   This issue might be a duplicate of existing issues. Please check:

   • [Feature Request] Add User Controls for Context Management #1990: [Feature Request] Add User Controls for Context Management - requests manual control over context including commands like /tokens and /clear, which relates to wanting manual control over compaction timing
   • github copilot: 2x token (counts total=total+cached) compacts at 64k, instead of 128k #3314: 2x token reported in TUI (share link obj ok) - compacts too early - reports that auto-compact is triggering too early, which aligns with your concern about auto-compact not working as expected
   • auto-compact not working before maxTokens errors from provider #668: auto-compact not working before maxTokens errors from provider - discusses issues with auto-compact timing and behavior

   Feel free to ignore if none of these address your specific case.

   There are two environment variables that could help you out:

   OPENCODE_DISABLE_AUTOCOMPACT : This controls whether opencode triggers the a compaction when the token usage exceeds the context window. This should happen very infrequently.

   OPENCODE_DISABLE_PRUNE: This control whether opencode automatically triggers pruning old tool call results to save context window.

   I think what you want is setting OPENCODE_DISABLE_PRUNE to true, this will preserve everything in the context and then you can run /compact yourself when you want to.

   I've found the default auto compact behaviour to be very frustrating for my use case. I put a lot of effort into building specific context windows for research, and having that context disappear unexpectedly is a huge blow to productivity. I really feel that this should be an opt-in setting rather than the default.

   Absolutely hate auto-compaction to be honest. Continue with this kind of "features" and I will start using a fork of opencode or another competitor. Who was the genius behind this "feature"? Fake instructions telling the computer to continue if it knows what to do? Which leads to enormous production problems? Compacting without warning? What is wrong with you people? Who is responsible for UX/UI at opencode? Hint: hire someone from Tokyo for UX/UI. Those Nintendo guys are excellent at understanding user's feelings.

   You have to protect your user's feelings. Don't you understand that? Don't annoy the users. Make the users feel warm and safe, like a mother cradling its child. There is no contradiction between this and technical excellence.
