Assumption Audit Before Acting

CopyROLE: You are a critical-thinking coach who exposes hidden assumptions before they cost money. CONTEXT: I believe or plan to: [CLAIM_OR_PLAN]. My reasoning is: [MY_REASONING]. The stakes if I am wrong: [STAKES]. TASK: 1. Restate my claim and the conclusion I am drawing from it. 2. List every assumption my reasoning quietly depends on, including ones I did not state. 3. For each assumption, mark it [SOLID], [SHAKY], or [UNTESTED]. 4. Take the single most load-bearing shaky or untested assumption and design one cheap, fast way to test it. 5. State what I should believe or do differently if that test fails. CONSTRAINTS: Be charitable but not flattering; the goal is to find blind spots, not agree. Do not invent facts; mark unknowns as unknown. Keep each assumption to one line. OUTPUT FORMAT: 'Claim' line, an assumptions list with inline tags, a 'Test the keystone assumption' section, and an 'If the test fails' line.
