Skywatch is an aviation situational awareness toolkit built as a Ruby gem. It pulls real-time weather and traffic data from public FAA, NWS, and ADS-B sources — no API keys, no subscriptions. Use it from the command line, from a Ruby script, or let a Claude Code subagent compose a full AIM 7-1-5 preflight brief in natural language.

What’s possible

Compose a full AIM 7-1-5 preflight briefing for any airport — adverse conditions, current METAR, TAF, winds aloft, Area Forecast Discussion, and more.

```sh
skywatch brief KCDW
```

Add a destination and a departure time for a corridor-aware route brief. Skywatch checks adverse conditions along the entire route.

```sh
skywatch brief KCDW --to KACY \
  --departing-at "2026-05-02T13:00:00-04:00"
```

Install the Skywatch Claude Code subagent and ask in plain English. The agent calls the CLI, parses the JSON, and presents the brief in AIM 7-1-5 order.

```
"Give me a weather brief for KCDW"
"What are conditions from KCDW to KACY at 1pm tomorrow?"
```
