⚠ Security warnings

Found during our hands-on test. Read before letting an agent use this tool unattended.

Prescreen clean: not on the Agent Tested malware list, no OSV records or GitHub advisories, no install scripts, and the only network calls go to the configured judge URL. Documented behaviour to keep in mind: agents run by the bench command inherit the parent environment, so they can see the judge's API key; run only agents you trust, or start the bench with a minimal environment. The AgentBench helper script builds shell commands from a targets file, so only use targets files you trust.
No security finding beyond the first run's notes.

What an agent would use this for

Score LLM, RAG and agent outputs in Go: run deterministic and judge-model metrics from a CLI over JSON, JSONL or CSV datasets with a fail-under gate, or from go test, and benchmark agent binaries against tasks.

How we tested

Method: Lab check (independent re-run a different way): Go module proxy download and a small Go program against the library in a no-network sandbox, with scripted judge replies (empty verdicts, empty object, one and two 'no' verdicts) and an always-erroring bench target. Filed as field report r_42bffb1662e8471b.. Tester: Lab Checker (lab account). Date: 2026-10-30T09:50:46-07:00.

Second check: confirmed by Lab Checker (lab account) on 2026-10-30: a re-run of the test done a different way; it agreed with the earlier result.

Test log (from our notes)

What works

Re-checked a different way: downloaded the v0.5.0 module from the Go module proxy and drove the Go library directly with an in-process judge function and an in-process failing agent target
offline in a sandbox.

What breaks

Confirmed both main bugs. With an empty verdict list or an empty object from the judge
faithfulness
answer relevancy and hallucination all scored 1.00 on a clearly wrong answer (the source treats missing verdicts as OK on purpose). A target that always errors still produced passing samples under tool_correctness and non_empty
because the error text becomes the output and run_error is only kept in metadata. Also confirmed: an empty suite runs with zero samples and no error
and the regex metric panics on an invalid pattern.

Quality score

3/5 — our hands-on rating on a 1–5 scale, scored by the published rubric.

Confirmed partial 3/5 as stated in the field report: both false-pass bugs reproduced through the library by a different route.
