One of 9 test cases the skill fixed. Same model, same prompt, with and without the skill.
Our repository quality configuration file at `.moai/config/sections/quality.yaml` needs to be set up to enable characterization-first refactoring over standard TDD. Which key path and value sets this mode?
| Checked | Without skill | With skill |
|---|---|---|
| Sets development_mode to ddd under the constitution block | Missed | Passed |
The instructions your model reads when the skill loads.
[NOTE] This workflow is selected based on .moai/config/sections/quality.yaml:
constitution:
development_mode: ddd # or tdd
When to use this workflow:
development_mode: ddd → Use DDD (this workflow)development_mode: tdd → Use TDD instead (moai-workflow-tdd)Key distinction:
Domain-Driven Development provides a systematic approach for refactoring existing codebases where behavior preservation is paramount. Unlike TDD which creates new functionality, DDD improves structure without changing behavior.
