AI Systems Drift Without Documentation

AI agents are sensitive to small changes in prompts, context, and tooling. A tweaked system prompt. A new tool. A different file structure. Each change nudges behavior. Over time, without a record of what the system was supposed to do, behavior gradually diverges from expectations.

Documentation is not just for humans. It stabilizes AI systems. When you document how the system works—what each agent does, what inputs it expects, what outputs it produces—you create a reference that both humans and future agents can use. Updates can be checked against the doc. Drift becomes visible.

Documentation is not just for humans—it stabilizes AI systems as well.
