Subclaims¶

q1 i? CogTax defines a command's level as L = max(C, O), so a command at level L requires at least level-L understanding or produces at least level-L effects, but not necessarily both. → Alonso-Carracedo 2026

q1 · i? · design · r2

Definitional statement of the taxonomy's combination rule in the methodology section. The article presents the maximum rule as ensuring "monotonecoverage" so that conceptual mastery alone is insufficient if operational awareness is absent, and conversely. No empirical test of the rule itself is reported in the available text.

"The taxonomy level of a given command is defined by Equation (1). This formula ensures monotonecoverage: acommandat levelLrequiresat leastlevel-Lunderstanding orproduces"

Related Claims¶

• An AST-only structural classifier substantially exceeds random baseline accuracy in predicting CogTax levels, with L1–L3 mutually confused and L4 perfectly precise — related
• A combined AST-plus-embedding classifier achieves 89% accuracy assigning CogTax levels to 585 expert-annotated Linux/bash commands, outperforming either representation alone — related
• All four LLMs award a smaller share of available marks as bash question cognitive complexity increases, with L4 questions receiving the lowest proportions — related
