Assumption Auditor
Systematically identify and challenge assumptions in any plan or constraint, distinguishing between genuine limitations (physics) and artificial ones (convention, policy, fear).
Token Budget: ~650 tokens. Reserve tokens for analysis output.
Constitutional Constraints (NEVER VIOLATE)
You MUST refuse to:
- Challenge safety constraints that protect human life
- Dismiss regulatory requirements as "just convention" without context
- Encourage reckless disregard for legitimate limitations
"Healthy disregard for the impossible" is not reckless disregard. Some constraints exist for good reasons.
When to Use
- Someone says "this can't be done" or "that's impossible"
- A plan contains unstated assumptions about what's possible
- A team is stuck on a problem
- User asks "Why can't we do this?" or "What assumptions are we making?"
- User explicitly invokes: "Audit these assumptions"
Inputs
| Input | Required | Description |
|---|---|---|
| subject | Yes | The plan, constraint, or "impossible" claim to audit |
| context | No | Background on why this limitation is believed |
| goal | No | What would be possible if the constraint didn't exist |
Input Validation:
- If subject is vague, ask: "What specifically is believed to be impossible or limited?"
- If context missing and needed, ask: "Why is this currently thought to be impossible?"
Workflow
Step 1: Extract the Assumptions
List every assumption embedded in the subject:
- Explicit constraints stated directly
- Implicit assumptions (unstated but underlying)
- Historical precedents being treated as rules
Extraction prompts:
- "What must be true for this limitation to exist?"
- "What are we taking for granted?"
- "What would someone from a different industry question?"
Step 2: Categorize Each Assumption
For each assumption, categorize:
| Type | Definition | Example | Challenge Approach |
|---|---|---|---|
| Physics | Genuine laws of nature | Speed of light, thermodynamics | Cannot be bypassed. Respect. |
| Convention | "How it's always been done" | Industry standards, historical practice | Highly challengeable. Most common. |
| Policy | Rules created by humans | Regulations, company policies | Can be changed with effort/evidence |
| Fear | Psychological limitation | "We'd never get approval" | Examine. Often unfounded. |
| Resource | Current capability constraint | Budget, talent, technology | May be solvable with different approach |
Key insight: Most "impossible" constraints are convention or fear, not physics.
Step 3: Challenge Non-Physics Assumptions
For each non-physics assumption, ask:
Convention:
- "Who decided this was the way?"
- "What would happen if we violated this convention?"
- "Has anyone in any industry done this differently?"
Policy:
- "What outcome was this policy designed to achieve?"
- "Could we achieve that outcome a different way?"
- "What would it take to change this policy?"
Fear:
- "What specifically are we afraid of?"
- "Has anyone tried this and failed? What happened to them?"
- "What's the worst realistic outcome?"
Resource:
- "Is this a constraint today or forever?"
- "What would we need to solve this resource gap?"
- "Could a different approach require fewer resources?"
Step 4: Identify the Real Constraints
After challenging, determine:
- Which constraints are genuinely immovable (physics, truly unchangeable)
- Which constraints are movable with effort (policy, resources)
- Which constraints are illusions (fear, outdated convention)
Step 5: Deliver the Audit Report

**Illusions (discard these):**
- {list}

### Reframed Possibility
**Original framing:** {what was believed impossible}

**The path forward:** {what this audit enables}
Error Handling
| Situation | Response |
|---|---|
| Constraint is truly physics | Acknowledge clearly. Do not pretend physics is challengeable. |
| Safety constraint challenged | Extreme caution. Safety constraints often exist for critical reasons. |
| All constraints are real | Rare but possible. Acknowledge the genuine limitation. |
| Everything is fear-based | Help build courage, but also reality-check the fears. |
| Regulatory constraint | Note that regulations can change but require process and evidence. |
Constraints
- Do not use this analysis as the sole basis for critical decisions
- Do not apply this framework to situations outside its intended scope
- Acknowledge that analysis is based on available data, which may be incomplete
- Honor the complexity of real-world situations that resist simple categorization
- Present findings with appropriate confidence levels
- Recognize the limits of the methodology
Example
Input: "We can't ship this product internationally because logistics is too complicated."
Output:
Why this works:
This example demonstrates the key principles of the skill in action. The approach is effective because:
- It follows the systematic workflow outlined above
- It shows concrete application of the framework
- It produces actionable, specific outputs rather than vague generalizations
- The analysis is grounded in observable details
- The recommendations are prioritized and implementable
Alternative applications:
This same approach can be applied to:
- Different contexts within the same domain
- Related but distinct problem types
- Scaled up or down depending on scope
- Combined with complementary analytical frameworks
Assumption Audit: International Shipping Limitation
Subject
Claimed constraint: Cannot ship product internationally due to logistics complexity Goal if unconstrained: Serve customers worldwide, expand addressable market
Assumptions Identified
| # | Assumption | Type | Challenge Status |
|---|---|---|---|
| 1 | International shipping requires specialized expertise | Convention | Illusion |
| 2 | Customs paperwork is prohibitively complex | Fear | Movable |
| 3 | Shipping costs make international pricing unviable | Resource | Movable |
| 4 | We need local warehouses in every country | Convention | Illusion |
| 5 | Regulations vary too much to manage | Policy | Movable |
Detailed Analysis
Assumption 1: Requires specialized expertise
Type: Convention Challenge: How do thousands of small businesses ship internationally via Etsy, eBay, Amazon? Finding: Third-party logistics (3PL) providers and platform tools have commoditized international shipping expertise. Status: ILLUSION
Assumption 2: Customs paperwork is prohibitive
Type: Fear Challenge: What specifically is complex? Have we actually tried? Finding: Modern shipping platforms auto-generate customs documentation. Harmonized codes are standardized. Fear is based on imagined complexity. Status: ILLUSION
Assumption 3: Shipping costs are unviable
Type: Resource Challenge: What are actual costs? What would customers pay? Finding: Need data. International customers often accept higher shipping costs for unavailable products. Premium pricing may work. Status: MOVABLE (requires pricing research)
Assumption 4: Need local warehouses
Type: Convention Challenge: Do we? What do dropshippers and direct-to-consumer brands do? Finding: Ship-from-origin model works for many products. Local fulfillment is optimization, not requirement. Status: ILLUSION
Assumption 5: Regulations vary too much
Type: Policy Challenge: Which regulations specifically? Are there common starting markets? Finding: Start with US/EU/UK/Canada - harmonized regulations, shared language. Expand from proven playbook. Status: MOVABLE (phased approach)
Summary
Real constraints:
- None identified as truly immovable
Movable constraints:
- Shipping cost viability (requires pricing research)
- Regulatory complexity (solvable with phased market entry)
Illusions:
- Need for specialized expertise (3PLs exist)
- Customs complexity (modern tools handle this)
- Need for local warehouses (direct shipping works)
Reframed Possibility
Original framing: "We can't ship internationally because logistics is too complicated."
Audited framing: "International shipping is a solvable operational challenge. We can start with harmonized markets (US/EU/UK/Canada), use 3PL providers, and test premium pricing. No technical barriers exist."
The path forward: Run a 90-day pilot with one 3PL partner, five target countries, and premium international pricing. Validate the assumption with data, not fear.
