# Mitigation Design SOP

Designs three-layer countermeasures (prevention, detection, response) for high-priority failure modes.

## Execution

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

## Why Subagent

Mitigation design requires creative problem-solving focused on solutions, isolated from the analytical mindset of failure identification.

## Input

- **high_priority_modes**: H-priority failure modes with chains
- **chains**: Full cause-mode-effect chains for context
- **function_tree**: Function structure for integration points

## Output

- **mitigations**: For each H-priority mode: prevention, detection, and response measures
- **implementation_notes**: Feasibility and resource requirements
- **residual_risk**: Expected risk remaining after mitigation

## 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. |
