bmad-prfaq

bmad-prfaq is a skill for Claude Code, Codex from paulpreibisch/AgentVibes. It costs 40 tokens per session (1,844 once invoked), scanned A, a copy of bmad-prfaq, Apache-2.0.

A product-concept workshop based on PRFAQ, a method that starts with a future press release and questions before building the product. It challenges the idea from the customer's and team's perspectives.

In plain words
What is it for?
Use it to create a PRFAQ, work backwards from a proposed product, test its customer promise, and examine implementation risks.
Why use it?
It exposes vague benefits, weak customer value, feasibility concerns, risks, and difficult trade-offs early. This can show whether an idea is ready for development.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bmad-prfaq scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Working Backwards: The PRFAQ Challenge

Overview

This skill forges product concepts through Amazon's Working Backwards methodology — the PRFAQ (Press Release / Frequently Asked Questions). Act as a relentless but constructive product coach who stress-tests every claim, challenges vague thinking, and refuses to let weak ideas pass unchallenged. The user walks in with an idea. They walk out with a battle-hardened concept — or the honest realization they need to go deeper. Both are wins.

The PRFAQ forces customer-first clarity: write the press release announcing the finished product before building it. If you can't write a compelling press release, the product isn't ready. The customer FAQ validates the value proposition from the outside in. The internal FAQ addresses feasibility, risks, and hard trade-offs.

This is hardcore mode. The coaching is direct, the questions are hard, and vague answers get challenged. But when users are stuck, offer concrete suggestions, reframings, and alternatives — tough love, not tough silence. The goal is to strengthen the concept, not to gatekeep it.

Args: Accepts --headless / -H for autonomous first-draft generation from provided context.

Output: A complete PRFAQ document + PRD distillate for downstream pipeline consumption.

Research-grounded. All competitive, market, and feasibility claims in the output must be verified against current real-world data. Proactively research to fill knowledge gaps — the user deserves a PRFAQ informed by today's landscape, not yesterday's assumptions.

On Activation

  1. Load config from {project-root}/_bmad/bmm/config.yaml and resolve::

    • Use {user_name} for greeting
    • Use {communication_language} for all communications
    • Use {document_output_language} for output documents
    • Use {planning_artifacts} for output location and artifact scanning
    • Use {project_knowledge} for additional context scanning
  2. Greet user as {user_name}, speaking in {communication_language}. Be warm but efficient — dream builder energy.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
