OpenCode local configuration and development gotchas

Config-time changes such as opencode.json require a user-controlled quit/restart: file watchers and tool.reload() replay active transforms but do not rerun plugin setup. Never restart production services automatically. Distinguish shekohex/opencode-pty, the removable agent plugin, from anomalyco/opencode-pty’s native daemon imported as @opencode-ai/pty, which persistent PTY support requires. For local UI work, opencode dev web is only a proxy to https://app.opencode.ai; run bun dev serve --port 4096 at the repository root and bun dev -- --port 4444 in packages/app, then open http://localhost:4444.
