Bug Report: Plugins fail to load on Windows

Environment

• OS: Windows 10 (Build 26200.7922)
• Claude Code version: 2.1.62
• Plugins: financial-analysis@financial-services-plugins, wealth-management@financial-services-plugins

Steps to Reproduce

1. claude plugin marketplace add anthropics/financial-services-plugins
2. claude plugin install financial-analysis@financial-services-plugins
3. claude plugin install wealth-management@financial-services-plugins
4. claude plugin list

Expected Behavior
Plugins install and load successfully with status active.

Actual Behavior
Both plugins show Status: × failed to load with the following error:

Hook load failed: [
  {
    "expected": "object",
    "code": "invalid_type",
    "path": [],
    "message": "Invalid input: expected object, received array"
  }
]

Additionally, after restarting Claude Code, the plugins are no longer listed — they appear to be automatically uninstalled when they fail to load.

Additional Notes
Installation itself reports success (√ Successfully installed plugin), so the issue appears to be in the plugin manifest validation at load time, not during install. The error suggests a schema mismatch — somewhere an array is being passed where an object is expected, possibly in plugin.json.
