yao-decision skillA
yao-decision is agent-read markdown (skill) from yaoapp/yao: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Decision Tools
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.
## decision_decide
Send a state (context) and one or more typed questions to a decision model.
### Question Types
| 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` |
### Basic usage (choice + noul):
```bash
tai tool decision_decide --state "Customer says: my billing is wrong, I was charged twice" --questions '{"department":{"type":"choice","instructions":"Route to the right department","criteria":{"billing":"Payment issues","technical":"Product bugs","sales":"Purchase inquiries"}},"is_urgent":{"type":"noul","instructions":"Is this urgent?"}}'
```
### With score question:
```bash

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
