One of 14 test cases the skill fixed. Same model, same prompt, with and without the skill.
When a matching template is located in the pattern library, what are the three action steps to complete the task?
| Checked | Without skill | With skill |
|---|---|---|
| States the actions to copy, customize, and validate | Missed | Passed |
The instructions your model reads when the skill loads.
Enforce pattern-first development by checking the pattern library before implementing new functionality.
ALWAYS check patterns before writing new code:
ls patterns_library/api/ # API route patterns
ls patterns_library/ui/ # UI component patterns
ls patterns_library/database/ # Database patterns
ls patterns_library/testing/ # Testing patterns
See patterns_library/README.md for the complete index.
If pattern exists: Copy, customize, validate.
If missing: Search codebase, implement following conventions, report gap.
