Assumption Perturbation

Systematically perturb assumptions to identify which are load-bearing.

Operations

assumption-extraction → negation-definition → re-derivation → conclusion-sensitivity-measurement

Available SOPs

Subagent: assumption-extraction, negation-definition, re-derivation, conclusion-sensitivity-measurement Shared: assumption-surfacing Import: paper-research

Execution Guidance

Extract all assumptions (use shared SOP for initial surfacing), define weakest plausible alternative for each, re-derive the conclusion under each alternative, measure change magnitude and direction. Rank by sensitivity.

Key principle: negation is not logical NOT — it is the strongest plausible alternative. "Data is normally distributed" negates to "data follows a heavy-tailed distribution" not "data is not normally distributed."

Minimum Yield

<HARD-GATE>
- Assumptions extracted: >= 5
- Negations defined: >= 5
- Re-derivations completed: >= 4
- Sensitivity rankings produced: >= 1 complete ranking
</HARD-GATE>

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
conclusion-sensitivity-measurement	Quantify how much conclusions change across all assumption negations and produce a sensitivity ranking.
deep-insight-assumption-extraction	Systematically extract all assumptions (stated, implicit, boundary, mathematical, practical) from a method or model.
deep-insight-assumption-surfacing	Systematically extract implicit assumptions from methods, frameworks, or arguments. Identifies what is taken for granted without explicit justification.
deep-insight-paper-research	Full-text paper reading via three-pass Keshav method. Import of literature-engine/literature-research skill. Authoritative source for claims about paper content.
negation-definition	Define strongest plausible alternatives (negations) for each assumption to enable perturbation analysis.
re-derivation	Re-derive conclusions under a negated assumption, tracking where the derivation diverges from the original.
