You can also run the update script locally using Bun:

bun install
bun install opencode-ai
bun run scripts/update-json.ts

CLI — Auto-Sync to VS Code

A cross-platform CLI that syncs model definitions directly into VS Code's chatLanguageModels.json, with optional cron / scheduled task support.

Quick Start

./opencode-auto-update --sync

# Sync a specific provider + source
./opencode-auto-update --sync --provider "OpenCode Go" --source go

Or build from source:

bun install
bun run build       # → dist/opencode-auto-update (or .exe on Windows)
