tagline: Per-agent model fallback chains (primary/secondary/tertiary) for OpenCode v2.x with a local web UI
description: Give every OpenCode agent a primary, secondary, and tertiary model chain, managed from a clean local web UI served by the plugin itself. The model picker mirrors the models you enabled in Settings > Models, provider-qualified refs make the same model on two different providers count as separate fallback steps, and chains are written natively into oh-my-opencode-slim (agents.<agent>.model arrays) or plain OpenCode config with automatic backups. Zero dependencies; the web UI binds to 127.0.0.1 only. Built for OpenCode v2.x — uses the OpenCode V2 plugin API.
