Can I set conditional breakpoints with this skill?

Yes, you can set line-based breakpoints with specific conditions (e.g., x > 10) so the debugger only pauses when that logic evaluates to true.

Can I inspect local variables mid-execution?

Absolutely. You can view all local and global variables at the current execution point or use the eval command to check the value of specific expressions.

Can I navigate the call stack?

Yes, the skill provides commands to move up and down the call stack, allowing you to inspect the context of caller functions and understand how a specific code path was reached.

Does it support exception debugging?

Yes, you can configure the debugger to break on specific exception types like ValueError or use a wildcard to catch any unhandled exception automatically.

How does this enhance Claude's coding abilities?

It allows Claude to interact with a live runtime, enabling it to 'see' variable states and execution flow that are invisible during static code analysis, leading to more accurate bug fixes.

Developer Tools

Debug Python scripts with PyCharm-like capabilities including breakpoints, stack navigation, and variable inspection.

The Python Debugging skill empowers Claude to perform deep diagnostic tasks on Python scripts through a specialized CLI interface. It enables setting line-based, conditional, and exception breakpoints, stepping through execution flow, and inspecting local or global variables in real-time. By providing a structured debugging methodology and decision framework, this skill helps developers identify the root cause of crashes, logic errors, and unexpected behaviors systematically rather than through trial and error, making Claude a much more effective pair-programmer during troubleshooting sessions.
