Artifact: product brief

BMAD’s pre-PRD scoping document — brief.md (+ addendum.md), produced in the Analysis phase to capture the problem, audience, and boundaries of a prospective project before the requirements spec is written. It is one of the inputs the PRD workflow synthesizes; the brief scopes, the PRD specifies.

Two variants share this page:

• PRFAQ (prfaq-{project}.md, from bmad-prfaq) — an Amazon-style Working-Backwards press release + FAQ: write the launch announcement first, then stress-test whether the product could earn it.
• Forged idea (forged-idea.md, from bmad-forge-idea) — the hardened output of adversarially pressure-testing a concept “until it hardens, proves out, or dies cheaply.”

Produced by (backlinks)

• bmad-product-brief — the core brief.
• bmad-prfaq — the Working-Backwards variant.
• bmad-forge-idea — the pressure-tested variant.
• gstack-office-hours — YC-Office-Hours reframed product/design doc that feeds gstack’s plan reviews.
