One of 3 test cases the skill fixed. Same model, same prompt, with and without the skill.

1 of 3

Prompt

Our team is reviewing a monolithic service file that has grown hard to maintain, full of custom helper functions and nested logic. Please analyze this setup and provide a comprehensive architectural review. Include a clear text diagram showing how to isolate the business domain, detail the key trade-offs involved in restructuring, and give us a step-by-step recommendation list for the refactor.

What was checked, without and with the skill
Checked	Without skill	With skill
Recommends organizing code into domain-bounded modules instead of generic utility modules	Missed	Passed
