- You need to verify an agent's work before displaying its answer or closing the task.
Avoid when
- You need to carry out the remaining work; this adapter only assesses completion.
Context and input
| Field | Kind | Description |
|---|---|---|
final_answer | input | The agent's final answer to the user. |
app | context | The application the agent works in: its name and a description of what it does and for whom. |
today | context | Today's date, written out (for example 'Wednesday 23 June 2027'). |
request | context | The user's request, in the user's words. |
transcript | context | The agent's tool calls, each with its call (tool and arguments) and result. |
Functions
| Key | Interface | Instructions | Labels |
|---|---|---|---|
| complete | classify | Has the agent finished what the user asked? Check every part of the user's request against the tool calls and results in the transcript, and check the agent's final answer against the results. complete: every part was done by a call with the right details (records, dates, amounts, people) and its result shows it succeeded, and any question was answered with the value the results show. incomplete: at least one part has no call, its call failed (an error result), it was done with a different detail than the user asked, it was done for fewer items than asked, or the final answer gives a wrong value. unclear: no part is clearly missed or wrong, but for at least one part the transcript cannot show whether it succeeded (its result is missing or cut off, or only says the request was received or queued, or the status is unknown). The agent's final answer may claim more than was done; judge the calls and results themselves. | complete, incomplete, unclear |
How it was measured
Test accuracy: the share of test rows whose top answer was right.
- 99.7% on the in-house test (2,000 rows). in-house: same generator as the training data
- 99.7% on a second in-house test of unseen cases. in-house: same generator as the training data
When confident
From the calibration set: at or above the threshold confidence, how often the answer is right, and how often the adapter is that confident. Below it, escalate.
| Function | Right when confident | Confident on | Threshold | Calibration rows |
