User Experience Improvements

Command Processing

• Enhanced Slash Command Parsing: Improved parsing of slash commands with better argument extraction and MCP command recognition.

  # Regular command
  /search keyword
  
  # MCP command (automatically detected)
  /tool-name (MCP) arguments

• User Prompt Submit Hooks: Added support for hooks that can intercept and modify user prompts before they're sent to Claude. Hooks can:
• Block prompts with error messages
• Add additional context to prompts
• Run preprocessing steps

Error Handling

• AWS Credential Errors: Better error messages and automatic retry mechanisms for AWS authentication failures.
• Hook Error Display: Clear error messages when prompt submission is blocked by hooks.
