Agents in Production: Patterns and Pitfalls

Real-world architectures, common failure modes, human-in-the-loop design, and keeping costs under control.

Production agents need guardrails around autonomy. Common architecture includes planner, executor, tool sandbox, memory layer, telemetry, and optional human approval for high-risk actions. The three failure modes below account for most real agent incidents. Run each one below, with the guardrail off and then on.

Production Guardrails

Pick a real failure mode, then toggle the guardrail to see the difference between an agent left to run free and one wrapped in a production safety net.

Common Pitfalls, Matched to Guardrails
Unbounded loops → a hard `max_iterations` cap. Hallucinated or unregistered tool calls → a tool allowlist validated server-side, not just described in the prompt. Uncontrolled token spend → a cost or token budget that forces an early, partial answer instead of an unbounded one. Missing observability and no fallback path turn any of the above from a caught error into a silent outage, so log every step regardless of which guardrails you add.

Design for recoverability. Every step should be traceable, retryable, and interruptible. Add checkpoints so workflows can resume without rerunning everything from scratch. The `code-review-agent` in the companion repo's human-approval gate (`--post` flag) is a simple version of this: the agent does all the work, but a human decides whether the result actually goes live.

Autopilot with Controls

A production agent should feel like a modern autopilot: highly capable, continuously monitored, and always overrideable by a human operator when needed.

Module Complete
You've gone from 'what makes a system agentic' through ReAct, alternative planning patterns, memory economics, multi-agent orchestration, real evaluation, and the production guardrails that catch real failures. The two companion projects, `research-agent` and `code-review-agent`, are the same patterns you just learned, running for real.
