Load and validate the eval suites in a directory or file. Returns each suite name, its cases, the assertions declared on each case, and the threshold policy that gates it. Read-only — no model calls, no cost.

Read an evalgate result artifact (.evalgate/result.json) and explain why it passed or failed: which gates tripped, which cases failed, and the per-assertion explanation for each — including the claim-level grounding breakdown. Read-only.

Analyze .evalgate/history.jsonl for slow decline the per-PR regression gate cannot see. A case sliding a little each run passes every individual gate by construction. Reports per-series delta and slope. Read-only.

Read .evalgate/calibration.json and report the judge’s measured agreement with human scores. An uncalibrated judge is a random number generator with good manners — call this before trusting any rubric or grounded score. Read-only.

Run the suites at a path against a system-under-test module and return the scored result. EXECUTES the SUT module and may call model providers, so it can incur real cost. Writes nothing — the result is returned in memory, not saved as an artifact.
