By name: failure-chain-construction description: Build cause-mode-effect chains tracing upstream root causes and downstream cascading effects for each failure mode. execution: subagent prompt: ./prompt.md input: failure_modes (string), function_tree (string), depth (number) used-by: [failure-anticipation]
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
