# 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.
