Python Debugger Skill

Python Debugger Plugin Marketplace

A Claude Code plugin marketplace containing the Python Debugger plugin - PyCharm-like debugging for Python scripts.

Why Use This Skill?

The Problem

When Claude Code encounters a bug in Python code, it typically resorts to:

• Adding print statements and re-running
• Reading code and guessing what's wrong
• Making changes based on assumptions without verifying them

This is inefficient. Real developers don't debug this way—they use debuggers.

The Solution

This skill gives Claude Code the same debugging capabilities that developers use in PyCharm or VS Code:

• Set breakpoints at specific lines or on exceptions
• Step through code line by line to see exactly what happens
• Inspect variables at any point during execution
• Navigate the call stack to understand how execution reached a certain point
• Evaluate expressions in the current context to test hypotheses

Why This Matters

1. **Faster bug resolution** - Instead of guessing and re-running, Claude can pause execution exactly where needed and inspect state directly.

2. **Systematic debugging** - The skill includes debugging methodology that teaches Claude to debug like an experienced developer: form hypotheses, verify assumptions, binary search for bugs.

3. **Better accuracy** - By actually observing runtime values rather than inferring them from code, Claude makes fewer mistakes when diagnosing issues.

4. **Complex bug handling** - Some bugs only manifest at runtime with specific data. Print debugging can't easily catch issues like race conditions, state mutations, or deep call stack problems. A real debugger can.

Example Scenario

**Without this skill:**

User: "This function returns wrong values sometimes"
Claude: *reads code* "I think the issue might be X. Let me add some prints..."
*adds prints, runs, reads output, guesses again*

**With this skill:**

User: "This function returns wrong values sometimes"
Claude: *set
