1. Error appears immediately — marketplace fails to load

TL;DR

Update the Claude Code schema validator to accept the new source object format used in the official marketplace.json file on GitHub.

Guidance

• The error occurs because the Claude Code schema validator expects the source field to be a plain string, but the new marketplace.json file uses a source object with url and sha properties.
• To fix this, the schema validator needs to be updated to accept the new format, which could involve changing the validation rules to allow for an object with url and sha properties.
• As a temporary workaround, it might be possible to manually edit the cached marketplace.json file to use the old format, but this would likely be overridden when the file is re-downloaded from GitHub.
• The fact that plugin installation via direct command still works suggests that the issue is specific to the marketplace browser and its schema validation.

Example

No code snippet is provided as the issue is related to the schema validation and not a specific code block.

Notes

The issue is a regression, meaning it worked in a previous version, and updating to the latest version (2.1.117) did not resolve the issue. The problem is likely specific to the Claude Code schema validator and its interaction with the new marketplace.json file format.

Recommendation

Apply a workaround by manually editing the schema validation rules to accept the new format, as updating to a fixed version is not currently possible. This is because the latest version (2.1.117) does not resolve the issue, and there is no indication of a newer version that fixes the problem.
