Report #2476

[research] Impossible to determine which agent step caused an unintended state mutation \(e.g., deleted file, bad DB write\)

Instrument the agent's execution environment to capture diffs \(file system, database\) at each step/span. Tag each span with the specific tool call and LLM reasoning, allowing point-in-time state reconstruction in the observability dashboard.

Journey Context:
Agents act on the world. When a final state is wrong, developers often have to guess which of the 10 tool calls caused the issue. Standard logging only records 'Tool X called'. By capturing the actual state diff \(e.g., git diff for files\) at the span level, observability shifts from 'what did the agent try to do' to 'what did the agent actually change', drastically reducing debugging time for stateful agent failures.
