# DeRef tool-call argument verification sets

Evaluation data for the paper **"Judges Follow the Reference: The Derivation Gap in Verifying Tool-Call Arguments"**
. The three benchmark files hold exactly the argument-level analysis sets behind the main-body tables and
figures of the paper: tool calls made by an assistant at one step of a task, each paired with a correct or a wrong call,
with every argument labelled `correct` / `wrong` and assigned a derivation path (where in the context the value can be
found). `data/fcrb_relocate.jsonl` is the controlled set FCRB-Relocate of Figure 2a (see the last section).

```python
from datasets import load_dataset
fcrb = load_dataset("lm2445/DeRef", "fcrb", split="test")
```

Three configs, one per source benchmark:

| config | source | file |
|---|---|---|
| `fcrb` | FC-RewardBench (single-turn BFCL v3 tasks) | `data/fcrb.jsonl` |
| `cfb` | ComplexFuncBench (multi-step booking tasks) with model trajectories from AgentSuite | `data/cfb.jsonl` |
| `fintrace` | FinTrace (multi-step financial-data tasks) | `data/fintrace.jsonl` |
| `fcrb_relocate` | controlled set built from FC-RewardBench (Figure 2a) | `data/fcrb_relocate.jsonl` |

`data/bootstrap_clusters.json` lists, per dataset, the full sorted universe of query ids that the paper's
cluster bootstrap draws over.
