Session automatically compacted, destroying the entire working context

[raymelon]

Is this a normal behavior? The agent basically forgotten everything about the session.

It's a hassle to refresh the agent on the task at hand, let alone make it remember about every key detail about the session.

I just don't think compacting the session in the middle of build mode is ideal as well. It can cause the agent to go haywire since it starts to assume outrageous things.

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

• compact causes llm to forget convo #2234: compact causes llm to forget convo - Similar issue where Claude forgets conversation after compaction
• Content hidden behind prompt #2736: Remove auto-compact (or at least don't default to having it on) - Discusses how auto-compact makes the agent forget critically important context
• I can not configure the limit for litellm #2787: bug: Q is too eager to compact the context window - Reports premature compaction that causes the agent to lose its train of thought
• Enhance theme documentation with links #2707: Context summarization loses current working directory and project location - Shows how compaction causes loss of important context like working directory
• Preload instructions after /compact #940: Preload instructions after /compact - Indicates that instructions are also lost during compaction

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

You can /undo the compaction. I know it is not ideal but you get back to the previous state.

How can we set OPENCODE_DISABLE_AUTOCOMPACT in the opencode.json?

[rekram1-node]

@fkukuck you just need to export OPENCODE_DISABLE_AUTOCOMPACT

I've opened a PR to set this setting easier
