Systematic Debugging FAQs

Question 1

What happens if three or more fix attempts fail?

Accepted Answer

The process mandates that you stop and question the architecture. If three fixes fail, it usually indicates a fundamental design flaw or an 'inertia' problem rather than a simple bug, requiring a discussion with a human partner.

Question 2

How does this skill handle bugs in multi-component systems?

Accepted Answer

It implements diagnostic instrumentation at every boundary (e.g., Workflow → Build → API). By logging data entry and exit at each layer, it isolates exactly where the system breaks before attempting a fix.

Question 3

What is the 'Iron Law' of this debugging skill?

Accepted Answer

The Iron Law states that no fixes can be proposed or implemented until Phase 1 (Root Cause Investigation) is complete. Proposing solutions before understanding the cause is considered a violation of the process.

Question 4

When should I use the Systematic Debugging skill?

Accepted Answer

Use it for any technical issue including test failures, production bugs, or performance problems. It is especially critical when you are under time pressure or when previous fix attempts have failed.

Question 5

Does this skill require writing tests?

Accepted Answer

Yes. Phase 4 requires creating a failing test case that reproduces the issue before any implementation begins, ensuring the fix is verified and permanent.
