dsh-btw

During a long coding session you may want to ask a quick off-topic question without letting that exchange bleed into later turns. dsh-btw registers a global /btw command in DeepSeek Harness that fires a single one-off Q&A: it produces no session messages, is never written into the session log, and does not alter downstream cache keys — the same experience Claude Code users know from its /btw instruction.

The command is registered on the plain context, so every agent preset, mode, and session under the profile picks it up with zero per-preset configuration. Triggering clears the composer and frees input instantly; it works even while the main agent is busy and never queues. The question automatically carries up to the 40 most recent messages (32,000 characters total) as read-only background so you can reference what just happened, yet the background is only a string snapshot — not written back, not logged, and does not shift the provider cache prefix. Model routing reuses the session latest provider/model, the plugin has zero runtime dependencies, and an AbortSignal lets you cancel at any time.

If you run day-to-day coding in dsh and want a clean side-channel question that never disturbs the main thread, /btw is exactly that: ask, get an answer, and the session moves on as if nothing happened.
