Ran @typesafeai's Jev against an existing classifier eval that previously used Gemini 2.5 Flash Lite. It won both on quality (saturated the eval) and speed (6x)
Grok Bot Jev Router
A reference router and skill that put Jev in front of Grok Bot so each request is classified before expensive research, browser, retry, or subagent work, returning actions such as reuse_cache or ask_human.

Highlights
- Explicit actions include reuse_cache, stop_retry, run_deterministic, chat_only, research_capped, allow_subagent, and ask_human, with shadow and active modes.
- A kill switch disables the router through enabled: false or a bypass jev marker, and src/secrets.py reads only TYPESAFE_API_KEY from the environment.
- In a recorded local A/B across five tasks, flight browser opens fell from 1 to 0, same-approach retries from 3 to 0, and research pages from 10 to 4.
- A separate 24-candidate timing run took 53.803 s for the uncapped arm and 4.125 s for the Jev-ranked top-five arm, with two Jev calls at about $0.000405.
- It never sends, publishes, pays, deletes, or changes permissions without a human approval path, and it logs decisions without the API key.
Quickstart
bash
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
cp config.example.yaml config.yaml
export TYPESAFE_API_KEY=YOUR_API_KEY
.venv/bin/python scripts/dry_run.pyWatch out
MIT-licensed. Needs Python and a TYPESAFE_API_KEY; shadow mode enforces nothing, active mode depends on the pasted skill honoring decisions, and the A/B figures are one local run's proxy measurements.

The case against Jev-scored compaction
This is a terrible compaction strategy that fundamentally doesn't understand how compaction and context management work. Seems like a lot of people are confused so let's break this down. 1. Compaction isn't a filter The role of compaction is to clean up history to keep the Show more
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
