switchboard

ruban-24

468

Routing & Cost Optimization Apache-2.0 E2 · source reviewed

Switchboard is a local Claude Code and Codex router. It assesses a new conversation's task with Jev, applies deterministic confidence rules to select the model and reasoning effort, and pins that route through follow-ups, tool calls, and resume to avoid unnecessary prompt-cache disruption.

JEV · Decision point

Jev classifies the task's capability tier, whether context is sufficient, and the lowest adequate reasoning effort for the candidate model. Application code applies confidence floors, maps the result to a model and effort, and persists that pair for later turns and tool continuations.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.
