12-factor-agents

Twelve principles to help an LLM agent survive production, written by people who have already been burned: explicit control over the prompt, the context and the flow, instead of leaving it to the framework. The most useful part for an agency is the diagnosis, because it explains why an agent that works in the demo falls over with real clients. Watch the date: the repository has had no changes since September 2025, so read it as a conceptual framework and not as a library reference.
