What problem does it solve?
Quickly interpret Python tracebacks and runtime failures to find the root cause, produce a minimal reproduction, and provide targeted fixes so developers can restore correct behavior with confidence.
Core Features & Use Cases
- Traceback analysis: Read and explain stack traces, identify the exact failing line and call chain.
- Reproduction & isolation: Guide creation of minimal test cases that reliably reproduce errors.
- Root cause patterns: Diagnose common causes such as None values, type mismatches, mutable defaults, circular imports, async/await mistakes, and encoding issues.
- Fix recommendations & verification: Propose defensive fixes, logging and profiling strategies, and pytest tests to verify the resolution.
- Tools & workflows: Explain using pdb, icecream, rich tracebacks, logging configuration, cProfile, and memory profiler for deeper investigation.
Quick Start
Ask the skill to analyze the provided traceback, produce a minimal reproducible test case, identify the root cause, and propose a code patch plus a pytest to verify the fix.
