[Bug]: opencode overwriting files on startup #3145

Version: v0.15.0
Change introduced: “Ensured @opencode-ai/plugin is available in .opencode folder”

Description

Since v0.15.0, every time opencode starts it automatically overwrites several key project files, including:
• package.json
• bun.lock
• .gitignore

This happens even when these files already exist and contain valid project-specific dependencies or settings.

I understand the intent might be to ensure consistency within .opencode, but in practice it’s replacing the project’s own configuration each time.

Impact

I have multiple tools and plugins that rely on custom Bun dependencies.
With this new behavior, I have to revert those file change every single time I start opencode.

Questions

1. Is this the intended behavior?
2. Should I now have a dedicated package.json inside each tool/plugin directory to prevent opencode from touching the root files?

Expected Behavior

opencode should respect existing project configuration files and only modify them when explicitly needed — not overwrite them on startup.

Environment

• opencode: v0.15.0
• Runtime: Bun
