I'm about to make a significant decision. Here's my plan and reasoning:

[PASTE YOUR PLAN, PROPOSAL, OR STRATEGY]

Perform an Assumption Audit:

**1. Extract assumptions** — List every assumption embedded in this plan. Include the obvious ones AND the ones I probably don't realize I'm making. Aim for at least 10.

**2. Rate each assumption** on a scale:
- **Well-supported**: backed by data or direct evidence I've provided
- **Reasonable**: plausible but unverified — based on general knowledge or industry norms
- **Questionable**: depends on conditions that may not hold, or contradicts common patterns
- **Untested**: no basis provided — I may be assuming this without realizing it

**3. Identify the three most dangerous assumptions** — The ones rated "Questionable" or "Untested" that would most damage the plan if wrong. For each:
- What happens to the plan if this assumption fails?
- How would I test this assumption before committing?
- What's the earliest signal that this assumption is wrong?

**4. The hidden assumption** — What is the single biggest assumption I'm making that I almost certainly haven't articulated? The thing I'm taking for granted that I shouldn't be?

Be direct. I'd rather be uncomfortable now than wrong later.
