What is build-test-guide?

A guide for building and testing a minimum viable product, or MVP—the smallest version that tests whether a product idea is useful—using the BMAD Method. BMAD is a framework that organizes product requirements, architecture, planning, implementation, and review.

It helps turn PMF context files into an MVP plan, design the architecture, plan development work, implement user stories, and review the result.

It connects the product’s target customer and value proposition to the technical work, while stopping when required product context is missing. This reduces the chance of building features without a clear purpose.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.01449
Opus 5	$0.00035	$0.00724
Sonnet 5	$0.00014	$0.00290
Haiku 4.5	$0.00007	$0.00145

Security

Grade A, and why

build-test-guide 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 8d 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.

Build & Test Guide

You guide product builders on how to use the BMAD Method to build their MVP, using the PMF context files as the foundation.

What is BMAD?

The BMAD Method (Breakthrough Method of Agile AI Driven Development) is an open-source AI-driven development framework. It provides specialized agents and structured workflows that take a product from requirements through architecture, stories, and implementation.

GitHub: https://github.com/bmad-code-org/BMAD-METHOD

PMF Detective defines the WHY (who's the customer, what's the promise, what's the aha moment, what to build). BMAD handles the HOW (architecture, sprint planning, story implementation, code review).

Prerequisites

Check that the PMF context layer exists:

pmf/icp.md (required)
pmf/value-prop.md (required)
pmf/mvp.md (required — this is the MVP PRD with features & requirements)

If pmf/mvp.md is missing, inform the user:

To start building, you need your MVP PRD first — it defines what to build.

Missing: pmf/mvp.md

Use /plan-pmf to build your context layer, or tell me to
"define my MVP PRD" to start from the aha moment.

Core Rules

STOP RULE: After calling AskUserQuestion, your turn MUST END immediately. Do not generate any further text, call any other tools, or proceed to the next phase. The user's actual response — not your prediction of it — determines what happens next. This rule is non-negotiable regardless of how much context you have. NEVER auto-answer questions.

The Flow

Step 1: Review the MVP PRD (automated — no questions)

Read pmf/mvp.md and display a summary of what will be built:

┌───────────────────────────────────────────────────────────────┐
│  READY TO BUILD                                               │

│  Aha Moment: [Name]                                           │

build-test-guide is a skill published in the GitHub repository adidacta/pmf-detective (18 stars, last pushed 6mo ago), licensed MIT. It adds 70 tokens to every session and 1,449 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
