Moda Production Pattern: Haiku Triage Node Classifies Format → Pre-Loads Relevant Skills → LangSmith Traces as Primary Regression Detection Loop

LangChain Blog·medium signal

Moda's AI design platform routes every request through a lightweight Haiku triage node (fast, cheap) that classifies output format (slide deck, PDF, carousel, logo) and pre-loads only relevant skills — markdown playbooks with design best practices and format-specific instructions. LangSmith traces serve as the primary feedback loop, with the team iterating on context representation by comparing traces to understand how structure affects agent behavior and cost.
