negative-contrastive-framing

SKILL.md

Define concepts, quality criteria, and boundaries by showing what they're NOT—using anti-goals, near-miss examples, and failure patterns to create crisp decision criteria where positive definitions alone are ambiguous.

Negative contrastive framing defines something by showing what it's NOT:

Start with initial positive definition, identify why it's ambiguous or fuzzy (multiple interpretations, edge cases unclear), and clarify purpose (teaching, decision-making, quality control). See Common Patterns for typical applications.

Use when clarifying fuzzy boundaries, defining quality criteria, teaching by counterexample, preventing common mistakes, setting design guardrails, disambiguating similar concepts, refining requirements through anti-patterns, creating clear decision criteria, or when user mentions near-miss examples, anti-goals, what not to do, negative examples, counterexamples, or boundary clarification.
