Feature Request: Configurable compaction threshold percentage #16204
Description
Description
It would be great to have a configurable threshold for when auto-compaction triggers, specified as a percentage of context window usage.
Use Case
Instead of compaction only triggering when context is ~100% full, users should be able to set a percentage (e.g., 50-62%) to proactively compact before hitting limits.
Proposed Solution
Add a new config option like:
{
\"compaction\": {
\"auto\": true,
\"threshold\": 0.5, // 50% of context window
\"prune\": true,
\"reserved\": 10000
}
}Or alternatively, a percentage string:
{
\"compaction\": {
\"threshold\": \"50%\"
}
}Current Workaround
Currently users can set a high reserved value to force earlier compaction, but this isn't precise and doesn't achieve the same goal.
Context
- Model: antigravity-claude-opus-4-6-thinking (200k context)
- User request: trigger compaction at 50-62% token usage
Thanks for considering this!
