SYSTEM DOCUMENTATION & REQUIREMENTS

πŸ’‘ This Skill includes references (resource) components.

What problem does it solve? Independent developers often build products based on compliments and hypotheticals instead of real demand. This Skill coaches founders through 5-15 Mom Test-style customer interviews, turning conversations into traceable evidence about pain, spending, and switching behavior before any large build. ## Core Features & Use Cases - Interview Setup: Generates ICP definitions, falsifiable G1/G2/G3 hypotheses, recruit scripts, and a past-behavior-first interview guide, scaffolded under docs/discovery/. - Structured Debriefs: Writes per-interview notes with verbatim quotes, Mom Test violation audits, and gate deltas so evidence stays traceable. - Synthesis & Decision: Clusters patterns across interviews, scores the Pain/Spend/Switch gates, and produces an explicit Advance / Reshape / Park verdict with a fixed Evidence handoff table. - Use Case: A solo founder with a SaaS idea uses the skill to recruit 10 target users, debrief each call, and discover that only one segment actually pays for workarounds β€” reshaping the product wedge before writing code. ## Quick Start Ask the agent to set up a customer discovery plan for your product idea, including an interview guide and recruit scripts for your target users.

Frequently Asked Questions about z-customer-discovery

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run customer discovery interviews for a startup idea?β–Ό

Recruit 5-15 people matching a narrow ICP, ask about the last time they hit the problem rather than pitching your idea, and debrief each call into structured notes. The skill generates the interview guide, recruit scripts, and synthesis templates for this process.

What is the Mom Test method for user interviews?β–Ό

The Mom Test means asking about past behavior instead of future intentions: talk about their life not your idea, ask about the past not the future, and listen more than you talk. Compliments and hypothetical interest are treated as weak evidence.

How many customer interviews do I need before building a product?β–Ό

The skill targets 5-15 completed interviews, with a minimum of 5 before making strong claims and up to 15 for B2B or high-variance markets. At least half should be cold contacts rather than friends or family.

Can AI simulate customer interviews instead of talking to real users?β–Ό

No. The skill explicitly refuses to role-play fake customers or generate persona interviews as evidence, since fabricated conversations cannot validate real demand. It only helps plan, debrief, and synthesize interviews with actual people.

When should I use landing page smoke tests instead of customer interviews?β–Ό

Use a landing page smoke test when you need behavioral conversion data at scale rather than deep qualitative understanding. Interviews explain why people act; smoke tests measure whether they act, and the two approaches complement each other.
