New Features

Plan Mode

• New planning mode for complex tasks: Claude can now work in "Plan Mode" where it will research and present a plan before making any changes to your codebase
• Exit plan mode tool: When in plan mode, Claude will use the ExitPlanMode tool to present the completed plan and prompt you to confirm before proceeding with implementation
• Visual indicators: Plan mode has its own color scheme in the UI (cyan/teal colors) to clearly indicate when this mode is active
• Usage: Plan mode is automatically triggered for tasks that require planning and research before implementation. Claude will not make any file edits or run any commands that modify system state while in plan mode

Improved Task Management

• Enhanced todo list guidance: Claude now has better heuristics for when to use the todo list tool:
• Complex multi-step tasks (3 or more distinct steps)
• Non-trivial tasks requiring careful planning
• When users explicitly request a todo list
• When users provide multiple tasks (numbered or comma-separated)
• Better task tracking: Claude is now instructed to mark tasks as completed immediately after finishing them, not batching completions
