Compaction is triggered at 50% with GPT-5.6 Luna Max #4571
Description
Describe the bug
When using Copilot CLI with GPT-5.6 Luna Max (maybe other effort levels also), compaction is triggered at 50%. Implementing even smaller tasks almost always trigger compaction because of that.
Affected version
GitHub Copilot CLI 1.0.80
Steps to reproduce the behavior
Use Copilot CLI with GPT-5.6 Luna Max let it work on a task. At 50% context window, compaction triggers.
Expected behavior
Should happen at approximately 80% of the context window's capacity.
Additional context
- MacBook Pro - M2 Pro
