# Contradiction Matrix Lookup

Query the TRIZ contradiction matrix for applicable inventive principles.

## Execution

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

## Why Subagent

Matrix lookup requires knowledge of the 39 engineering parameters and their intersections, plus interpretation of which principles are most relevant to the specific context. Benefits from dedicated analytical focus.

## Available SOPs

Optional, no fixed order; the final leaf is always a sop.

| SOP | When to use |
| --- | --- |
| spawn-agent | Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent. |
