Mom Test — Customer Discovery Plugin for Claude Code
A Claude Code plugin that turns Rob Fitzpatrick's The Mom Test into an operating layer for customer discovery — preparing for calls, auditing interview questions, drafting outreach, framing meetings, taking call notes, reviewing evidence, segmenting customers, and choosing the right commitment ask.
Ships as a plugin marketplace with one plugin (mom-test) containing 14 slash commands and a routing skill that catches natural-language requests too.
Install
From GitHub (recommended)
In Claude Code:
/plugin marketplace add github:glennmatlin/mom-test
/plugin install mom-test@mom-test-marketplace
Restart your Claude Code session (or run /reload-plugins). Type /mom-test: and all 14 commands should appear in the picker.
From a local clone
If you've cloned the repo locally:
/plugin marketplace add /absolute/path/to/mom-test-skill-package
/plugin install mom-test@mom-test-marketplace
What you get
14 slash commands (full list in mom-test/commands/):
| Command | What it does |
|---|
/mom-test:prep | Prepare a batch of discovery conversations |
/mom-test:audit-questions | Rewrite interview questions to pass the method |
/mom-test:generate-questions | Generate a question bank for a customer type |
/mom-test:write-outreach | Draft outreach for a discovery conversation |
/mom-test:frame-meeting | Draft a meeting opener + first questions |
/mom-test:live-note | Turn raw call notes into a structured note |
/mom-test:review-notes | Synthesize a batch of notes into evidence + next questions |
/mom-test:commitment-ask | Pick the right post-meeting commitment ask |
/mom-test:segment-slice | Tighten a broad segment into who-where pairs |
/mom-test:find-conversations | Sourcing plan for reaching a segment |
/mom-test:diagnose-pipeline | Audit whether discovery is producing learning |
/mom-test:follow-up-email | Draft a follow-up that advances the relationship |
/mom-test:evidence-memo | Decision-grade evidence summary |
/mom-test:product-risk | Decide whether more conversations help or product risk dominates |
Plus a routing skill. Even without typing a slash command, saying things like "help me prep for some customer calls" or "can you rewrite these interview questions?" will trigger the right workflow. Useful for users who don't want to memorize command names.
Plus reference notes and reusable templates in mom-test/resources/ and mom-test/templates/ for deeper background and consistent output formats.
