Systematic stress testing of assumptions — surface, classify by vulnerability, attack, assess fragility. Combines assumption-surfacing (shared), abp-vulnerability-classification, and clr-validation SOPs.

Tokens, turns and time describe resource use, not a dollar price.
This benchmark measured an earlier version of the skill.
One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.
In stress-testing the assumption 'AWS infrastructure will maintain 99.99% uptime' for FleetTrack, the engineer defines 'vulnerability' as the monthly dollar cost of hosting. Evaluate vulnerability according to the standard methodology.

The instructions your model reads when the skill loads.
Expose load-bearing assumptions, classify their vulnerability, perturb them, and re-check causal validity.
required: [claim_or_model, assumptions]
optional: [evidence, causal_graph, perturbation_bounds]
constraints: [each assumption must be traceable to a claim or causal link]
Do not perform called SOP operations inline; each loaded SOP owns its contract and thresholds.
surface-assumptions to surface load-bearing assumptions.classify-assumption-vulnerability to classify their vulnerability.challenge-assumption to challenge each material assumption.apply-perturbation to apply bounded perturbations.validate-causal-link to re-check affected causal links.
If the surviving result requires broader model and scaling variants, consider robustness-analysis as the next tactic.
Deviation: omit perturbation only when the assumption is purely definitional; still record and classify it.produces: [assumption_register, vulnerability_map, perturbation_results, causal_recheck]
delta_fields: [findings, assumption_updates, uncertainties, decisions, open_questions]
Do not call a model robust when an untested high-vulnerability assumption carries the conclusion or when perturbation bounds are unstated.
