You are a Series B startup CFO who has raised $40M and managed a burn rate through two recessions. I'm a first-time founder. Review my 18-month financial model and tell me the three assumptions most likely to kill this company: [paste model]

Example 1 — Problem Solving

Think step by step. A SaaS company has 5,000 users, a 3% monthly churn rate, and is adding 200 new users per month. At what month does user growth stall completely? Show your full calculation.

Example 2 — Business Decision

Example 1 — Tone Matching

Here are three subject lines I've written for my email newsletter. Each should feel punchy, specific, and never clickbait:
1. "The AI tool that replaced my entire research team"
2. "Why I stopped using GPT-4 for first drafts"
3. "$0 AI stack that does what a $500/month tool used to"

Example 2 — Customer Persona

You are a 52-year-old restaurant owner in a mid-size US city. You are not technical, have no interest in learning new software, and are skeptical of any tool that costs more than $50/month. I am going to pitch you my AI reservation system. Tell me your honest reaction, objections, and what would actually change your mind.

Example 1 — Writing Constraints

Example 2 — Decision Clarification

I'm trying to decide whether to pivot my startup. Instead of giving me advice, ask me 8 questions that will help me think through this decision clearly. Ask one at a time. Wait for my answer before asking the next.

Example 1 — Tool Comparison

- Always end with: "Is there anything else I can help with today?"

Example 2 — Personal Writing Assistant

You are my personal writing assistant. My writing style: direct, data-driven, no fluff, conversational but professional. Audience for everything I write: technical founders. Default output: 80% of my requested length. Always push back if I ask for something that will sound generic. Never start a draft with a question.

Example 1 — Codebase Analysis

I'm pasting our entire backend codebase below (approximately 80,000 tokens). Read through it and answer: (1) What are the top 3 architectural patterns in use? (2) Where is the most technical debt concentrated? (3) Which module would be most risky to refactor first? [paste codebase]

Example 2 — Document Cross-Reference

I'm pasting 6 months of customer support tickets and our product changelog.

[paste documents]

Example 1 — Writing Self-Critique

Turn 1: Write a 200-word product description for [product]. [Claude produces draft] Turn 2: Now critique what you just wrote. What are the 3 weakest parts? Where is it generic? Where does it fail to differentiate the product? Then rewrite it fixing all three issues.

Example 2 — Strategy Self-Critique

Turn 1: Give me a 90-day marketing plan for launching a new developer tool. [Claude produces plan] Turn 2: Review the plan you just created. What assumptions does it make that might be wrong? What did it leave out? What would a skeptical CMO say about it? Then revise the plan addressing those gaps.

Example 1 — Research Agent

Your goal: produce a competitive analysis report on the top 5 AI writing tools as of April 2026. Steps you should take: (1) identify the top 5 tools by search volume and user reviews, (2) analyze each tool's pricing, core features, and target user, (3) identify one unique strength and one major weakness per tool, (4) produce a final recommendation for a 10-person content team with a $500/month budget. Work through each step. Show your reasoning between steps.

Example 2 — Project Planning Agent

Goal: create a complete launch plan for a mobile app. I will tell you the constraints and you will figure out the steps. Constraints: 2 developers, 3-month timeline, $30,000 marketing budget, targeting iOS first. Produce: (1) a week-by-week development timeline, (2) a pre-launch marketing plan, (3) a day-1 launch checklist, (4) a 30-day post-launch success metric framework. Reason through dependencies before writing each section.
