claude-code - 💡(How to fix) Fix GUI SSH "Add connection" feature — remote ccd-cli helper crashes with exit 1 during initialize on [1 comments, 2 participants]

• Running ccd-cli/2.1.111 directly with --print --output-format=stream-json without --verbose returns: Error: the helper supports, OR surface a clear version-mismatch error instead of "exit code 1".

TL;DR

The issue can be worked around by using SSH and running the claude command in the Terminal instead of through the GUI's "New SSH connection" flow.

Guidance

• The error message suggests that the GUI may not be passing the --verbose flag correctly, or the helper binary is out of sync with what the GUI expects.
• The fact that running with --verbose injected still exits with code 1 implies that the issue may be related to the claude-opus-4-7[1m] model ID syntax, which may not be supported by the helper version 2.1.111.
• To mitigate the issue, the GUI should either download a helper version that matches the flags it sends, or degrade to flags the helper supports, or surface a clear version-mismatch error.
• The workaround of using SSH and running the claude command in the Terminal works, suggesting that the issue is specific to the GUI's "New SSH connection" flow.

Example

No code snippet is provided as it is not clearly supported by the issue.

Notes

The issue may be related to a version mismatch between the GUI and the helper binary, or a syntax issue with the model ID. The workaround provides a temporary solution, but a more permanent fix would require addressing the underlying issue.

Recommendation

Apply workaround: using SSH and running the claude command in the Terminal instead of through the GUI's "New SSH connection" flow, as it provides a reliable alternative until the underlying issue is resolved.
