What its author says it does

Copied from the file, not written here

Orchestrates behavior-led idea and market validation—problem interviews, pretotype experiments, paid traffic, demand proxies, competitor revenue estimates, and unit economics—before build. Use when validating a business idea end-to-end, testing willingness to pay, or planning experiments before build.

Behavior-Led Validation

Orchestrator skill. For depth on one step, invoke the child skill listed below. For stage gates and artifact order, start with discovery-playbook.

Principle

Validate with observed behavior and payment, not opinions. Strongest signal: customers pay at the target price before software exists.

Validation order: idea validation → market validation → product validation (after a prototype). Landing pages, ad tests, and concierge delivery are not product validation.

Workspace rules

No-build boundary: no production app scaffold until idea-scorecard records Strong go or Conditional go.
Read discovery/INDEX.md and only discovery/<topic-slug>/ before extending work. Create discovery/INDEX.md if missing.
Do not open discovery/archive/ unless the user explicitly asks.

Phase map

Phase	Goal	Primary skills
Idea	Problem is real and painful	`assumption-map`, `problem-discovery`, `regulatory-risk-scan` (if regulated), `feasibility-gate`
Market	Demand, wedge, economics	`market-research`, `competitor-landscape`, `market-sizing`, `positioning-wedge`, `revenue-model`
Demand test	Falsify riskiest assumptions	`validation-experiments`
Decision	Go / conditional / pivot / kill	`idea-scorecard`, `discovery-synthesis`
Product (post-prototype)	Solution fit	`pmf-sean-ellis`

Phase 1 — Idea and market demand (summary)

Problem interviews — follow problem-discovery (15–20 ICP, Mom Test ladder, commitments). Optional switching depth → jtbd-interviews.
Willingness to pay — priced landing + Stripe or equivalent; thresholds in validation-experiments. Not validated: email-only waitlist.
Paid traffic — ~$100–$500; track CTR and conversion; compute ILI when applicable (see validation-experiments).
Desk demand — keywords and forums as research priority proxies only; pair with payment or interviews.

Save under discovery/<topic-slug>/briefs/, research/, or experiments/.

Phase 2 — Revenue and costs (summary)

Competitor revenue: headcount heuristic, mobile estimates, aggregators — label all as assumptions.
Unit economics: LTV:CAC ≥ 3:1 for strong go; < 2:1 kill — see revenue-model bands.
Reference metric bands (directional, verify for segment): seed MRR narratives, B2B retention, NPS — not pass/fail without context.

Full scenarios → revenue-model.

Evidence mapping

Use the canonical hierarchy in idea-scorecard (levels 1–5). Quick reference:

Label	Maps to level
L0–L1 views, likes, compliments	1–2
L2 waitlist / signup	3
L3 repeat use, design-partner time	4
L4 deposit, LOI, pilot	5
L5 recurring payment at target price	5

Strong go still requires the weighted scorecard bar in idea-scorecard.

Strongest path

When feasible: concierge MVP for a small paid cohort, then automate. Sequence with fake door → concierge per validation-experiments.

Regulated ideas

If health, fintech, legal, or similar constraints apply → regulatory-risk-scan before scaling tests.
