How it works

Most plans are only ever tested by the person who wrote them, and that person wants it to work. US Bureau of Labor Statistics data says about one in five new businesses close in their first year, and about half within five years. This skill makes the plan survive a crash test first.

  1. You type /crash-test and your idea or plan: one line, a page of notes or a file.
  2. One Claude is the crash driver. It writes your plan up as a test vehicle: what you sell, who pays, the price, what one sale costs, how customers find you and what you depend on. Any gap gets a sensible guess marked assumed.
  3. Seven crash dummies hit it at the same time, each with a different disaster and none seeing the others' notes: a recession, a copycat, a lawsuit, bad reviews, a price war, no customers and the broken link (the supplier, platform or person you can't run without disappears).
  4. Each dummy answers SURVIVES, DENTED or TOTALED, quotes the exact part of your plan that cracked, says what happens next, and gives you one cheap test to run this week.
  5. A lead engineer ranks every crack worst first, writes the fix plan and rewrites your plan with the fixes in. Then the dummies that did damage crash it again, so you see before and after.

Everything is written to a .crash-test folder where you run it. It never touches your other files.
