Claude Code v0.2.31

Custom Slash Commands

Users can now create custom slash commands by placing Markdown files in .claude/commands/ directories. These files will automatically appear as slash commands that insert prompts into your conversation.

Usage Example:

# Create a custom command file
mkdir -p .claude/commands/
echo "# My Custom Prompt\nThis is my custom prompt content" > .claude/commands/my-command.md

# In Claude Code, use the command
/my-command
# This will insert the contents of my-command.md into your conversation

This feature allows you to create reusable prompts and workflows specific to your project or personal preferences.

MCP Debug Mode

A new --mcp-debug flag provides detailed error information when MCP (Model Context Protocol) servers encounter issues.

Usage Example:

# Run Claude Code with MCP debugging enabled
claude --mcp-debug

# When MCP server errors occur, you'll see detailed error messages like:
# MCP server "server-name" Error details here

This helps troubleshoot MCP server configuration and connectivity issues.

• Enhanced Error Logging: MCP server errors are now logged with better formatting and optionally displayed to console when debug mode is enabled
• Version Update: Updated to version 0.2.31
• Sentry Environment: Error tracking now includes environment tag set to "external"

• Improved error handling in the MCP tool execution flow with better error reporting
• Reorganized import statements for Node.js process and stream modules
