In this brief discussion, Robert Ta and a co‑speaker emphasize a core safety practice for AI agents: maintain a source of truth that the agent cannot modify. They explain that immutable artifacts—such as a binary executable, on‑disk YAML configuration, system logs, or a metered cost counter—should be designated as the definitive reference for the agent’s actions. The conversation outlines concrete tactics: (1) for each investigative task, pick a single external oracle (e.g., the running binary, cost meter, logs) and verify any claim against that oracle; (2) when an agent claims its output is accurate, the verification must be against the chosen external source, not against another agent’s output; (3) any answer that relies on another agent’s output should be rejected. This principle is presented as essential language to embed in prompts to prevent agents from rewriting or self‑validating their own behavior, thereby reducing the risk of “agentic chaos.”

What do you think of this? Keep a source of truth outside the agent's reach.
Yeah, something it can't rewrite, right?
Yeah.
I thought that's a good clarification. I think we've even seen this in our codebase, right? If we have like, uh, say a schema that is meant to be a source of truth, an agent can easily go and overwrite that schema just so it like is consistent with the new code that it just wrote. If we're doing a ticket and we need certain changes to the system, we can say like, you know, these things are immutable and these are the things that you should change because the immutable parts are gonna be our source of truth. It's a good principle and I never quite thought about it that way before, but I guess it puts language to an idea that I think is like really critical to working with the agents.
And the specific tactics they give are number one, pick one external oracle per investigation, the running binary, the metered cost, the YAML on disk, the logs, check against that. When the agent says accurate, like they return something and say, hey, this thing's accurate, ask accurate against what? And reject any answer that is in itself another agent output.
If you can clarify in your scope and your prompting, like, what is immutable, then you avoid this kind of, like, paperclip maximizer logic.
