# Method-Problem Crossing
Build a cross-reference matrix of methods × problems, documenting which combinations have been explored.
## Execution
Subagent — spawned via subagent-spawning/spawn-agent skill.
## Why Subagent
Matrix construction requires systematic cross-referencing of many method-problem pairs. Benefits from dedicated context to track all cells without losing state.
