What's Wrong?

Steps to Reproduce:

When attempting to install a plugin from a marketplace on macOS, the installer
looks for the source path using /home/username/ instead of the correct macOS home
directory /Users/username/.

Error Message:

Error: Failed to install: Source path does not exist: /home/username/.claude/plugins/m
arketplaces/claude-plugins-official/external_plugins/context7

### Expected Behavior:

The path should resolve to:
/Users/username/.claude/plugins/marketplaces/claude-plugins-official/external_plugins/
context7

Actual Behavior:

The installer uses Linux-style home path /home/username/ instead of macOS-style
/Users/username/.

Environment:

• OS: macOS (Darwin 24.6.0)
• Claude Code version: 2.1.7
• Shell: zsh

Verification:

The plugin files exist at the correct macOS path:
$ find ~/.claude/plugins/marketplaces -name "context7" -type d
/Users/username/.claude/plugins/marketplaces/claude-plugins-official/external_plugins/
context7

Workaround:

Creating a symlink from the incorrect path to the correct one allows installation
to proceed:
sudo mkdir -p /home/username/.claude/plugins/marketplaces
sudo ln -s /Users/username/.claude/plugins/marketplaces/claude-plugins-official
/home/username/.claude/plugins/marketplaces/claude-plugins-official

What Should Happen?

The path should resolve to:
/Users/username/.claude/plugins/marketplaces/claude-plugins-official/external_plugins/
context7
