Web UI does not open automatically when Plannotator Code Review is triggered

[ZoeImport]

Description

When triggering the Plannotator Code Review, the console shows:

The Plannotator Code Review has been triggered. Opening the review UI...
Acknowledge "Opening code review..." and wait for the user's feedback.

However, the web UI browser does not open automatically.

Environment

• OS: Linux
• Node version: v22.14.0
• npm version: 10.9.2
• open-plan-annotator version: 1.2.1
• opencode: installed globally

Steps to reproduce

1. Install: curl -fsSL https://plannotator.ai/install.sh | bash
2. Add to opencode.json config: "plugin": ["@plannotator/opencode@latest"]
3. Restart opencode and trigger Plannotator Code Review

Expected behavior

Web UI browser should open automatically.

Actual behavior

Message appears in console but browser does not open.

Additional context

The plugin seems to trigger correctly but the URL opening mechanism may not be working on Linux environments.

@ZoeImport can you help me debug:

1. in a seperate terminal, after running /plannotator-review, can you run:

plannotator sessions # (outside of opencode)

Do you see the url here?

2. Separately - just run isolated in terminal:

plannotator review

I want to see if there is an error?

Does plugin use xdg-open? I have try

➜ ~ xdg-open "https://google.com"

Opening in existing browser session.

➜ ~ echo $DISPLAY

:1

➜ ~ xdg-settings get default-web-browser

google-chrome.desktop

➜ ~ xdg-mime query default x-scheme-handler/http

google-chrome.desktop

➜ ~ xdg-mime query default x-scheme-handler/https

OpenCode spawns the plugin in a child process context where those env vars may not propagate, so xdg-open fails silently

(i think)
