njs14 Apply engineering principles
Treat the request text that activated this skill as the decision or work item to assess.
Read the principle catalog. Select only the principles whose trigger matches the concrete decision. State each selected principle in plain language, apply its test to the actual artifact, and resolve conflicts by preserving safety, user intent, and executable evidence. Principles guide judgment; they do not authorize destructive, public, paid, privileged, or out-of-scope action.
Prefer one strong principle over a pile of labels. Finish by naming the changed decision and the evidence that shows the principle improved the result.
