Alex Volkov: Jev as an instant compaction plugin for Claude

Volkov shows a community plugin (tamaratran/fast-jev-compaction) that uses Jev to score and drop unnecessary tool calls; he says it took about 1 second to cut a Claude session from nearly 1M to 86K tokens. User-reported, not benchmarked.

This is actually insane. This uses @typesafeai Jev model, as a plugin in Claude to review all the un-nesseasary tool calls, and it takes 1s to run!

Like, literally, 1 second to take my Claude session from nearly 1M to ... 86K tokens! 😮

Ask your claude to install it and be amazed

Use this prompt

Install, and configure :

Quoting @tamarajtran: found the perfect use case for @typesafeai Jev:

instant compaction

in 2026, why is compaction still a summarization prompt?

Jev can make it instant by scoring every tool call and dropping what’s irrelevant
