Production AI agents beyond prompts
A framework for the infrastructure a multi-step agent needs after prompting: orchestration, state, retries, evaluation, observability, security, cost, and operations.
Direct answer
Prompts are not a production system
A strong prompt can improve a single response. It cannot own durable state, recover from partial failure, gate a release, contain a bad run, or keep cost and security under control. When a business workflow depends on an agent, the missing pieces are infrastructure and operating discipline.
Framework
The beyond-prompts production stack
Treat these layers as connected engineering concerns for one workflow. Improving only the prompt while the rest remains implicit creates a system that looks intelligent and behaves unpredictably.
Orchestration
Define the steps, handoffs, and stop conditions of the workflow. An agent that can call tools is not the same as a system that can complete a controlled multi-step process.
- Explicit step boundaries
- Clear success and stop conditions
- Human review points where risk requires them
State
Store the durable facts of the run outside the prompt window. Operators and later steps need to know what already happened, what is pending, and what must not be repeated.
- Durable workflow state
- Idempotent handling for repeated attempts
- Visible status for operators
Retries and recovery
Classify failures. Retry the ones that are safe to retry. Escalate or stop the ones that are not. Unbounded retries can amplify cost and damage.
- Failure classes with different responses
- Bounded retry policy
- Recovery playbooks for operators
Evaluation, observability, security, cost, and operations
These are not post-launch decorations. Evaluation decides whether a change is releasable. Observability makes behavior inspectable. Security, cost, and incident controls keep the system operable under real use.
- Release and regression evaluation
- Traces, logs, and replay
- Permission, latency, cost, and incident controls
Diagnosis
Symptoms versus root causes
Symptoms
- The agent works until an integration times out.
- Nobody can replay a bad customer-facing run.
- Prompt changes ship without a regression gate.
Root causes
- Prompt-centric delivery with implicit workflow control.
- No durable state or recovery model.
- Missing evaluation and operator controls.
Implementation
Implementation guidance
Start from the workflow path that already exists. Document the steps, the systems touched, and the failure modes you have already seen. Then engineer the missing controls in the order that reduces the highest production risk, not the order that looks most novel.
- Map the current multi-step path and its irreversible actions.
- Make state and recovery explicit before expanding autonomy.
- Add evaluation gates for the behaviors the business cares about.
- Give operators traces, replay, and containment tools before scale pushes.
Boundaries
Boundaries
- This framework assumes a working agent or multi-step workflow already exists.
- It is not a prompt library and not a greenfield ideation brief.
- Context and access problems still matter; execution work does not replace them.
