OpenCode 1 and 2

OpenCode 2 replaced the plugin API: a plugin written for OpenCode 1 does not run on it. From 0.6.0, Cockpit ships one package for both — each entry carries a v1 half and a v2 half, and whichever OpenCode loads it picks its own. Nothing to choose at install time.

Which Cockpit for which OpenCode

Your OpenCode	Cockpit
2.0.15 or newer	0.6.0 or newer	everything, with the differences below
1.18.x	0.6.0 or newer	everything — tested on 1.18.0, 1.18.28 and 1.18.32
older than 1.18	not supported	upgrade OpenCode — 1.17 loads the panels but never draws full screen

opencode --version says which you have.

Installing on OpenCode 2

opencode plugin add opencode-cockpit@0.6.0

That writes "plugins" in opencode.json, and OpenCode 2 loads both halves from there — the agent tools and the interface. A single bay works the same way:

opencode plugin add @opencode-cockpit/shell@0.6.0

Options go in the entry as an object — the v2 spelling of v1’s [name, options] pair:

~/.config/opencode/opencode.json

{
  "plugins": [
    { "package": "opencode-cockpit@0.6.0", "options": { "features": { "status": false } } }
  ]
}

Moving from OpenCode 1 to 2

Nothing to change. OpenCode 2 reads an existing v1 opencode.json — "plugin" and all — and copies a global tui.json into its own cli.json on first start. Cockpit’s own settings (~/.config/opencode-cockpit/config.json, .cockpit.json) and your statusline modules are the same files on both.

What does not carry over is Cockpit before 0.6: it runs on OpenCode 1 only. If OpenCode 2 lists Cockpit under /plugins as failed, change the version in your opencode.json entry to the newest release and restart. Edit that entry rather than running opencode plugin add beside it — add writes a second one and leaves the old.

Running both side by side

The two can share one machine and one config. Install OpenCode 1 under another name (it is the opencode-ai package on npm), and point both at the same Cockpit:

mkdir -p ~/.opencode-v1 && cd ~/.opencode-v1 && npm i opencode-ai@1.18.32
# then run it as ~/.opencode-v1/node_modules/.bin/opencode, or alias it

What differs on OpenCode 2

Everything Cockpit does works on both. Where OpenCode 2 gives a plugin less to work with, this is what you will notice:

	OpenCode 1	OpenCode 2
shell_start permission	asks with your bash permission rules	runs without asking — v2 gives a plugin tool no way to ask
Tool calls in the chat	shell_start, review_list…	execute, calling them in Code Mode — same tools, same results
Updating	/plugins-update, or npx opencode-cockpit@latest update	change the version in opencode.json; Cockpit’s updater edits OpenCode 1’s files only
Statusline lsp segment	language servers	empty — v2 does not expose them to plugins
Colours	the theme	the same theme, except the subtle border grey, one shade lighter

The permission difference

On OpenCode 1, an agent starting a background shell asks first unless your rules allow it. On OpenCode 2 it does not. If you rely on bash permission rules to keep an agent from running commands, know that shell_start is not held by them there.

We are working on this: finding how a plugin tool can ask on OpenCode 2 — its tools accept a permission setting that is not documented yet — so shell_start respects your bash rules there the way it does on OpenCode 1.

These track what OpenCode 2 exposes; each is revisited as it grows.
