What you unlock

A Claude Code skill that applies the Feynman Technique to any concept. You explain first — Claude identifies your gaps, probes them one at a time, then delivers a calibrated explanation (surface → mechanism → implication → analogy) tuned to your expertise level. First run asks three questions about your background and interests, then writes them back into the skill file so every future analogy draws from your world. Also generates structured HTML concept explainers for dashboards, reports, and client presentations.

OutcomeBuilt at LeadGrow, used in live pipelines, shipped open source so you don't have to build it yourself.
See it in action

3 things you can do right now.

No UI. No clicking. Just commands that execute.

Trigger interactive mode on a concept
$ feynman pipeline velocity
What's your current relationship with pipeline velocity? Heard of it / worked with it / built systems around it?
OutcomeClaude calibrates depth before explaining. You get the version that actually moves you forward.
Hold the line — you explain first
$ > "It's like... how fast deals move through the funnel?"
Close. You've got the direction right but missed the denominator. One gap: what does "velocity" divide by — time, stage, or something else?
OutcomeFeynman requires you go first. Claude finds the exact gap and probes it once before correcting.
Generate an HTML concept explainer
$ feynman CAC payback period --html # Audience: practitioner | Context: investor update deck
<div class="feynman-concept" ...> <h3>CAC Payback Period</h3> <p>How long until a customer pays back what it cost to acquire them.</p> ...
OutcomeDrop a calibrated explainer into any report or dashboard. No copy-paste from Wikipedia.
What's included

Every capability, ready to script.

Interactive mode — you explain first, Claude probes gaps, then delivers the full picture
Expertise calibration — heard of it / worked with it / built systems around it changes the explanation depth
Self-modifying user profile — first run captures your background and writes analogy domains back into the skill file
Analogy targeting — uses your specific domains (sport, industry, hobby) so concepts land in your world
Dashboard mode — outputs styled HTML concept explainers for reports and presentations
In-scope concept guard — won't run Feynman on opinion topics; offers frameworks instead
The workflow

End to end. Zero manual steps.

The analogy section adapts to whoever installed it. A sales operator gets pipeline metaphors. A developer gets component metaphors. The concept is the same. The landing is personal.

01

Install the skill.

Three curl commands copy the skill into your workspace. Claude Code picks it up automatically — no restart, no config.

$ mkdir -p .claude/skills/feynman/references curl -sL .../SKILL.md -o .claude/skills/feynman/SKILL.md
02

First run: set your profile.

Claude asks three questions — your role, outside interests, and one domain you know cold. Answers get written back into the skill file. Every analogy from that point forward is yours.

$ feynman gradient descent # → "What do you do? What are you into outside work? What do you know cold?"
03

Explain the concept yourself.

Feynman requires you go first. Claude holds the line — asks you to attempt an explanation before it touches the concept. That friction is the mechanism.

$ > "It's like... tuning a dial until the output improves?"
04

Gaps probed. Full picture delivered.

Claude identifies 2–3 gaps from your explanation, probes the most foundational one first, then delivers surface → mechanism → implication → analogy in your language.

$ # Analogy drawn from your profile: # Powerlifting operator → "Progressive overload, but for loss functions."
Real scenarios

What teams actually use it for.

Not theoretical. These are the pipelines running at LeadGrow and client stacks today.

01Learning a technical or business concept before applying it — not just memorizing a definition
02Pressure-testing your understanding of something you think you know
03Generating concept explainer blocks for client decks, dashboards, or onboarding docs
04Building a shared vocabulary across a team on fast-moving topics (AI, infra, GTM strategy)
Included skills

Pre-built automations. Ready to run.

These aren't demos. They're the Claude Code skills we run inside LeadGrow, shipped open source so you don't have to build them yourself.

feynman-interactive

Interactive Feynman

The core technique. You explain first. Claude probes your gaps one at a time. Then delivers surface → mechanism → implication → analogy calibrated to your level and background.

Triggers: "feynman [concept]" / "teach me [concept]" / "help me understand [concept]"
feynman-html

Concept Explainer (HTML)

Generates a structured HTML block with four-part breakdown — definition, mechanism, implication, analogy. Audience-calibrated. Drop it into any report, dashboard, or deck.

Triggers: "feynman [concept] --html" or "explain [concept] for dashboard/report"
feynman-profile

Profile Setup

Runs once on first invocation. Three questions about your role, interests, and strongest domain. Writes the answers back into SKILL.md so analogies stay personal across every session.

Triggers: Automatic on first use — or "update my feynman profile" to reset
