ChatGPT co-inventor's notes: a 100ms context filter in front of Claude Code to kill compaction

- ChatGPT co-inventor (CompleteSkeptic) shared notes on typesafe coding agents, targeting Claude Code's core flaw: it carries the entire chat history into every turn, getting slow and expensive after a few messages.
- His fix: put a lightweight component called Jev in front of Claude to decide in 100ms what actually needs to stay in context — every message, tool output, and file — essentially killing compaction.
- Counterintuitive point: model routing can cost MORE, since the big model still re-reads everything anyway.
- He hopes the community builds on it; the retweeter is already wiring this into their agency's Claude Code setup.
