# Constraint Identification SOP

Systematically discover all constraints that could prevent a candidate from being implemented. Applies three complementary methods: Theory of Constraints (find the bottleneck), TRIZ contradiction analysis (surface technical/physical contradictions), and Pre-mortem (imagine failure and trace causes).

## Execution

Spawns a subagent that:
1. Receives candidate description and implementation context
2. Applies TOC to identify system bottlenecks
3. Applies TRIZ to surface contradictions
4. Runs Pre-mortem to imagine failure scenarios
5. Deduplicates and returns consolidated constraint list

## Why Subagent

Constraint discovery requires creative, divergent thinking across multiple frameworks. Running as a subagent prevents premature filtering and ensures all three methods are fully applied.

## HARD-GATE

Output MUST include: at least 3 constraints identified, method attribution for each, and initial severity estimate. Reject if fewer than 3 constraints found.
