Chain

This is your orchestration layer for complex multi-step workflows. It forces you to map out sequential, parallel, conditional, or iterative tool chains with explicit data contracts between each step. The real value is in the structure: you define exactly what each tool consumes and produces, how failures propagate, and where retry logic kicks in. The mandatory prep step pulls in workflow principles and makes you think through error handling before you start chaining tools together. Useful when you're building pipelines that need to survive real world failures, not just happy path demos. The validation checklist alone will save you from the classic mistake of assuming step N output magically fits step N+1 input.
