Build input spaces for two source concepts, elaborating each into its elements, relations, and attributes.
Subagent — spawned via subagent-spawning/spawn-agent skill.
Input space construction requires deep elaboration of each concept's internal structure, identifying non-obvious elements and relations. Benefits from dedicated focused attention on each concept independently.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted, and 20 counted toward the lift figure. The other 2 produced results that are not comparable between the two arms, so they are excluded from the headline rather than averaged into it. The headline lift of -5 percentage points is the difference between those two pass rates over the 20 comparable cases. 2 cases got worse with the skill loaded, and they are included in that figure.
Other measured skills in the registry, with their headline benchmark lift.
