OpenCode 2.2 lets plugins build into the desktop app and drops its GitHub Action

OpenCode 2.2 lets a plugin add its own panels, commands and settings pages to OpenCode Desktop. Desktop plugins are experimental, so their API can still change between releases.

Part one: desktop plugins.

A plugin package already shipped a server part and a terminal part. Now it adds a desktop part beside them, and the desktop app's own features are built as plugins on that same SDK.

Desktop plugins can now do what the built-in features do. They show toasts and ask in the app's own dialogs, notify you while OpenCode is in the background, and manage tabs and the prompt.

You manage desktop plugins in one place: Settings, then Extensions, then Plugins, next to your MCP servers and skills. Each plugin gets a switch, a Reload button, and its error when it fails to load.

Plugins sit beside MCP servers and skills

Part two: the desktop app.

The desktop app now asks how you work. Focus puts tabs across the top, with room to write prompts. Pro moves tabs down the side, compact and icon-first. Your current tab setting carries over.

Pick a Focus or a Pro layout

Hover any message to rewind or fork from it. Rewind hides that message and everything after it, puts your files back as they were, and returns your prompt to the composer, with an Undo.

Models now open in a searchable dialog with your favorites and recent picks. The todo list is back above the composer, if you opt in. And future Windows updates install in about a second.

Part three: sessions and models.

Plugins can now attach keyed instructions to a session. Each change arrives as a small update at the next step, so the prompt cache stays intact. The entries also survive compaction and reverts.

You can now choose how long the prompt cache lasts. On Anthropic it was five minutes, so an agent waiting on a slow tool paid to rewrite its whole context. Now set an hour per model.

Plugins and the SDK get experimental image generation, and a Decision API for models that answer structured questions about text or an image: a yes or no, a choice, or a score.

Sign in with ChatGPT adds GPT 6.1 Terra and Terra Fast. Compaction now sizes itself from the provider's reported token count, and throttled requests retry instead of showing up as a context overflow.

Part four: what's gone.

OpenCode no longer publishes its GitHub Action, and you should remove it from your workflows. Workflows that point at its existing tags keep working, because those tags are locked to older commits.

Plugins for OpenCode's terminal app now require OpenTUI 0.7. A plugin still built on OpenTUI 0.6 fails to install until its author moves it to the new version.

If you build on OpenCode's AI package, its root now exports the Promise API, matching the SDK and client packages. The Effect API moves to its own entry point.

On long Anthropic sessions, the setting I'd change first is a one-hour prompt cache. Before upgrading a plugin or an SDK app, read the breaking changes in OpenCode's 2.2 release notes.
