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
Lahfir uses Claude Code, Codex, and Opencode as a local agentic stack. Previously, routing to other harnesses was enforced through the system prompt and rules.
