Typed decision expert. ALWAYS invoke this skill when you need structured classification, scoring, or probability estimation — routing tickets, grading content, detecting intent, or any task requiring typed answers with calibrated confidence.
Use these tools when you need structured, typed decisions rather than free-form LLM text. Decision models return machine-readable answers with probabilities and confidence scores.
Send a state (context) and one or more typed questions to a decision model.
| Type | Purpose | Criteria | Answer Fields |
|---|---|---|---|
choice | Classify into one of N options | {option: description} map | choice, probabilities, confidence |
score | Rate on a scale | [level_labels] array | score, legend, probabilities, confidence |
noul | Estimate a probability (0-1) | (none) | noul |

Note:
modelin the response is the resolved concrete model ID (e.g.jev-1.13.0), not the alias you requested (e.g.jev-latest).
Batch states:
{
"results": [
{"state_index": 0, "answers": {...}, "model": "jev-1.13.0", "usage": {...}},
{"state_index": 1, "answers": {...}, "model": "jev-1.13.0", "usage": {...}},
{"state_index": 2, "error": "timed out after 60s"}
]
}
List available decision providers and their models.

Returns a list of providers with available models, connector IDs, and availability status.
state and states are mutually exclusive; provide one or the other.type (choice/score/noul) and instructions.criteria is required for choice (map) and score (array); noul must not have criteria.timeout defaults to 60s; values ≤ 0 are treated as the default.model is the resolved concrete model ID (e.g. jev-1.13.0), not the requested alias.
