Create Rule

This is meta-tooling for when you catch yourself or an implementation agent making the same mistake twice. The idea is simple: if you're saying "you're absolutely right, I should have done it differently," that's your signal to codify the fix as a rule. The skill guides you through creating contrastive examples (incorrect vs correct patterns) that load into every session as behavioral guardrails. It emphasizes token efficiency and path scoping so you're not loading frontend rules when editing backend code. The approach is grounded in research showing that showing both the wrong and right pattern eliminates ambiguity better than positive examples alone. Useful when you notice patterns in agent mistakes rather than one-off issues.
