What's Wrong?

IDE integrations not detected when running Claude via custom HOME path alias

Description

I use two Claude accounts:

• Personal account → default CLAUDE_CONFIG_DIR
• Company account → custom CLAUDE_CONFIG_DIR path

To switch between them, I’ve created a shell alias that runs claude with a custom CLAUDE_CONFIG_DIR path for the company account.

alias claudework="CLAUDE_CONFIG_DIR=~/.claudework claude"

Issue

When running Claude via the aliased command (with the custom CLAUDE_CONFIG_DIR path), IDE integrations are not detected in IntelliJ IDEA.
However, when running the default claude command (using the default CLAUDE_CONFIG_DIR), IntelliJ IDEA integration works perfectly.

Actual behavior

IDE integrations are only detected when using the default CLAUDE_CONFIG_DIR. They are missing when Claude is launched via the alias with a custom CLAUDE_CONFIG_DIR.

Happy to provide more details or debug logs if needed.

What Should Happen?

IDE integrations (IntelliJ IDEA) should be detected regardless of whether Claude is launched with a custom CLAUDE_CONFIG_DIR path.

Error Messages/Logs

Steps to Reproduce

• Install Claude CLI.
• Verify that IntelliJ IDEA detects the Claude IDE integration when running
• Create a custom home directory for a second (company) Claude account:
• Create a shell alias to run Claude with a custom HOME path. Authenticate Claude using the aliased command:

``bash
mkdir -p ~/.claude-work
alias claude-work='CLAUDE_CONFIG_DIR=~/.claude-work claude'
claude-work
``

• Open IntelliJ IDEA with the Claude IDE integration enabled.
• Attempt to use Claude from IntelliJ IDEA or check the integration status.
• Observe that IntelliJ IDEA does not detect the Claude integration when using the custom CLAUDE_CONFIG_DIR.
• Run Claude using the default command
• Observe that IntelliJ IDEA integration works correctly when using the default CLAUDE_CONFIG_DIR.

Additional Information

Notes / Suspicions

• Claude may be resolving IDE integration configs, sockets, or cache paths relative to the default CLAUDE_CONFIG_DIR
• Custom CLAUDE_CONFIG_DIR paths might not be fully supported or documented for IDE detection
