What's Wrong?

Actual: /doctor flags it as a leftover npm install and suggests an ineffective fix.

This is a false positive. The binary at ~/.local/bin/claude is a symlink to
~/.local/share/claude/versions/<version> — the standalone (non-npm) Claude Code installer.
The npm global package is not installed (npm list -g @anthropic-ai/claude-code returns
empty), so the suggested fix does nothing and the warning persists on every /doctor run.

Environment:

• Platform: Linux (Debian 6.1.0)
• Install method: standalone installer
• Claude version: 2.1.162

---

What Should Happen?

Expected: No warning, or a warning that correctly identifies this as the active standalone
installation.
