Automatic model+effort routing for Claude Code: tiered subagents, escalation ladder, independent verifier
README preview
# Gearbox Gearbox is a Claude Code plugin that automatically routes subagent delegations to the cheapest model tier that can handle the work — haiku for search and mechanical edits, sonnet for standard implementation, opus for hard architectural problems. It adds an escalation ladder so a cheap agent that gets stuck hands off to a more expensive one, and a verifier gate that catches gaming patterns (like reward-hacking an impossible test) before bad results are accepted. JSONL telemetry logs every delegation and its outcomes — which tier ran it, whether a named agent or a generic proxy handled it, verifier verdicts, and escalations — so you can measure how your routing actually behaves. ## Install **In your terminal:** ```bash claude ``` **Inside the Claude Code session** (slash commands — these do not work in your shell): ```text /plugin marketplace add Adityaraj0421/gearbox /plugin install gearbox@gearbox ``` **At the scope prompt, choose user (all projects). If you accept the default, Gearbox only routes in the folder you installed from.**
