[BUG] Recurring "Request interrupted by user" errors during normal operations

What's Wrong?

Over the past week, I've been experiencing recurring "Request interrupted by user" errors during normal Claude Code operations. These interruptions occur randomly without any manual cancellation or action on my part.

The error message appears mid-operation, causing tasks to fail unexpectedly. This happens:

• During information retrieval operations
• When Claude Code is processing requests
• While executing routine tasks

Based on my research, this appears to be a known issue in the Claude Code infrastructure rather than a local environment problem. Similar reports exist in GitHub issues where users experience these interruptions without triggering them manually.

The error message reads: [Request interrupted by user] or [Request interrupted by user for tool use], even though no interruption was initiated by me.

What Should Happen?

Claude Code operations should complete without interruption when no manual cancellation is performed. The system should:

1. Process information retrieval requests fully without premature termination
2. Complete routine tasks without displaying "Request interrupted by user" errors
3. Maintain stable connections throughout operations
4. Only show interruption messages when the user actually cancels an operation

Operations should run to completion unless explicitly stopped by the user through an actual cancellation action (Ctrl+C, closing terminal, etc.).

Error Messages/Logs

[Request interrupted by user]
[Request interrupted by user for tool use]

The error appears randomly during operations without any stack trace or additional context. The interruption happens mid-operation and causes the current task to fail.

Steps to Reproduce

The issue occurs randomly and is difficult to reproduce consistently, but typically happens in the following scenarios:

1. Start a Claude Code session
2. Request information retrieval or any routine operation (e.g., "חפש לי מידע על..." / "search for information about...")
3. Claude Code begins processing the request
4. Mid-operation (typically within a few seconds to a minute), the error "[Request interrupted by user]" appears
5. The operation fails without completing

Frequency: This has been occurring multiple times over the past week during normal usage, without any pattern related to:

• Specific commands or operations
• Network conditions
• Time of day
• System load

Note: The issue is not triggered by any user action (Ctrl+C, closing terminal, etc.). The terminal remains open and stable throughout.

Additional Information

Additional Context:

• User location: Israel (Tel Aviv)
• Network: Stable internet connection, no VPN
• The issue has been persistent for approximately one week (as of January 28, 2026)
• No correlation found with specific operations, network changes, or system load
• Similar issues have been reported in GitHub issues by other users experiencing the same error without triggering manual cancellation

Research findings:
Based on web research, this appears to be a known infrastructure/SDK issue where the Claude Code system injects the interruption message even when no user action occurred. Other users have reported similar experiences with random terminations showing [Request interrupted by user] messages.
