Summary
Dex Horthy (HumanLayer) proposes 12 design principles for production-grade LLM agent systems, analogous to the 12-Factor App methodology. Key factors: (1) stateless computation, (2) own your prompts, (3) small context windows, (4) explicit tool boundaries, (5) human escalation paths. Each factor addresses a specific reliability failure mode observed in production.
PUMA Relevance
The 12 factors provide a design checklist for PUMA’s Stage 4–5 agents. Factors directly relevant: #4 (explicit tool boundaries → PUMA’s Pydantic AI schema validation), #5 (human escalation → PUMA’s HITL Constitution Article 4), #1 (stateless → PUMA’s LangGraph checkpointed state).
