## Changes

### New Features

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.

### Internal Improvements

- **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"

### Technical Changes

- Improved error handling in the MCP tool execution flow with better error reporting
- Reorganized import statements for Node.js process and stream modules
- Added user/project scope variables for command organization
