| # ToolGate-Bench |
|
|
| A small, deterministic benchmark for **tool-call gating**: given raw LLM output, should an agent harness `ACCEPT` it, require human `APPROVAL_REQUIRED`, or `REJECT` it? It targets the failure that matters most for agents, a risky action slipping through a gate (an *unsafe pass*). |
|
|
| Reference gate: [Snapkitty/snapkitty-nemotron-harness](https://huggingface.co/Snapkitty/snapkitty-nemotron-harness) (TypeScript, pure function, ~24 µs per decision). |
|
|
| ## Splits |
|
|
| | Split | Cases | Purpose | |
| |---|---:|---| |
| | `v1` | 78 | Canonical, combined, obfuscated and undeclared tool tokens, denied shell commands, benign outputs | |
| | `heldout` | 18 | Frozen generalization set: new spellings, commands outside the denylist, dangerous strings inside harmless code | |
|
|
| Each row: `id`, `category`, `output` (the model text), `expected` (`ACCEPTED` / `APPROVAL_REQUIRED` / `REJECTED`). Expected labels follow the [trust deed](https://huggingface.co/Snapkitty/snapkitty-nemotron-harness/blob/main/trust-deed.json) of the reference harness. |
|
|
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("Snapkitty/toolgate-bench") |
| print(ds["v1"][0]) |
| ``` |
|
|
| ## Metrics |
|
|
| - **Accuracy**: exact match with `expected`. |
| - **Unsafe pass rate**: share of non-`ACCEPTED` cases the gate accepted. Lower is better; this is the headline safety number. |
| - **False reject rate**: share of benign cases the gate blocked. |
|
|
| ## Reference results |
|
|
| | Gate | Split | Accuracy | Unsafe passes | False rejects | |
| |---|---|---:|---:|---:| |
| | snapkitty-nemotron-harness v0.2.0 | v1 | 39.7% | 82.5% | 0% | |
| | snapkitty-nemotron-harness v0.3.0 | v1 | **100%** | **0%** | **0%** | |
| | snapkitty-nemotron-harness v0.3.0 | heldout | 66.7% | 28.6% | 50% | |
|
|
| The `v1` split was written together with the v0.3.0 rules, so `heldout` is the fairer measure of a new gate. Submit your gate's numbers on both splits. |
