trein
This skill provides a CLI `trein` to query Dutch Railways (NS) for departures, trip planning, disruptions, and station search. It requires the `NS_API_KEY` (via `export NS_API_KEY="your-api-key"` or `~/.config/trein/trein.config.json`) and instructs installing/running the `trein` binary which accesses `https://apiportal.ns.nl/` and GitHub release URLs.
