opencode-notifier

Why we included this project

OpenCode sessions can run for a while, and this plugin is for the stretches when you are not staring at the terminal. It fires a system notification, plus an optional sound, when the agent needs permission, finishes a generation, hits an error, or opens the question tool, so you can work in another window and still know when it actually needs you. Setup is one line in opencode.json, and the config file lets you choose which events notify, whether sounds play, and even run a custom command when an event fires. It works on macOS, Linux, and Windows, and subagent completion and cancel events stay silent by default so you are not spammed. If you multitask while agents run, this is a small, practical convenience rather than a flashy feature.
