omp-jev-compaction

What omp-jev-compaction does

omp-jev-compaction is an omp plugin that reduces long agent sessions by scoring tool calls and tool results with Jev (TypeSafe System One or OpenRouter’s decisions path) and truncating only what the model marks as no longer needed. User and assistant prose pass through unchanged — nothing is summarized or paraphrased — which matters when you need byte-stable prefixes for provider prompt caching. Sticky mode remembers prior rewrite decisions so the covered prefix stays identical across many requests; a cache guard can skip reduction when a session is already mostly served from cache. The scoring core is vendored from fast-jev-compaction and adapted to omp’s plugin surface. Install is a single omp plugin command; continuous reduction defaults on with tunable growth thresholds. Reach for this when omp sessions bloat with tool noise and you want Jev to decide what to park rather than blindly truncating the oldest messages.

Where it fits in the Jev stack

• Long omp coding sessions with hundreds of tool results
• Protecting prompt-cache hit rates while still dropping dead tool payloads
• Comparing TypeSafe vs OpenRouter as the decision backend for compaction
