[BUG] Skills from ~/.claude/skills/ and plugins not shown in Customize -> Skills panel

What's Wrong?

Skills installed via ~/.claude/skills/ and plugins are functional in Claude Desktop's Code tab — they appear in the / slash menu and trigger correctly. However, the Customize -> Skills panel in Claude Desktop
doesn't list them, making it appear as if no skills are installed.

• Environment: Claude Desktop (macOS), Claude Code CLI alongside
• Skills installed in ~/.claude/skills/ (5 skills via symlinks) and via plugins (specsmith, datasmith-pg, etc.)
• Slash menu correctly enumerates all skills
• Skills trigger correctly during conversations
• Customize -> Skills panel shows nothing

What Should Happen?

Skills installed via ~/.claude/skills/ should be listed in Customize -> Skills panel in Claude Desktop
