I've been using claude-bridge [0] and pi-vcc [1] for compaction and it has been a complete life changer. I'm slowly phasing out my Anthropic use for Mistral but I've used it for months without issues.

That compactor does not use any LLM calls and you find it sufficient? I'm surprised that works well.
