🐞 Bug Report: VSCode IDE integration fails with /ide — “No available IDEs detected”

✅ Platform

• [x] Other: Claude Code VSCode Extension (local)

✅ Claude CLI version:

claude version 1.0.31

✅ Operating System:

macOS Sequoia 15.5 (Apple Silicon)

✅ Terminal:

🔍 Bug Description

When running the /ide command from the Claude Code CLI, I receive the following error message:

No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running.

Even though:

• The Claude Code extension is installed and active in VSCode
• VSCode is running with the same project folder open
• No firewall, VPN, or port restrictions are present

The CLI is still unable to detect the IDE.

🧪 Steps to Reproduce

1. Launch VSCode and ensure the Claude Code extension is installed and enabled
2. Open a terminal in the same project directory
3. Run claude to start the Claude CLI
4. Enter /ide
5. Observe the error message

---

✅ Expected Behavior

Claude CLI should detect the running VSCode instance and connect automatically, enabling integrated features like file navigation, code highlighting, and context sharing.

---

❌ Actual Behavior

The CLI fails to detect any IDE, blocking access to the /ide feature.

📎 Additional Context

• No proxy or VPN in use
• VSCode CLI (code) is available in the shell
• Claude Code VSCode extension version: v0.1.3 (please verify actual version)
• Tried restarting VSCode and the terminal — no effect
