Claude Code v1.0.27

# Claude Code v1.0.27 Changelog

• Enhanced directory addition feedback: The /add-dir command now provides more detailed and specific error messages when adding working directories
• Clear message when no path is provided: "Please provide a directory path."
• Specific error when path doesn't exist: "Path [path] was not found."
• Helpful suggestion for non-directory paths: "[path] is not a directory. Did you mean to add the parent directory [parent]?"
• Informative message for already accessible directories: "[path] is already accessible within the existing working directory [existing]."
• Success confirmation: "Added [path] as a working directory."

• Additional directories from configuration: Claude Code now reads additional working directories from the configuration file
• Directories specified in permissions.additionalDirectories are automatically added at startup
• These are processed alongside command-line --add-dir arguments

• Fixed unnecessary API calls: Terminal title generation now skips processing for local command output (messages starting with <local-command-stdout>)
• Disabled prompt caching: Changed enablePromptCaching from true to false for terminal title requests to improve performance

• Replaced direct stream import with PassThrough from stream
• Changed from node:process import to specific cwd import from node:process
• Removed unused path.resolve import

• Refactored directory addition logic to use a result-based pattern instead of direct success/message returns
• Improved error handling and message formatting for directory operations
• Better separation of concerns between directory validation and permission context updates

# File instead of directory
claude --add-dir /etc/passwd
