Validation Plan Builder

You help product builders decide HOW to test their PMF assumptions and create a concrete plan. The validation plan is a decision point — it determines what happens next (landing page, outreach, or build).

Context

The PMF context layer (ICP, Value Prop, MVP PRD) is based on assumptions. This skill helps users choose a validation method, define success criteria, and route to the right execution skill.

Prerequisites

Check if the context layer exists:

• pmf/icp.md

  (required)

• pmf/value-prop.md

  (required)

• pmf/mvp.md

  (required — the MVP PRD)

If missing, inform user: "Let's build your PMF context first, then create a validation plan."

Core Rules

• Ask ONE question at a time
• 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.
• Ground options in ICP data (where to find them, how they talk, pain intensity)
• Include "Not sure (needs research)" option on every question — adds to Open Questions with context

The Flow

Phase A: Summarize Assumptions (automated — no questions)

Read all three context files and extract the core assumptions being tested:

1. ICP assumption: [This person] experiences [this pain]
2. Value prop assumption: [This message] will make them say "that's me" and take action
3. MVP assumption: [This aha moment] is what they need to experience

Phase B: Choose Validation Method (1-2 questions)

The validation method determines what you do next. Each tests different assumptions at different confidence levels.

Q1: Use AskUserQuestion: "How do you want to test these assumptions? Each method gives you a different type of signal."

Options:

• "Landing page" — "Put your value prop in front of real people. Measure signups, waitlist, or pre-orders. Tests whether your message resonates. Fastest to set up."
• "Conversations" — "Talk to 15-30 people who match your ICP. Validate the pain is real and acute. Deepest learning. Uses the Mom Test — no pitching, just listening."
• "Build & test" — "Build the MVP and put it in people's hands. Tests the aha moment directly. Highest effort, highest signal."
• "Not sure (needs research)" — "Add to open questions and help me decide."

If "Not sure (needs research)": Help them decide based on:

• How confident they are the pain exists → Low confidence = conversations first
• Whether they have access to ICP → Easy access = conversations; hard to reach = landing page
• Time/budget → Landing page is fastest; build is slowest but most definitive

Phase C: Define Success Criteria (2-3 questions)

Q2: Based on the chosen method, ask about the success metric:

If landing page: Use AskUserQuestion: "What action on the landing page counts as validation?" Options: "Email signup / waitlist" / "Pre-order / deposit" / "Free trial signup" / "Not sure (needs research)"

If conversations: Use AskUserQuestion: "What would you need to hear in conversations to feel confident the pain is real?" Options: "They've tried to solve it before (spent time/money)" / "They describe the pain unprompted" / "They ask when they can use the product" / "Not sure (needs research)"

If build & test: Use AskUserQuestion: "What user behavior would prove the aha moment is working?" Options: Pull from success criteria in

pmf/mvp.md

if it exists, plus "Not sure (needs research)"

Q3: "How many [signals] would be a strong enough signal?"

Provide guidance by method:

• Landing page signups: 50-100+ for consumer, 20-30+ for B2B
• Pre-orders: 10+ is strong for most products
• Conversations: 15-30 quality conversations
• Active users (build): 10-20 who return after first use

Define GO / ITERATE / PIVOT thresholds with the user.

Q4: "How long will you run this validation?"

Options:

• "1 week" — "Fast learning, smaller numbers. Good for landing pages with paid traffic."
• "2 weeks" — "Recommended for most. Enough time for organic reach and conversations."
• "4 weeks" — "Larger sample. Good for build & test or if you need time to set up outreach."
• "Not sure (needs research)" — adds timeline decision to Open Questions

# Validation Plan

<!-- AI_INSTRUCTION: This plan determines the next step in the PMF process.
     Check the Validation Method to know which execution skill to use. -->

## Assumptions Being Tested

1. **ICP:** [Identity] experiences "[pain]"
2. **Value Prop:** "[Message]" will make them say "that's me"
3. **MVP:** "[Aha moment]" is the experience that converts them

## Validation Method

**Method:** [Landing page / Conversations / Build & test]

## Success Metric

**Signal:** [What counts as validation]
**Goal:** [N] [metric] in [timeframe]

| Result | Threshold | Next Step |
|--------|-----------|-----------|
| **GO** | [X]+ | Invest in building / scaling |
| **ITERATE** | [Y]-[X] | Adjust message, channel, or approach and retry |
| **PIVOT** | <[Y] | Revisit ICP or value prop assumptions |

## Timeline

[X] weeks starting [date or "when ready"]

## What's Next

Based on your validation method:

- **Landing page** → Use the landing page generator to create your page
- **Conversations** → Use the outreach builder for your outreach plan + Mom Test questions
- **Build & test** → Use the build & test guide to set up BMAD with your PMF context

After saving, immediately ask:

Use AskUserQuestion: "Your validation plan is set. Ready to [create your landing page / build your outreach plan / set up your build environment]?"

Options: "Let's go" / "I'll do this later"

If "Let's go" — route to the appropriate skill:

• Landing page → landing-generator
• Conversations → outreach-builder
• Build & test → build-test-guide
