Criterion Runs

A Criterion Run is the result of running a single Criterion against a Task Run. The verification engine creates one Criterion Run per criterion when a task run completes.

Endpoints

Method	Endpoint	Description
`GET`	`/criterion-runs?task_run_id={task_run_id}`	List criterion runs for a task run
`GET`	`/criterion-runs/{id}`	Get criterion run details

Criterion Runs are read-only. They are created automatically when you complete a task run (see the Task Runs page and the v1 completion flow).

Criterion Run Object

Field	Type	Description
`id`	string	Unique identifier
`task_run_id`	string	Parent Task Run
`criterion_id`	string	Source Criterion
`passed`	boolean	`true` if the criterion passed
`score`	number	Score (`0.0` to `1.0`)
`details`	string \| null	Human-readable explanation of the result
`evidence`	object \| null	Structured evidence payload (field-level results, matched messages, transcript snippets). Shape depends on the criterion’s check type

SDK Example

// List criterion runs for a task run
const runs = await verial.criterionRuns.list({ taskRunId: "tr_abc123" });

for (const run of runs.data) {
  console.log(`${run.criterionId}: ${run.passed ? "PASS" : "FAIL"} (${run.score})`);
  if (!run.passed) console.log(run.details);
}

// Fetch one criterion run with full evidence
const detail = await verial.criterionRuns.get({ id: "crun_01H..." });
