What's Wrong?

Environment:

• OS: Linux (WSL2)
• PhpStorm version: [Please fill in your version]
• Claude Code CLI version: [Please fill in if known]

Issue:
The PhpStorm Claude integration successfully launches Claude Code CLI in a terminal when clicking the Claude icon, but code selection detection is not working.
When highlighting/selecting code in the PhpStorm editor and interacting with Claude, the selected code is not automatically passed to Claude.

Steps to Reproduce:

Expected Behavior:
Claude should automatically detect and receive the selected code from PhpStorm editor.

Actual Behavior:
Claude Code CLI launches but has no visibility into selected code in PhpStorm. User must manually copy/paste code or provide file paths.

Additional Context:

• Terminal integration works (CLI launches successfully)
• PhpStorm button becomes grey/inactive after launching (may be expected behavior)
• User received initial toast message about Claude not starting, but CLI did launch

What Should Happen?

Claude should automatically detect and receive the selected code from PhpStorm editor.
