Plugin marketplace schema validation errors on v2.1.58

[laowuisme]

Description

Installing plugins from the official marketplace (claude-plugins-official) and third-party marketplaces fails with schema validation errors on Claude Code v2.1.58.

Steps to Reproduce

1. Run /plugin install superpowers@claude-plugins-official
2. Or add a marketplace and install: /plugin marketplace add obra/superpowers-marketplace then /plugin install superpowers@superpowers-marketplace

Error Output

Invalid schema: plugins.56.source: Invalid input, plugins.63.source: Invalid input, plugins.67.source: Invalid input, plugins.71.source: Invalid input, plugins.72.source: Invalid input, plugins.73.source: Invalid input, plugins.74.source: Invalid input, plugins.75.source: Invalid input

When the marketplace is removed and reinstalled, the error persists:

Failed to load all marketplaces. Errors: claude-plugins-official: Invalid schema: plugins.56.source: Invalid input, plugins.63.source: Invalid input, plugins.67.source: Invalid input, plugins.71.source: Invalid input, plugins.72.source: Invalid input, plugins.73.source: Invalid input, plugins.74.source: Invalid input, plugins.75.source: Invalid input

Expected Behavior

Plugins should install successfully from both official and third-party marketplaces.

Environment

• Claude Code version: 2.1.58 (latest stable)
• OS: macOS (Darwin 25.3.0)
• Installation method: Standalone installer (~/.local/share/claude/versions/)

Notes

The errors reference specific plugin indices (56, 63, 67, 71-75) with invalid source fields, suggesting the marketplace plugin definitions use a source format not yet supported by the current schema validator in v2.1.58.
