Failure Chain Construction

Builds multi-level cause → mode → effect chains for systemic failure understanding.

Execution

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

Why Subagent

Chain construction requires disciplined causal reasoning without skipping levels. Isolated context prevents shortcutting.

Input

• failure_modes: Structured failure mode catalog
• function_tree: Function decomposition for context
• depth: Max chain depth (2/4/6 per budget)

Output

• chains: List of cause-mode-effect chains with level annotations
• shared_causes: Root causes appearing in multiple chains
• cascade_risks: Modes that trigger other modes

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.
