What problem does it solve?

This Skill helps you prevent user errors by structurally limiting what actions are possible, so mistakes are blocked before they can happen.

Core Features & Use Cases

  • Input validation constraints: Apply type, format, range, and required-field rules so users cannot submit invalid data.
  • State- and role-based gating: Disable or hide actions until preconditions are met (e.g., edit mode, permissions) to remove wrong-action paths.
  • Forcing-function constraints: Require deliberate multi-step confirmation (e.g., type-to-confirm) so destructive actions cannot be triggered accidentally.

Quick Start

Use the constraint skill when designing a form or destructive flow to identify the best constraint (physical-analog or psychological) that blocks the wrong action and specify what should enable the allowed action.
