Hypothesis-Based Debugger FAQs

Question 1

What is hypothesis-based debugging?

Accepted Answer

It is a scientific approach to software troubleshooting where you form specific, testable theories about a bug and collect runtime evidence to prove or disprove them before making code changes.

Question 2

How does the debug server operate?

Accepted Answer

The skill automatically launches a lightweight Node.js server on port 3947 that captures structured JSON logs from your application, allowing Claude to analyze program flow in real-time.

Question 3

Does this skill leave debug code in my repository?

Accepted Answer

No. The skill follows a strict cleanup protocol that removes all instrumentation blocks, stops the background server, and deletes temporary log files once the fix is verified.

Question 4

Can I use this for non-JavaScript projects?

Accepted Answer

While the primary instrumentation templates are optimized for JS/TS, the core methodology and logging schema can be adapted for any language capable of making HTTP requests.

Question 5

Why is runtime evidence required before fixing?

Accepted Answer

Runtime evidence ensures that the actual root cause is identified, preventing 'band-aid' fixes that might temporarily hide symptoms while leaving the underlying logic error intact.
