01
Expose and rank the hidden assumptions
Run the plan, constraints, and evidence through a structured challenge that separates facts from unproven claims and turns critical uncertainty into fast checks.

Make Your Play
Give us the situation. We’ll build the prompt.
Catch hidden dependencies, unsupported expectations, and uncertain system behavior before they turn into delays, incidents, or expensive rework.
Your answers save as you type.
What you'll do
This is the plan inside your prompt. Add your details first. Then follow these steps with ChatGPT or Claude.

Find the Assumptions Hiding in a Technical Plan
Tell us what the prompt needs to know
Start with the questions below. Each answer personalizes the playbook and builds the prompt you’ll use at the end.
Your situation
Paste the proposed implementation, design, migration, integration, or rollout plan.
0/10000
List the known requirements, deadlines, limits, dependencies, and conditions the plan must satisfy.
0/10000
List the measurements, tests, documentation, production observations, or confirmed commitments that support the plan.

Assembled prompt
Beginner instructions
Paste the plan as written, even if it is incomplete. Include known constraints and any evidence already collected. If no evidence exists, enter “None yet.”
Advanced instructions
Include design records, interface contracts, production metrics, incident history, rollout controls, and dependency commitments when available. Challenge correlated assumptions and checks that rely on the same unverified source.
Use this when
You're reviewing an implementation plan, design proposal, migration approach, integration plan, or major code change before work begins.
You'll need
- Technical plan
- Requirements and constraints
- Available evidence
You'll get
- Every material assumption stated in testable terms
- Critical assumptions ranked with evidence gaps visible
- A fast validation check and pass/fail signal for every top risk
- A proceed, check, or pause recommendation supported by the analysis
- Fallback changes identified for the three highest-priority assumptions.
By the end of this playbook

- Critical assumptions ranked with evidence gaps visible
- A fast validation check and pass/fail signal for every top risk
- A proceed, check, or pause recommendation supported by the analysis
- Fallback changes identified for the three highest-priority assumptions.
