Agent Systems Need Reviewable Intermediate Artifacts
One reason agent systems can feel slippery in production is that too much of the workflow disappears behind the final answer. By the time something looks wrong, the intermediate planning, evidence shaping, and constraint decisions are already compressed away.
That is a tooling problem as much as a modeling problem.
Final Outputs Hide Too Much
If the only artifact that survives is the final response, incident review becomes harder than it should be. You can see the bad outcome, but not the specific places where the process got thinner, noisier, or overconfident.
That is why I prefer workflows that preserve intermediate artifacts such as:
- evidence bundles
- plan revisions
- support-strength summaries
- uncertainty markers
- escalation reasons
These do not need to be pretty. They need to be inspectable.
Reviewability Is a Reliability Feature
Reviewable intermediate artifacts help because they make it possible to ask:
- what evidence actually existed at this step?
- what changed before the answer became stronger or weaker?
- what information was dropped?
- what triggered escalation or fallback?
Without those artifacts, supervision ends up inferring the workflow from its final prose, which is much less reliable.
The Practical Standard
Agent systems improve faster when the important internal steps are visible enough to inspect after the fact.
That does not mean storing every token forever. It means keeping the artifacts that explain:
- what the system knew
- what it decided
- why it changed course
A reviewable workflow is easier to debug, easier to score, and easier to trust than one that only leaves behind the final answer.
