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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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

How to install
mdr add yaoapp/yao/yao-decision@sha256:b4b5a25e5988976eThe line at the top of this page pins the label git:20260922.00b711e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
