Claude Router
Use Jev to select a Claude model and effort for each new coding turn.
Added to Jevfast
How it uses Jev
With Jev as the active classifier, the router sends the new request and recent dialogue. Jev returns route, continuation and optional activity decisions. Local policy maps this advice to a Claude model and effort while Claude Code keeps execution and provider traffic.

App workflow
- Collect context
The hook gathers the current prompt and recent dialogue for the active classifier.
- Classify
Ask Jev for route and continuation, plus activity when enabled.
- Apply policy
Map the advice to configured model and effort routes; periodically reassess when configured.
- Execute
Claude Code sends provider requests, streams responses, runs tools and reports usage.
Why it is interesting
The router separates required reasoning depth from the work the turn must produce. Local policy can combine those judgments and reassess long-running work without proxying Claude model requests.
