Production
PoC agents work in front of their author. Production agents work without one. This lesson is the loop that bridges the gap: instrument what the agent does, guard what it can do, roll out changes carefully, and keep cost predictable — then iterate every time reality teaches you something new.

The PoC-to-Production Gap
Most agent demos succeed in controlled settings and fail in production. The recurring causes:
- Non-determinism — Same input, different output
- Latency — Multi-step loops add seconds to minutes
- Cost surprises — Unbounded loops and large contexts make spend unpredictable
- Reliability — Multi-step workflows fail in more ways than single requests
- Discovery lag — Weak telemetry leaves users to report failures first
Each is a symptom of the same thing: in the demo, a human filled in for the missing infrastructure. Production replaces the human with deliberate scaffolding around the agent.
The Production Loop
The scaffolding is a closed loop. Each turn improves the agent or the loop itself.
