What's Wrong?

## Description
The Claude Code CLI enters an uncontrollable infinite loop where it automatically and repeatedly sends the /rate-limit-options command without any user input. This completely blocks normal usage and makes the tool unusable.

## Severity
Critical - Complete system failure, tool becomes completely unusable

## Steps to Reproduce

1. Use Claude Code CLI for extended coding session
2. Perform multiple file edits and error fixes
3. At some point, the CLI starts auto-sending /rate-limit-options repeatedly
4. No user action can stop the loop (typing, commands, etc.)
5. Only force-killing the process stops the behavior

## Expected Behavior

• /rate-limit-options should only execute when user explicitly types it
• CLI should respond to user input normally
• System should not enter infinite loops

## Actual Behavior

• System automatically sends /rate-limit-options every few seconds
• User cannot interact with the CLI
• No way to stop without force-killing the process
• Pattern: /rate-limit-options appears 2 times per iteration

## Environment

• OS: macOS Darwin 24.6.0
• Claude Code Version: [Your version]
• Working Directory: /Users/impharaonjin/app/trader
• Git Repo: Yes
• Context: After ~90,000 tokens of conversation involving multiple file edits

## Impact

• User Productivity: Complete blockage - cannot continue work
• Data Safety: All work before the loop is saved, but current session lost
• Workaround Required: Force quit and restart CLI

## Reproduction Frequency
Occurred once during extended session. Unable to reproduce on restart.

## Additional Context

• Issue appeared after completing multiple code fixes
• Session involved heavy file editing (5+ files modified)
• Loop started after changelog.md update
• User was NOT typing /rate-limit-options - system generated it automatically

## Logs/Screenshots
[If you have any screenshots or log files, attach them here]

## Temporary Workaround

1. Force kill the CLI process: pkill -9 claude
2. Restart Claude Code
3. Previous work is preserved in files

## Request
Please investigate what triggers this infinite loop and add safeguards to prevent it. This is a critical bug that makes the tool completely unusable when it occurs.
