Platform engineers built service mesh, identity, and FinOps. AI is the next platform layer they're inheriting — usually before anyone formally assigns it. Here's the mandate, the stack, and the four-stage maturity model.

An LLM proxy is the primitive behind many AI platform-engineering capabilities: capture, replay, policy, telemetry, and cost attribution. It's a small piece of infrastructure with a large surface of consequences.

If the session isn't captured, it isn't yours. AI session capture is the practice that turns disposable chats into a durable, queryable record — the substrate replay, telemetry, and governance run on top of.

Logs tell you an event fired. Replay lets you re-read the captured prompts, responses, tool-use events, and results that produced it — the only honest way to debug a system whose same input doesn't always produce the same output.

A complete behavioral record so you can answer what an agent saw, what it decided, and why—not just whether a request failed.

Telemetry captures what agents do. Observability makes that record interpretable and actionable. Both are essential when agents run in production.

Models are one layer; infrastructure is what makes agents repeatable, safe, and operable at scale.

A skill captures a reusable procedure, tool sequence, decision path, or troubleshooting pattern so future agent runs can reuse what already worked instead of rediscovering it.

A feedback loop: capture relevant sessions, analyze patterns, extract reusable artifacts, apply them to later runs, and measure whether outcomes improve. The model can stay the same. The system around it gets better.

One engineer's breakthrough session is a dead artifact until the team can search it, replay it, and invoke the skill extracted from it. Team-shared knowledge is the infrastructure that makes that possible.
