Jev solved local harness/model routing I use a combination

The clip posted with this case (hosted by the collector’s media CDN); original post on X · 17s.

Used Jev in a Claude Code hook to route tasks to the right harness or model based on task intensity before delegation.

The original post

Jev solved local harness/model routing

I use a combination of Claude Code, Codex and Opencode as my local agentic stack and routing to other harnesses was always enforced in the system prompt/rules

With a deterministic hook that Claude Code can decide before delegation, Jev helps to route to the right harness/model based on the task, and it's pretty accurate based on the intensity/intelligence of the task

> Mechanical tasks get routed to Haiku

> Intelligent ones to Opus sub-agents

> Long-running implementation work to external harness

Where this case fits

Filed under agents & workflows, coding & developer tools. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Other posts in the same family are on the agents & workflows page.
