| name | assumption-extractor |
| description | Use when someone presents a plan, argument, or belief with confidence and its hidden dependencies have not been examined — surfacing factual, causal, value, and definitional assumptions, then ranking which ones would collapse everything if wrong. |
| scenarios | ["Walk me through the assumptions behind this strategy","What am I taking for granted in this plan?","Is there something I'm missing before I commit to this?","이 계획의 숨겨진 전제가 뭘까?","내가 당연히 여기고 있는 것들을 찾아줘","이 논리에서 틀릴 수 있는 게 뭐야?"] |
| compatibility | {"recommended":["think-tool"],"optional":["sequential-thinking"],"remote_mcp_note":"think-tool이 있으면 네 가지 가정 유형(사실·인과·가치·정의)을 체계적으로 스캔하고 가장 위험한 전제를 정확하게 식별할 수 있습니다. Claude 설정 → MCP Servers에서 remote SSE 엔드포인트를 추가하세요."} |
Assumption Extractor
When to Use / When Not to Use
Use when:
- A plan or argument sounds solid but hasn't been stress-tested
- Someone is about to commit resources to a decision
- You want a pre-mortem before launching something
Not for:
- Identifying logical errors in reasoning (use fallacy-detector)
- Diagnosing why someone is overconfident (use bias-auditor)
Process
Step 1 — State the claim. Confirm the core argument/plan being examined.
Step 2 — Scan all four categories in parallel:
| Type | What to look for |
|---|
| Factual | What facts are assumed true without being established? |
| Causal | What cause-effect chains are assumed (A therefore B)? |
| Value | What is assumed to matter most? What trade-offs are pre-decided? |
| Definitional | What terms are assumed to share meaning? |
Step 3 — Classify by load.
- Load-bearing: if wrong, the argument collapses entirely
- Significant: if wrong, requires substantial revision
- Peripheral: if wrong, details change but core survives
Step 4 — Flag the most dangerous assumption. The load-bearing one with the lowest current verification.
MCP note: If sequential-thinking is available, run all four category scans before classifying — stopping after finding one load-bearing assumption misses others.

가정 추출 결과 / Assumption Map:
사실적 가정 / Factual Assumptions:
- [Assumption]: [Load-bearing / Significant / Peripheral]
인과적 가정 / Causal Assumptions:
- [Assumption]: [Load-bearing / Significant / Peripheral]
가치 가정 / Value Assumptions:
- [Assumption]: [Load-bearing / Significant / Peripheral]
정의적 가정 / Definitional Assumptions:

To verify: [What would need to be checked]
What Claude Does / What You Do
| Claude | You |
|---|
| Scans four assumption categories systematically | Provide the plan or argument to examine |
| Classifies each assumption by load-bearing weight | Confirm which assumptions are actually in play |
| Identifies the single most dangerous assumption | Decide which to test before committing |
| Names what would collapse if that assumption is wrong | Run the verification checks |
