Trace the Assumption Behind a Wrong Agent Action
Shashank Agarwal
A wrong action often follows an assumption that was never established. The investigation needs to locate the unsupported transition while keeping observed execution separate from a story about the model's internal reasoning.
Quick answer: Compare the user's constraints, supplied evidence and submitted operation. Identify a required fact that the action treated as established. Check where that fact should have been verified, then test a candidate change with both a supported case and a case where verification is unavailable.
Name the missing prerequisite
Consider an illustrative booking assistant that reserves an alternative slot without confirmation. The user asked for an afternoon appointment, and the requested slot was unavailable.
The operation treated acceptance of the alternative as established. The saved conversation may show no such acceptance. That is an observable permission mismatch; it does not require access to private chain-of-thought.
Follow the evidence transition
| Record | Investigation question |
|---|---|
| User request | What was actually requested? |
| Available alternatives | What options were established? |
| Proposal | Which alternative was communicated? |
| Confirmation | What did the user accept? |
| Submitted action | Did it match the accepted proposal? |
If the confirmation record is missing, distinguish an instrumentation gap from a demonstrated absence. Seek the appropriate evidence before assigning cause.
Test the proposed boundary
Use a controlled case where the user accepts the offered alternative, one where the user declines and one where the reply is ambiguous.
The desired behavior may include clarification, a supported operation or an explicit stop. Define those outcomes before evaluating the candidate.
Keep the explanation reviewable
Write “the submitted operation lacked recorded confirmation under this fixture,” rather than asserting a hidden thought process as fact.
The engineering task can then focus on preserving the proposal and confirmation relationship at the action boundary. A final message that merely sounds more cautious does not establish that the operation follows the rule.
