New Features

Tool Permission Modes

Added new permission modes for tool execution, giving users more control over how Claude interacts with their system:

• default - Standard mode with confirmation prompts for potentially sensitive operations
• plan - Plan mode where Claude outlines steps before executing
• acceptEdits - Automatically accepts file edits without confirmation
• bypassPermissions - Bypasses permission prompts for all tool operations

You can switch between modes during a conversation to control the level of interaction required.

PreCompact Hook

A new PreCompact hook event that runs before conversation compaction occurs. This allows custom scripts to:

• Modify custom instructions before compaction
• Block compaction by returning exit code 2
• Provide feedback to users about the compaction process

# In your hooks configuration
# Exit code 0: stdout becomes custom compact instructions
# Exit code 2: blocks compaction
# Other codes: shows stderr to user but continues
