**id**

required

string

\>= 1 characters

**tenantId**

required

string format: uuid

**projectId**

The test set’s project: every version of a test set is in the one project. Absent when the runtime doesn’t record it: a pack `kindgi dev` serves from disk, or a runtime before Kindgi 0.1.6.

string format: uuid

**version**

required

Semver — publishing a modified suite produces a new version.

string

/^\d+\\.\d+\\.\d+$/

**kind**

required

string

Allowed values: accuracy pairwise regression human-review benchmark custom judged

**description**

string

**spec**

required

Kind-specific suite body. For `accuracy`, typically `{ cases: [{ input, expectedOutput }], grader?: { adapterId, config? } }`. For `pairwise`, typically `{ prompts, variantA, variantB }`. For `regression`, typically `{ baseline, cases }`. For `human-review`, typically `{ rubric, reviewerRole }`. For `benchmark`, typically `{ benchmark: { name, version } }`. For `custom`, typically `{ handler: { modulePath, entrypointPath }, cases }`.
