# Insurance claim intake

Source: https://docs.temprl.org/examples/insurance-claims

> Read claim dates and amounts, compute filing deadlines with exact arithmetic, check coverage and route claims with Simo derive and Task.

Read each claim, compute how late it was filed with exact date arithmetic, check coverage against the policy, and route it. Claims that aren't clear-cut go to an adjuster with the reason attached.

**Python**

```python
from simoai import Client, Task, Choice, Extract, Fill, Noul, days_between

c = Client()

POLICY = """Home policy HP-2207. Covers water damage from burst pipes and storm damage.
Excludes flood from rising water and gradual leaks. Claims must be filed within 30 days of the incident."""

intake = Task(
    questions={
        "policy_no": Extract("the policy number", max_tokens=12),
        "incident":  Extract("the date of the incident, exactly as written", max_tokens=12),
        "filed":     Extract("the date the claim was filed, exactly as written", max_tokens=12),
        "amount":    Fill("the amount claimed, in dollars", kind="number"),
        "covered":   Noul("The loss is covered by the policy"),
        "late":      Noul("The claim was filed more than 30 days after the incident"),
        "route":     Choice("Where does this claim go?", {
            "deny":       "not covered, or filed too late",
            "adjuster":   "covered but large or complex",
            "fast_track": "covered, small and clear",
        }),
    },
    derive={"days": days_between("incident", "filed", "days from the incident to the claim")},
    act_at=0.9,
    read_at=0.8,
    check=lambda v: ["fast-track over $5,000"] if v["route"] == "fast_track" and (v["amount"] or 0) > 5000 else [],
)

claim = """Policy HP-2207. On September 2, 2026 a pipe under the kitchen sink burst and flooded the floor.
Repair quote attached: $3,180. Submitted October 1, 2026."""

res = intake.run(c, {"policy": POLICY, "claim": claim})

if res.ok:
    print("route:", res["route"], "| days:", res["days"])      # route: fast_track | days: 29
else:
    print("to an adjuster:", res.review)
```

## Why it works

- **Reads first, then decisions.** A task with both reads and decisions turns on `two_pass` by itself.
- **The model reads; the arithmetic is exact.** `days_between` computes 29 days from the two dates read, and the `late` decision sees "days: 29" instead of counting on its own.
- **Your rules stay in code.** The $5,000 fast-track cap is a `check`, not a sentence the model might weigh differently.
- **Every hand-off has a reason.** `res.review` lists which decision or read fell short, so the adjuster starts from the right place.
