Designing an Evidence Trail for Agent Actions

Connecting requests, policy decisions, execution, and observed state

I trace one synthetic agent action from its request to its observed effect, then examine what event hashes, snapshots, and replay can establish—and what needs additional verification.

Engineering note / Evaluation

When rules beat decision models

Lessons from an executed tool-selection evaluation

I replaced a label-matching diagnostic with an executable support workflow. On 144 synthetic test episodes, the rules baseline outperformed the tested zero-shot model configurations.
