Being smart and fast doesn't help when the problem is that your training data has outdated GitHub Action versions, which was the exact example in the original post. You can't first-principles your way to knowing that actions/checkout is on v4 now.

More broadly, this response confuses two different things. Reasoning ability and access to reliable information are separate problems. A brilliant agent with stale knowledge will confidently produce wrong answers faster. Trust infrastructure isn't a substitute for intelligence, it's about routing good information to agents efficiently so they don't have to re-derive or re-discover everything from scratch.

It's a caching layer.
