Bug Description

Plugins installed from third-party marketplaces (non-official) don't appear in the /plugin list command output, even though they are correctly installed and registered in installed_plugins.json.

Steps to Reproduce

Add a third-party marketplace (e.g., claude-code-workflows from wshobson/agents)
Install a plugin from that marketplace: /plugin install git-pr-workflows@claude-code-workflows
Run /plugin or /plugin list to view installed plugins
The plugin doesn't appear in the list
Try to install again: /plugin install git-pr-workflows@claude-code-workflows
Get message: "Plugin 'git-pr-workflows@claude-code-workflows' is already installed"

Expected Behavior

All installed plugins should appear in the /plugin list, regardless of which marketplace they came from.

Actual Behavior

The install command correctly recognizes the plugin is already installed
The plugin files exist in ~/.claude/plugins/cache/
The plugin is registered in ~/.claude/plugins/installed_plugins.json
But the list command shows nothing (or only official plugins)

Environment

OS: Windows 11
Claude Code Version: Latest (as of 2025-01-07)

Additional Context

The installed_plugins.json shows plugins with "isLocal": true flag. This might be causing the filtering issue:

"git-pr-workflows@claude-code-workflows": [
  {
    "scope": "user",
    "installPath": "C:\Users\Omar\.claude\plugins\cache\claude-code-workflows\git-pr-workflows\1.2.1",
    "version": "1.2.1",
    "installedAt": "2026-01-03T15:52:03.936Z",
    "lastUpdated": "2026-01-03T15:52:03.936Z",
    "isLocal": true
  }
]

The known_marketplaces.json correctly shows both marketplaces:

claude-plugins-official (from anthropics/claude-plugins-official)
claude-code-workflows (from wshobson/agents)

Update: Plugins Not Loading (More Severe Than Display Bug)

After testing, the plugins from third-party marketplaces are not functional - they fail to load entirely, not just display.

Test Results

Attempted to invoke skills provided by the installed plugin:

/git-workflow --no-push
→ Error: Unknown skill: git-workflow

/git-pr-workflows:git-workflow  
→ Error: Unknown skill: git-pr-workflows:git-workflow

/pr-enhance
→ Error: Unknown skill: pr-enhance

Plugin Structure Verified

The plugin files are correctly installed:

~/.claude/plugins/cache/claude-code-workflows/git-pr-workflows/1.2.1/
├── agents/
│   └── code-reviewer.md
└── commands/
    ├── git-workflow.md
    ├── onboard.md
    └── pr-enhance.md

Summary

✅ Plugin files exist on disk
✅ Plugin registered in installed_plugins.json
✅ Install command recognizes plugin as installed
❌ Plugin doesn't appear in /plugin list
❌ Plugin skills/commands are not loaded and cannot be invoked

This suggests Claude Code is not loading plugins from third-party marketplaces at runtime, making them completely non-functional.

I'm getting this with ralph-wiggum on latest as well which is an official plugin.

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

I also already have it installed, but its errored out with the same doesn't exist message in Claude Code's plugin interface.

I'm suspecting the settings.json file for claude (on a user level) I recreated it with the same content expect with more permissions, and then this bug started to show

Same workaround applies: use a SessionStart hook with type: command to inject plugin discovery context at session start.

Example: https://github.com/yzavyas/claude-1337/blob/main/plugins/core-1337/hooks/session-start.sh

We've spent considerable time troubleshooting this with multiple structure variations, and the marketplace successfully adds every time, but plugins are never discoverable.

We tried

Relative path source ("source": "./plugins/dequelabs")

Result: Marketplace adds successfully, plugin not found

External GitHub source

"source": {
"source": "github",
"repo": "dequelabs/dequelabs-claude-plugin"
}

Result: marketplace adds successfully but plugin still not found

Different plugin naming

Tried matching marketplace name ("dequelabs")
Tried different name to avoid conflicts ("dequelabs-plugin")
Result: No difference

Verified plugin structure matches official marketplace

Compared with code-review plugin from official marketplace
Structure and file formats match
Result: Still not discoverable

attaching the final version with full code to help with debugging

There were 2 installations for claude code on my machine and one of them had that bug. I removed both and installed the latest version and then everything worked as expected
