# Categorize Papers

Cluster papers by theme/method/timeline into natural groupings.

## Execution

Subagent — spawned via subagent-spawning/spawn-agent skill.

## Why Subagent

Categorization requires holding the entire paper collection in context simultaneously to identify patterns and groupings. Subagent provides dedicated space for this comparative analysis.
