Pointbreak Claude Code Plugin

Debug programs with real debuggers through Claude Code. This plugin adds the Pointbreak skill and debugging commands that enable AI-assisted debugging with breakpoints, variable inspection, and step-through execution.

🎯 What This Plugin Does

Instead of adding print statements or guessing what's wrong, Claude can now:

• Set breakpoints - "Break when x > 100"
• Inspect variables - "Show me the value of user_input"
• Step through code - "Step into this function"
• Find bugs faster - Run and examine code in real-time

📦 Installation

Prerequisites

1. Pointbreak must be installed (Installation Guide)

   • IDE extension installed (VS Code, Cursor, or compatible)
   • MCP server configured

2. Claude Code installed and running

Install the Plugin

# Add this repository as a marketplace
/plugin marketplace add withpointbreak/pointbreak-claude

# Install the plugin
/plugin install pointbreak@pointbreak-claude

Or for local development:

# Clone the repository
git clone https://github.com/withpointbreak/pointbreak-claude.git

# Add as local marketplace
/plugin marketplace add /path/to/pointbreak-claude

# Install
/plugin install pointbreak@pointbreak-claude

🚀 Quick Start

Once installed, simply ask Claude to debug:

Debug this Python script - it's not returning the right results

Claude will:

1. Analyze the code
2. Set strategic breakpoints
3. Run the debugger
4. Inspect variables
5. Identify the issue

📚 What's Included

Agent Skill

skills/pointbreak/ - Comprehensive debugging skill that teaches Claude:

• How to use all Pointbreak MCP tools effectively
• Common debugging patterns (loops, exceptions, state tracking)
• Language-specific debugging configurations
• Advanced techniques (performance, concurrency, memory)

The skill triggers automatically when Claude detects debugging needs.

Slash Commands

/debug [file-path]

Start debugging with intelligent breakpoint placement.

/debug src/app.py          # Debug specific file
/debug                      # Debug current file

Claude analyzes your code and sets breakpoints at:

• Function entry points
• Error handling blocks
• Return statements
• Loop entry points
• Conditional branches

/step [over|into|out]

Step through code execution.

/step                       # Step over (default)
/step into                  # Step into function
/step out                   # Step out of function

/inspect [variables...]

Inspect variable values at current breakpoint.

/inspect result error       # Check specific variables
/inspect user.email         # Check nested properties
/inspect                    # Show all local variables

💡 Usage Examples

Find a Bug

You: "The calculate_average function returns wrong results"

Claude will:

1. Set breakpoint in calculate_average
2. Run to breakpoint
3. Inspect variables (numbers, total, count)
4. Step through the logic
5. Identify the bug (e.g., dividing by wrong value)

Understand Code Flow

You: "Step through the authentication process"

Claude will:

1. Set breakpoint at auth function entry
2. Step into each function call
3. Show variable values at each step
4. Explain what's happening

Track Down a Crash

You: "Program crashes with IndexError on line 42"

Claude will:

1. Set breakpoint before line 42
2. Inspect array/list and index variables
3. Identify why index is out of bounds
4. Suggest the fix

🔧 Advanced Usage

Debug Configurations

The skill includes pre-configured debug setups for:

• Python (basic, Django, Flask, FastAPI, pytest)
• JavaScript/Node.js (Express, TypeScript, Jest, Next.js)
• Rust (cargo build, cargo test)
• Go (programs, tests, packages)
• C/C++ (GCC, Clang, LLDB, MSVC)
• Java, C#, Ruby, PHP, and more

Performance Debugging

You: "Why is this function so slow?"

Claude can:

• Set breakpoints at function boundaries
• Time execution between points
• Identify slow code sections
• Suggest optimizations

Async/Concurrent Debugging

You: "Debug this race condition"

Claude can:

• List all threads
• Pause all threads simultaneously
• Inspect shared state across threads
• Identify conflicting access

🛠️ How It Works

This plugin uses the Model Context Protocol (MCP) to connect Claude to your IDE's debugger through the Pointbreak MCP server.
