Child Nested Instructions

Child instruction files must extend their parent's scope without contradicting it. Contradictions between levels create confusion.

Antipatterns

Writing "ignore parent instructions" in a child file to start fresh. The check detects "ignore parent" and "ignore all" as override language. Child files should extend, not replace.
Using "override everything above" to reset inherited directives. The check flags "override everything" and "override all" as blanket overrides.
Phrasing a narrow exception as a broad override ("ignore all previous rules, then re-add the ones we want"). Even if the intent is selective, the language triggers the blanket-override pattern.

# Frontend Rules

Use React 18 for components.
Prefer CSS modules over inline styles.

# Frontend Rules

Ignore parent instructions.
Override everything from the root file.

Detects parent-override language (ignore parent, override everything). Does not evaluate whether the override scope is appropriate.
