PRD Agent

A requirements writer grounded in your research, not invention

What does the PRD Agent do?

Every section you write must be grounded in the prior stages' artifacts, not invented from scratch.From the agent's actual system prompt

The PRD Agent translates the concept and research into a structured product requirements document, one section at a time behind an outline-approval gate. It works from four templates: ProductOS Standard, Amazon PRFAQ, Lean, and Enterprise or Regulated.

Because it writes against the actual ideation and research artifacts, every requirement traces back to evidence. In revision mode it makes targeted edits instead of rewriting, so an approved spec stays approved.

What tools does the PRD Agent use?

  • write_prd_section

    Writes one PRD section per call, the primary deliverable

  • load_constraints

    Loads the project's locked constraints before writing

  • ask_agent

    Consults the Research or Ideation Agent when a section needs evidence

  • web_search

    Fills small factual gaps without leaving the document

Every agent works from the same shared context. Describe your idea once and the whole team builds on it.
