Build a Plan That Survives Contact With Reality
Most business plans are written once and forgotten. This one lives next to your data. Claude builds it with you, updates it as you learn, and — most importantly — stress-tests it before you bet your time and money on it. A plan that can't survive a hard question here was going to fail in the real world.
Before & After
You run a small landscaping company. You've been winging it for three years — things are okay, but you're not sure if you should hire, raise prices, or add a new service. You downloaded a business plan template once, filled in the first page, and never opened it again. When your accountant asks where you want the business in a year, you say "bigger" and hope that counts.
You're making decisions by gut feel, not data. Some of them are going to be expensive mistakes.
Same business. Claude interviews you for 30 minutes and produces a 3-page plan. Then you say "challenge my plan" and Claude finds the weak spots: your revenue projection assumes 4 new clients per month but your lead data shows 2. Your biggest client is 40% of revenue — if they leave, you can't make rent. Your hiring timeline assumes you'll have cash reserves you don't have yet.
Hard to hear. But now you fix it on paper instead of learning the hard way with real money.
What You Need
- Claude Desktop installed — follow the setup guide if you haven't yet
- 45 minutes — for the initial interview and plan creation
- Honesty — Claude can only plan around what you actually tell it. The more real your answers, the more useful the plan.
The Interview
Open Claude Desktop and tell it you want to build a business plan. Claude will interview you — one question at a time — about what your business does, who it serves, how money comes in, what it costs to operate, and where you want to be in 12 months.
The interview covers:
- What your business does (in plain English)
- Who your ideal customer is
- How customers find you today
- Your pricing model and typical revenue
- Your cost structure
- Your 12-month goal
- Your biggest risk
- What you've tried that didn't work
This takes about 30 minutes. Don't rush it. The quality of the plan depends on the quality of your answers. If you don't know a number, say so — an honest "I'm not sure" is more useful than a guess.
Claude Writes the Plan
Claude produces a business-plan.md file in your project folder.
Not a 50-page MBA document — a focused, 3-page plan in plain language
that covers:
Business Overview
What you do, who you serve, how you deliver value
Target Customer
Who they are, how they find you, what they care about
Revenue & Costs
How you make money, what it costs, what the margins look like
Growth Strategy
How you get from here to your 12-month goal
Risks & Assumptions
Every assumption the plan depends on, stated explicitly
Key Metrics
3–5 numbers that tell you if the plan is working
The plan is a file on your computer. You can open it in any text editor, print it, share it with a partner or advisor. It's not trapped in a chat window.
Set Up the Update Skill
A business plan that never changes is a business plan that's wrong. Tell Claude:
Update when something meaningful changes: a new service, a price increase, a lost client, a new marketing channel. Monthly at minimum. The changelog lets you look back and see how your thinking evolved.
Set Up the Suggestions Skill
This is where the plan gets smarter over time. If you've been using other Tsidai workflows (invoicing, email triage, market research, month-end), Claude has been learning about your business from real data. Tell Claude:
Claude doesn't guess — it draws from real data. If the plan says "target 10 new clients per month" but your lead capture shows 3, Claude will flag it. If your month-end reports show margins shrinking, Claude will suggest revisiting the pricing section.
Set Up the Stress Test
This is the most important step. A business plan that can't survive hard questions here is going to fail when real money is on the line.
Tell Claude:
"Save a skill called 'stress-test'. When I say 'challenge my plan', read business-plan.md and try to break it. Your job is to find the weakest parts and prove they will fail. Be specific. Use real numbers from my sheet and bank data if you have them. Don't hedge or soften. I need the hard truth now, not six months from now."
Claude will:
Your Four Planning Skills
Once everything is set up, your business plan is a conversation away:
"Update my plan"
Something changed? Claude asks what, updates the doc, and logs the change.
"What should I change?"
Claude suggests improvements based on real data from your other workflows.
"Challenge my plan"
Claude stress-tests every assumption and finds where the plan breaks.
The plan itself
A real file on your computer. Open it anytime. Share it with anyone.
What You've Built
- A living business plan that updates as your business evolves
- A suggestion engine that draws from real operational data, not theory
- A stress test that finds failure modes before you invest real money
- A changelog that shows how your thinking has evolved over time
- A document you can hand to an accountant, a partner, a lender, or an advisor
Most small business owners don't plan because plans feel theoretical and disconnected from daily reality. This one isn't. It's built from your real numbers, updated by your real experience, and challenged before you bet on it.

Skill: Business Planner - Build a Plan That Survives Contact With Reality
What this is for: Walk a small business owner through building a living business plan with Claude — then set up four skills: (1) build the initial plan through an interview, (2) update the plan as the business evolves, (3) suggest improvements based on what Claude has learned working with the owner, and (4) stress-test the plan by finding where it fails. The plan lives as a file Claude can read and write to — not trapped in chat history.
