assumption-extractor

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.

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
