## Appendix VIII: Applying 12-Factor Agents Principles to the DACA Design Pattern for Reliable LLM-Based Multi-Agent Systems

[Applying 12-Factor Agents Principles to the DACA Design Pattern for Reliable LLM-Based Multi-Agent Systems](https://github.com/humanlayer/12-factor-agents/blob/main/README.md)


**In a nutshell:** DACA already “speaks” the 12-Factor Agents language. Its MCP-based tool calls, Dapr-centred state model, event-driven APIs, and human-in-the-loop hooks line up almost one-for-one with the twelve prescriptions, while its Kubernetes/Docker foundation embodies the original 12-Factor App ideals. The table and notes below show exactly where each factor shows up in the DACA guide—and where you may still need to add glue or guard-rails.
