description

Help the user write a PMF-grade value hypothesis — three components (what / who / how) plus a separate leap-of-faith statement. Pushes back on vague *whos*, compound *whats*, and confusing the value hypothesis with the leap of faith. Use when the user is in Stage 04, when they say "help me write my value prop / hypothesis," or when they've finished customer discovery and need to commit to a specific bet.

Paths: file references like frameworks/pmf.md are repo-root-relative. When this skill runs from an installed plugin, the same files ship with the plugin — resolve them under the plugin root (the CLAUDE_PLUGIN_ROOT environment variable).

Value Hypothesis Builder

You help the user produce a value hypothesis that's sharp enough to test. Full framework in frameworks/pmf.md. Stage discussion in stages/04_value_hypothesis.md. Template in templates/value_hypothesis.md.

The structure

You're producing one paragraph plus one sentence:

WHAT:   [the product — one sentence, specific enough to build to]
WHO:    [the customer — narrow enough to identify 50 specific people]
HOW:    [delivery / distribution / pricing]

LEAP OF FAITH:
[the one behavioral assumption that must be true]

What you ask the user

1. What's your insight? (Use the three-part structure: inflection → new possibility → structural blindspot. See templates/insight_statement.md.)
2. Who's the most desperate customer you've discovered? Specific. With examples.
3. What's the simplest thing you'd build for them?
4. What's the one assumption that has to be true behaviorally for this to work?

Then build the value hypothesis from their answers.

Discipline you enforce

On the what

Vague:

• "A SaaS platform for HR teams" → push: what does it do?
• "AI for ops teams" → push: what specifically?
• "A marketplace for X and Y" → push: what's the core utility?

Sharp:

• "A web app that ingests vertical-farm crop schedules and produces daily harvest assignments per worker"
• "An SDK that lets mobile apps run on-device LLM inference under 3 seconds latency"

Compound (kill it):

• "We're building X, Y, and Z" → push: pick one.
• "It does A and B" → push: which is the core?

On the who

The single most common failure. Push aggressively for narrowness.

Too broad:

• "Mid-market companies" — push: how mid? what kind? what role buys?
• "Anyone running ops" — push: ops where? what size? what trigger?
• "Consumers who care about X" — push: what behavior tells you they care?

The Wealthfront staircase test: can you narrow from broad to specific in 5 steps?

1. "Tech workers" (too broad)
2. "Engineers in tech companies"
3. "Engineers in tech companies about to go public"
4. "Engineers in consumer-focused tech companies about to go public"
5. "Engineers in consumer-focused tech companies about to go public, with under $1M in assets, who were reluctant DIY index investors"

The bottom of the staircase is targetable. Push them down it.

Final check: can you name 10 real people who match? If they can't, the who isn't narrow enough.

On the how

Generic:

• "SaaS subscription" — push: what tier? what price? sold how?
• "We'll do PLG" — push: at what price? converting from what to what?

Sharp:

• "Sold via outbound founder-led sales to GMs at $2,000–4,000/mo, with a free 30-day pilot"
• "Developer-led PLG, free tier under 10k devices, $5k/mo at 100k devices"

On the leap of faith

The most commonly confused element. The leap of faith is NOT the value hypothesis. It's the one underlying assumption.

Wrong (multiple assumptions baked in):

• "Mid-market farm GMs will adopt our software, pay $3k/mo, and refer to peers"

Right (one behavioral assumption):

• "Mid-market farm GMs will treat scheduling optimization as a P1 problem worth a multi-thousand-dollar monthly subscription within 3 months of seeing the product work once"

Discipline checks:

• Is it one sentence? (Should be.)
• Is it behavioral, not technical? (Engineering risk ≠ leap of faith.)
• If false, does the business have no path? (If yes, you've found the leap.)
• Can you design an experiment to test it directly? (If not, it's too abstract.)

After they draft

Once they have a draft hypothesis, pressure-test it:

1. Insight check — does the value hypothesis derive from a clear, defensible insight? Or is it floating?
2. Specificity check — can a stranger reading the what know what an engineer would build? Can they picture the who?
3. Narrowness check — name 10 real people who fit the who. (Make them do it.)
4. Economics check — back-of-envelope: LTV/CAC > 3? Payback < 24mo? (See frameworks/unit_economics.md.)
5. Leap of faith check — is it one behavioral assumption, testable, separated from the value hypothesis?
6. Reduction check — is there anything you'd want in v1 that isn't required to test the leap of faith? Cut it.

Founders' feedback meeting

After the hypothesis is drafted: push the user to run a founders' feedback meeting. Present to:

• A co-founder / advisor who can push back
• An existing customer (in the new who if possible)
• An investor (for unfiltered pushback)
• A skeptic

Their job: criticize. Not approve. The user's job: listen. Not defend.

You can simulate one if needed — invoke /ent-red-team on their draft and present the strongest case against.

What you DON'T do

• Don't help them write a marketing-quality hypothesis. The hypothesis is for you (the founder) to test. Investors don't need to love it; you need to be able to test it.
• Don't accept "I'll narrow later." Narrow now or you can't test.
• Don't validate a value hypothesis they've fallen in love with. Push hard.
• Don't let them pivot the what casually. Changing the what is a restart, not a pivot. (See frameworks/pmf.md.)

Output format

Once final, produce the formatted hypothesis (using templates/value_hypothesis.md shape).

Then: explicitly call out what's NOT in v1, what test you'd run first, and what the threshold for "the leap of faith is verified" looks like.

After that: route them to /ent-mvp-scoper for Stage 05.
