claude-code - 💡(How to fix) Fix Stray '>' character appears at prompt line after response completes (still occurring; refile of #34970) [1 comments, 2 participants]

TL;DR

The issue can be mitigated by investigating and potentially adjusting the handling of ANSI escapes or status line updates in the terminal configuration.

Guidance

• Review the iTerm2 terminal configuration for any custom settings that might interfere with ANSI escape sequences or status line updates.
• Verify that the session-summary.py hook is not inadvertently printing any characters to stdout, despite being intended to write to stderr only.
• Check for any updates to iTerm2 or zsh that may address issues related to ANSI escape rendering or status line updates.
• Consider temporarily disabling the status line or voice features to isolate if either contributes to the issue.

Example

No specific code snippet can be provided without more details on the session-summary.py hook or the exact iTerm2 and zsh configurations.

Notes

The issue's intermittent nature and lack of clear correlation with specific actions or content make it challenging to pinpoint the exact cause without further debugging or logging information.

Recommendation

Apply workaround: Temporarily disable the status line or adjust ANSI escape handling in the terminal configuration to see if it mitigates the issue, as the root cause seems related to these aspects.
