xby-caltrain

In the San Francisco Bay Area, Caltrain is a mainstay commuter line linking the South Bay to the North Bay. But checking a single departure typically means leaving the chat for a browser or a transit app, breaking the flow of an ongoing conversation or work session. xby-caltrain brings that lookup directly into the chat window: name your origin and destination, and the next scheduled departures appear instantly.

Built on GTFS (General Transit Feed Specification) data, the plugin covers three core tasks. First, it fetches the upcoming Caltrain departures between any two stations. Second, it lets you query departures at a specific ISO-8601 timestamp, so you can plan around a meeting or a deadline. Third, it lists every available station, which helps resolve naming or spelling issues when a lookup returns a not-found error. Station names accept common abbreviations such as SF for San Francisco and SJ for San Jose, lowering the input barrier.

Setup is a single step: set the API key once and it persists across restarts, so there is no repeated configuration. The plugin is best suited for regular Caltrain commuters, remote workers who need to confirm train times mid-conversation, and anyone who wants to handle Bay Area transit lookups seamlessly within DeepSeek Harness without ever leaving the chat.
