bmad-prd

Invoke the skill with your product idea and any existing inputs like research or briefs. It runs a brain dump, calibrates stakes, offers a fast or coaching working mode, then drafts the PRD with tagged assumptions and finalizes it through a reviewer gate.

Use the Validate intent, which critiques the PRD without changing it. A rubric-walker subagent scores seven dimensions such as decision-readiness and done-ness clarity, and a synthesis pass produces HTML and Markdown validation reports with severity-tiered findings.

It uses an Essential Spine covering vision, target users, glossary, features with globally numbered FRs, non-goals, MVP scope, success metrics, and assumptions. An Adapt-In Menu adds conditional sections like compliance, monetization, API contracts, or hardware constraints based on the product's concerns.

Yes, the Update intent reconciles the PRD against a change signal, extracts from the memlog and original inputs, and surfaces conflicts with prior decisions before applying changes. It can also resume prior in-progress runs detected in the output folder.

Yes, headless mode is documented in references/headless.md for non-interactive callers. It completes the intent without prompting and returns a JSON status payload with artifact paths, assumptions, open questions, and blocked reasons.

For express builds the skill itself redirects to bmad-build, one-pagers to bmad-product-brief, and idea vetting to bmad-prfaq. Hobby or solo projects get a lighter roughly two-page PRD rather than the full enterprise structure.
