Schema validation errors for multiple plugins (56, 63, 67, 71-75)

[harrylowkey]

Description

When attempting to add this marketplace to Claude Code using anthropics/claude-plugins-official, schema validation fails for multiple plugins due to invalid source field values.

Error Message

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

Affected Plugins

The following plugin indices have invalid source fields:

• Plugin 56
• Plugin 63
• Plugin 67
• Plugin 71
• Plugin 72
• Plugin 73
• Plugin 74
• Plugin 75

Steps to Reproduce

1. Open Claude Code
2. Navigate to "Add Marketplace"
3. Enter anthropics/claude-plugins-official
4. Observe schema validation errors

Expected Behavior

All plugins in the official marketplace should pass schema validation and the marketplace should be added successfully.

Environment

• Date: 2026-03-16
• Platform: macOS (Darwin 25.1.0)

Suggested Fix

Please review the source field values for the affected plugins and ensure they conform to the expected schema format.

I'm experiencing the same schema validation error when adding anthropics/claude-plugins-official as a marketplace. Additionally, attempting to install individual plugins via CLI also fails as a result:

claude plugin install superpowers@claude-plugins-official
Installing plugin "superpowers@claude-plugins-official"...
✘ Failed to install plugin "superpowers@claude-plugins-official": Plugin "superpowers" not found in marketplace "claude-plugins-official"

It seems the invalid source fields on plugins 56, 63, 67, 71–75 prevent the marketplace from loading correctly, which cascades into all plugin installs failing. Looking forward to a fix!

@NarawitC Maybe the problem is because of the outdate version, after upgrading my claude-cli, the claude-plutins-official is already installed in the marketplace and I can search an install plugin immidiately, you should try it

I use version 2.1.58 (stable). Even after upgrading to 2.1.76 (latest), I still get the same error. I don't have the anthropics/claude-plugins-official marketplace yet, so I think the command I ran needs to install the marketplace first — but it errors out before doing so.

i use version 2.1.58(stable version). Even I change to 2.1.76(lastest version) it still same error.

Let's try, I upgrade to the latest(v2.2.76) and restart the Claude and it works.
Maybe there are some breaking changes that older versions don't support it, so for now I think we should make it work for us first

It still doesn't work even after upgrading. Both methods fail:

claude plugin install superpowers@claude-plugins-official

✘ Failed to install plugin "superpowers@claude-plugins-official": Plugin "superpowers" not found in marketplace "claude-plugins-official"

/plugin install superpowers@claude-plugins-official

Plugin "superpowers" not found in any marketplace

I'm on v2.1.58 (stable). Even after upgrading to v2.1.76 (latest), the error persists. I can add the marketplace now, but plugin installation still fails.

after upgrading, you can go to `/plugin` and search for the `superpowers` plugin manually to install it, let try this way

claude plugin install superpowers@claude-plugins-official

No, I can't. I think upgrading Claude Code to the latest version is what allowed me to add the claude-plugins-official marketplace — after that, everything works. Thanks!
