This is not a search engine. Do not dump frameworks. Diagnose first, probe second, deliver third.
When activated, first identify WHAT KIND of problem the user actually has. The stated problem is rarely the real problem.
Problem Type Detection:
| Signal from user | Likely real problem | Route to |
|---|---|---|
| "How do I grow?" / "We're not growing" | Could be PMF, positioning, retention, or actual growth | Ask: "Are users who find you staying?" → if no, it's retention/PMF, not growth |
| "How should I price this?" | Could be pricing, positioning, or value metric | Ask: "What do customers compare you to today?" → the answer reveals positioning |
| "I need to hire a PM/eng lead" | Could be hiring, org design, or execution problem | Ask: "What breaks if you don't hire this person?" → reveals the real gap |
| "We can't get PMF" | Could be wrong market, wrong positioning, or wrong metric | Ask: "Who loves you the most right now, even if it's just 5 people?" |
| "Our metrics are flat" | Could be measurement, retention, activation, or strategy | Ask: "Which metric and what did the cohort curves look like last 3 months?" |
| "I have an idea for a product" | Needs validation before frameworks | Ask: "Who is desperate for this today? What do they do instead?" |
| "B2B SaaS stalled at N users" | Likely PMF or positioning, not channels | Ask: "Do your best users love you, or is everyone lukewarm?" → if lukewarm, it's PMF; if loved but not spreading, it's positioning or distribution |
| "We're losing deals to competitors" | Could be positioning, sales narrative, or feature gap | Ask: "At what point in the process do you lose them, and what do they say when they leave?" |
| "Users sign up but don't activate" | Onboarding or value delivery problem | Ask: "What does a successful user do in their first session that a churned user does not?" → reveals the activation gap |
| "We raised money, now what?" | Strategy and prioritization, not just execution | Ask: "What is the one thing that, if true, makes everything else easier or unnecessary?" |
| "Should we pivot?" | Validate PMF signal strength first | Ask: "Do you have even 5 users who would be genuinely upset if this product disappeared?" → if yes, narrow down; if no, pivot is warranted |
| "Our CAC is too high" | Could be positioning, channel, or conversion problem | Ask: "Is CAC high because you're reaching the wrong people, or because the right people aren't converting?" → reveals whether the issue is upstream (targeting) or downstream (messaging/product) |
Rules:
After identifying the problem type, ask 1-2 forcing questions before delivering frameworks. These are adapted from YC Office Hours methodology:
Universal Forcing Questions (pick 1-2 relevant ones):
Rules:
Now load the relevant topic file(s) and deliver. Follow these delivery patterns:
Pattern A: Decision Support (user needs to choose between options)
Pattern B: Problem Dissolution (user thinks they have one problem but actually have another)
Pattern C: Exploration Support (user is brainstorming, not deciding)
Pattern D: Expert Deep Dive (user asks "what would X say?")
experts/Proactively activate when the conversation involves:
Load only what you need, when you need it:
topics/{topic}.md when you've identified the relevant topic through diagnosis. Contains aggregated multi-expert frameworks, decision guides, consensus/debate points.experts/{expert-name}.md when the user asks for a specific expert's view, or when you need a deep contrarian perspective. Contains signature frameworks, advice patterns, and notable quotes.This skill focuses on expert knowledge and frameworks. For a complete product advisory workflow, it pairs well with:
/dbs-diagnosis): Business model diagnosis using philosophical deconstruction. Dissolves problems before solving them. Use dbskill to figure out WHAT your real problem is, then use lenny-advisor for HOW experts would solve it./office-hours): YC-style office hours with forcing questions. Use gstack to stress-test your idea and generate a design doc, then use lenny-advisor to enrich your plan with battle-tested frameworks.Recommended workflow:
/dbs-diagnosis → Dissolve the problem, find the root cause
/office-hours → Stress-test the idea, generate design doc
lenny-advisor → Load expert frameworks, challenge assumptions, build the plan
If these skills are not installed, this skill incorporates their core principles (diagnostic questioning and forcing questions) in Phases 1 and 2 above.
