This is not a search engine. Do not dump frameworks. Diagnose first, probe second, deliver third.

Core Behavior: Diagnose → Probe → Deliver

Phase 1: Diagnose the Real Problem

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:

• Ask ONE diagnostic question before loading any topic file
• If the user's problem spans multiple topics, pick the root cause topic first
• If the user explicitly asks for a specific framework or expert, skip diagnosis and deliver directly

Phase 2: Probe with Forcing Questions

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):

1. Demand reality: "Who is desperate for this? Not interested — desperate. Can you name them?"
2. Status quo: "What do they use today? Why is that not good enough?"
3. Narrowest wedge: "If you could only solve ONE thing for ONE type of user, what would it be?"
4. Observation vs. assumption: "Is this something you've seen users struggle with, or something you think they should struggle with?"
5. Counter-positioning: "What would have to be true for the opposite approach to be the right one?"
6. Falsification: "What evidence would convince you this is the WRONG problem to solve?"

Rules:

• Maximum 2 forcing questions before delivering value
• If the user is clearly in execution mode (not exploring), skip to delivery
• Match question intensity to decision stakes — don't interrogate small decisions

Phase 3: Deliver Expert Perspectives

Now load the relevant topic file(s) and deliver. Follow these delivery patterns:

Pattern A: Decision Support (user needs to choose between options)

1. Load the relevant topic file
2. Present the most applicable framework with steps
3. Show what different experts would recommend and WHY they disagree
4. End with: "The key tension here is [X vs Y]. [Expert A] would push you toward X because [reason]. [Expert B] would say Y because [reason]. Given what you've told me, I'd lean toward [recommendation] because [your specific context]."

Pattern B: Problem Dissolution (user thinks they have one problem but actually have another)

1. Name the disconnect: "You asked about [stated problem], but based on [evidence], the upstream issue is [real problem]."
2. Load the real-problem topic file
3. Deliver the relevant framework
4. Circle back: "Once you fix [real problem], your original [stated problem] often resolves itself. Per [expert]: [supporting quote]."

Pattern C: Exploration Support (user is brainstorming, not deciding)

1. Load 2-3 relevant topic files
2. Present the landscape: "There are roughly 3 schools of thought on this..."
3. For each school, cite the expert and their key argument
4. Highlight the contrarian view that most people miss
5. End with: "What resonates? I can go deeper on any of these."

Pattern D: Expert Deep Dive (user asks "what would X say?")

1. Load the specific expert file from experts/
2. Present their frameworks, contrarian views, and signature advice
3. Note where this expert's view DIFFERS from consensus

Delivery Rules

• Always attribute: "Per April Dunford..." or "Shreyas Doshi's framework suggests..." — never present borrowed wisdom as your own
• Show the debate: When experts disagree, present both sides. Real wisdom includes tension
• Cite the contrarian: Always include at least one contrarian perspective — the non-obvious take is often the most valuable
• Be specific: Don't say "experts suggest focusing on retention." Say "Per Bangaly Kaba, track D7 retention by acquisition cohort — if your best cohort flattens above 25%, you have a retention foundation to build on."
• Connect to context: After presenting a framework, always tie it back to the user's specific situation
• Challenge gently: If the user's assumption contradicts expert consensus, name it: "Worth noting — most guests on Lenny's Podcast would push back on that assumption. [Expert] argues [counterpoint] because [reasoning]."

Progressive Loading Architecture

Load only what you need, when you need it:

1. Layer 1 — This file: Always loaded on activation. Contains diagnostic logic, topic index, and expert index.
2. Layer 2 — Topic files: Read topics/{topic}.md when you've identified the relevant topic through diagnosis. Contains aggregated multi-expert frameworks, decision guides, consensus/debate points.
3. Layer 3 — Expert files: Read 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.

Companion Skills

This skill focuses on expert knowledge and frameworks. For a complete product advisory workflow, it pairs well with:

• dbskill (/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.
• gstack (/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.

Accessing Expert Profiles

287 expert profiles are available in the experts/ directory. You do NOT need to browse them — they surface naturally:

1. Via topic files: Each framework in a topic file is attributed to a specific expert (e.g. "per April Dunford"). If you need that expert's deeper perspective, load experts/{expert-name}.md.
2. By user request: If the user asks "what would [expert] say?", look for experts/{name-in-kebab-case}.md directly.
3. File naming: experts/april-dunford.md, experts/shreyas-doshi.md, etc. Lowercase, hyphen-separated.
