The README opens with

The plugin targets the current OpenCode plugin API rather than a pinned preview runtime. It uses the public experimental.session.compacting hook, fetches the current session transcript through the OpenCode client, asks Jev one set of narrow structured questions about tool evidence, and optionally appends compact guidance to OpenCode's native compaction prompt.

The plugin does not rewrite historical messages. This preserves the historical request prefix that provider prompt caching may reuse.
