Description

When a local plugin file has a syntax error (e.g., unterminated string literal), OpenCode renders a completely black/blank screen on startup with no error message or indication of what went wrong.

The error is logged to ~/.local/share/opencode/log/:

ERROR service=default e={"name":"BuildMessage","position":{"lineText":"  hebrew: [Carmit'],",
"file":"...notifications.ts","line":5,"column":18},"message":"Unterminated string literal","level":"error"} exception

...but nothing is shown to the user in the TUI. The only way to diagnose it is to know the log file location and check manually.

Expected: OpenCode should either display an error message in the TUI (e.g., "Failed to load plugin notifications.ts: Unterminated string literal at line 5"), or gracefully skip the broken plugin and continue loading.

Related: #12192 (same black screen symptom from a different plugin), #12931 (plugin runtime errors corrupting TUI — different phase).

Plugins

Custom local plugin at ~/.config/opencode/plugin/notifications.ts (with a syntax error)

OpenCode version

v1.1.65

Steps to reproduce

1. Create a plugin file at ~/.config/opencode/plugin/example.ts with a syntax error, e.g.:

   import type { Plugin } from "@opencode-ai/plugin";
   const foo = [bar'];  // missing opening quote
   export const ExamplePlugin: Plugin = async ({ client, $ }) => ({});

2. Launch opencode
3. Observe: black/blank screen, no error message, fully unusable
4. Remove the plugin file — OpenCode starts normally again

N/A — it's a completely black screen, there's nothing to screenshot
