12-Factor Agent Methodology(12FA)
Production-ready methodology adapting 12-factor app principles for scalable, maintainable agent systems with comprehensive monitoring and evaluation.
In 30 seconds
- What
- Applies twelve software engineering principles to agent systems for consistency, observability, and scalability across environments.
- When to use
- Building production agent systems that need to scale horizontally, run reliably across environments, and maintain visibility into costs, performance, and correctness over time.
- Watch out
- High upfront complexity and infrastructure overhead; teams often over-engineer early or struggle to implement all twelve factors consistently without dedicated DevOps support.

Find out what your evals miss
Measuring an agent is harder than shipping one, and most suites stay green while production drifts. Have your evaluation setup reviewed end to end: what you measure today, what you cannot see yet, and the regressions your current suite would let through.
