judge
v0.2.0Provider-neutral evaluation hub (judge::evaluate, judge::cancel, and the internal judge::models::list) that forwards typed Noul, Choice and Score questions to the selected judge-<provider> worker; the default provider is a Console setting seeded from JUDGE_PROVIDER (typesafe). Also resolves worker-defined @<name>(id=…) chat mentions for agents (judge::mentions::resolve and a harness pre-generate hook).

judge
judge turns JSON state and Noul, Choice or Score questions into typed,
validated answers for ticket triage, content checks and relevance judgments.
It is a provider-neutral hub: every call is forwarded to a judge-
worker that owns the model, credentials and transport. The default provider is
judge-typesafe (TypeSafe JEV); other strategies plug in
by registering the same three functions under their own judge- id.
Install
iii trigger compose::add worker=judgeCompose starts the hub with its judge-typesafe dependency, which in turn needs
configuration. Use engine iii/v0.24.0-rc.2, the verified release used by
this repository's CI. Wait for judge::evaluate to register before calling it.
Quickstart
Set the TypeSafe key in the Console under Settings → Workers → judge-typesafe
or supply TYPESAFE_API_KEY in that worker's environment (see the
provider README). Then ask whether
a support ticket needs urgent attention:
iii trigger judge::evaluate --timeout-ms 65000 --json '{
"timeout_ms": 60000,
"evaluations": [{
"id": "ticket-42",
"state": {"ticket": "Production checkout is down for all customers."},
"questions": {
"urgent": {
"type": "noul",
"instructions": "Does this describe an urgent production outage?",
"criteria": {"true": "A critical production workflow is blocked."}
}
}
}]
}'A successful response looks like this; scores, usage and timing are illustrative:
{
"status": "ok", "model": "jev-1.13.0",
"results": {"ticket-42": {
"answers": {"urgent": {"type": "noul", "noul": 0.98}},
"usage": {"input_tokens": 120, "output_tokens": 8}
}},
"stats": {"attempts": 1, "requests": 1, "questions": 1,
"input_tokens": 120, "output_tokens": 8, "elapsed_ms": 250,
"usage_complete": true}
}Check status before reading answers. Errors return status: "error" and a
code with no partial results; provider_unavailable means the selected
judge- worker is not registered on the engine. A bus invocation
failure is handled separately. The hub adds 5 s of bus slack on top of your
timeout_ms; the provider enforces the deadline itself.
See the mixed Noul/Choice/Score example, result and error handling, model listing and cancellation.
Providers
Settings → Workers → judge selects the default provider from the workers
registered as judge- (seeded from JUDGE_PROVIDER, else typesafe);
a request may name its own with a top-level provider. A new provider is a
worker that registers judge-, ::models::list and
::cancel with the judge-contract types and
accepts request ids up to 512 bytes; the hub needs no change. See
Configuration and
Cancellation.
The hub holds no credentials; its configuration entry (judge, or
III_CONFIG_NAME) carries only the default provider. For the full API,
read reference.md; for the provider's build, configuration and
tests, read judge-typesafe.
