## reach\_person()

For outbound calls, `reach_person()` handles the critical first step: confirming you have the right person on the line before proceeding. It automatically handles answering machines, gatekeepers, wrong numbers, and refusals.

### What happens on the call

When `reach_person()` is invoked, the agent automatically:

1. **Greets** whoever answers and introduces itself (organization + purpose).
2. **Asks for the contact** by name. If someone else answered, asks to speak with or be transferred to the contact.
3. **Determines availability** and records the contact's availability in a `contact_availability` field.
4. **Fires `agent.on_reach_person`** with the outcome key (`"available"`, `"unavailable"`, or a custom outcome if you provided `outcomes`).

### Common mistake: redundant introductions

<Callout>
  <span className="text-primary font-semibold">Warning:</span> By the time `on_reach_person` fires, the agent has already introduced itself and stated the purpose of the call. Do **not** re-introduce in the first task after `reach_person`.
</Callout>

```python
# WRONG — redundant introduction
@agent.on_reach_person
def on_reach_person(call: guava.Call, outcome: str):
    if outcome == "available":
        call.set_task("survey", checklist=[
            guava.Say("Hi, this is Grace from Acme Corp, I'm calling about..."),  # Already said this
            ...
        ])

# RIGHT — go straight to content
@agent.on_reach_person
def on_reach_person(call: guava.Call, outcome: str):
    if outcome == "available":
        call.set_task("survey", checklist=[
            guava.Say("I just have a few quick questions for you today."),
            ...
        ])
```
