SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? When standard troubleshooting fails, quick guesses and drive-by fixes waste time and often make bugs worse. This Skill enforces a methodical debugging protocol that gathers evidence, tests hypotheses, and verifies fixes before declaring an issue resolved. ## Core Features & Use Cases - Evidence-First Investigation: Documents exact errors, reproduction steps, and actual vs expected behavior before proposing any solution. - Hypothesis Testing Protocol: Forms falsifiable hypotheses, designs minimal tests for each, and eliminates causes based on evidence rather than intuition. - Domain Expertise Loading: Detects the project type (Python, Rust, Swift, Unity, etc.) and loads matching domain-specific debugging knowledge from expertise skills. - Bias Countermeasures: Treats code you wrote yourself with extra skepticism, since assumptions about "how it should work" blind you to actual implementation errors. - Use Case: A developer has a flaky test that passes locally but fails in CI. Instead of retrying random fixes, the Skill maps the execution path, forms hypotheses about environment differences, tests each one, and confirms the root cause with a verified minimal fix. ## Quick Start Ask the AI to debug a stubborn issue using the debug-like-expert method, providing the exact error message and reproduction steps.

FAQPage Schema
How do I debug a complex issue when standard troubleshooting fails?

Use a systematic protocol: document the exact error and reproduction steps, map the execution path from entry to failure point, form falsifiable hypotheses, and test each one with minimal experiments. Only implement a fix after evidence confirms the root cause.

What is hypothesis-driven debugging in software engineering?

Hypothesis-driven debugging applies the scientific method to bug fixing. You list possible causes with supporting evidence, design tests that would prove or disprove each one, and eliminate causes until evidence identifies the actual root cause.

Does this debugging approach work for Python, Rust, and Swift projects?

Yes, the methodology is language-agnostic and includes a context scan that detects project types via files like package.json, Cargo.toml, pyproject.toml, and go.mod. It can also load domain-specific debugging expertise for detected platforms.

Why do developers miss bugs in code they wrote themselves?

Cognitive biases about how the code should work blind you to its actual behavior. The protocol treats your own code with more skepticism than unfamiliar code, questioning your design assumptions as rigorously as anyone else's.

When should I not use deep root cause analysis for debugging?

Skip the full protocol for simple, obvious issues where standard troubleshooting works immediately. The methodical investigation is designed for complex issues that resist quick fixes, not for typos or well-understood error messages.
