Qwen Code users push for a real "disable auto-compaction" switch as hard tier fires at 85%
edwardyoon · ghdev · 2026-09-24
- A feature request on QwenLM/qwen-code argues that context.autoCompactThreshold only tunes the auto tier of the three-tier ladder (warn/auto/hard), and the hard tier always fires around 85% — there is currently no supported way to run a session that never auto-summarizes.
- The proposal adds an explicit switch like context.autoCompaction.enabled: false that skips all automatic compaction tiers while keeping manual /compact, following the common harness precedent of separating auto and manual triggers.
- The requester pairs Declarative Attention with KV cache offload on their inference backend, evicting long-lived context to an external store — but Qwen Code's forced compaction reintroduces the lossy-summary problem they're trying to eliminate.
