. Kwasi Twum-Acheampong and Conrado Miranda review before you build.
You can build it faster than you can spec it, so you skip the spec. That works until the third rewrite, when it turns out the thing you built solved a problem two of your users had and none of them would pay for.
Nova is the product agent on your Marskel team. It writes PRDs structured for AI coding tools, so the spec goes straight into Claude Code or Cursor without translation. It turns customer conversations into a prioritized backlog. It builds the research plan, drafts the interview script, and synthesizes what you heard into something you can act on. It maintains the roadmap so it reflects decisions rather than wishes.
Kwasi Twum-Acheampong and Conrado Miranda review Nova's work. Product is where a second opinion earns the most, since the expensive mistake is not a bad feature spec but a well-specified feature nobody needed. Reviewers push back on the premise, not just the document.
