[Bug] Context Auto-Compact Triggered Unexpectedly on Model Switch

Resolved 💬 3 comments Opened Oct 13, 2025 by julianj Closed Oct 17, 2025

Bug Description
if you're switching from a session of claude-sonnet-4-5-20250929[1m] to something with lower context. As soon as you switch, your context will be ready to auto-compact, and you might loose all or a big chunk of your context. You might even see an error like this:

/compact

⎿ Error: Error during compaction: Error: Conversation too long. Press esc twice to go up a few messages and try again.

It'd be great to get a message before switching. or the ability to compact the context before switching
