User

I'm in Istanbul and want to go for a run this afternoon. Is that a good idea, and when should I head out?

Thinking

Before recommending a time I should check three things: the weather, the air quality, and whether the user is actually free this afternoon. I'll call the tools one at a time and reason about each result.

Claude

Good question — let me check a few things for you.

Tool callget_weather()

{
  "city": "Istanbul",
  "when": "today"
}

Resultget_weather

22°C, clear skies, wind 12 km/h, sunset 19:48.

Claude

Weather looks ideal. Now checking the air quality.

Tool callget_air_quality()

{
  "city": "Istanbul"
}

Resultget_air_quality error

AirQuality API timed out after 5000ms.

Claude

The air quality service is down — I'll note that and proceed without it.

Tool callget_calendar()

{
  "date": "today",
  "part": "afternoon"
}

Resultget_calendar

Free 13:30–17:15. Event 'Design review' starts 17:30.

Claude

Yes — this afternoon is a good window for a run. • Head out around 14:30. It's 22°C and clear, with a light 12 km/h wind. • Finish by ~16:45 so you have time to cool down before your 17:30 Design review. • I couldn't confirm air quality — the service timed out — so if you're sensitive to it, glance at a local app before you leave. Have a good run!
