[Bug]: Plugin fails to load on OpenCode 1.3.17 — missing "main" field in package.json

[tongsh6]

Description

opencode-gemini-auth@1.4.9 cannot be loaded by OpenCode v1.3.8+ because its package.json does not declare a main (or exports["./server"] / oc-plugin) field.

OpenCode's plugin loader (since v1.3.8, see anomalyco/opencode#20139) requires at least one of:

• "main" pointing to the entrypoint
• "exports": { "./server": "..." }
• "oc-plugin": ["server"]

The current package.json only has "module": "index.ts" (Bun convention), which is not recognized.

Error

Running opencode plugin -g opencode-gemini-auth:

"opencode-gemini-auth" does not expose plugin entrypoints in package.json

Expected one of: exports["./tui"], exports["./server"], package.json main for server, or package.json["oc-themes"] for tui themes.

At runtime, the plugin is silently skipped — Google does not appear as an OAuth provider.

Suggested Fix

Add a main field to package.json:

{
  "main": "./index.ts",
  "module": "index.ts"
}

This is consistent with how other working plugins (e.g., oh-my-opencode@3.15.3) expose their entrypoints.

Environment

• macOS Apple Silicon (arm64)
• OpenCode: 1.3.17
• opencode-gemini-auth: 1.4.9
• Plugin installed via: opencode plugin -g opencode-gemini-auth (no proxy)
