What problem does it solve?
Interfaces that respond too slowly break user flow and make products feel sluggish, but teams often lack a concrete latency target or a plan for what to show when fast responses are impossible. This Skill applies the Doherty Threshold to pinpoint where response times degrade the user experience and prescribes the right feedback pattern for each latency band.
Core Features & Use Cases
- Latency Diagnosis: Maps response times to user perception bands (instant, fast, slow, broken) to identify which interactions violate the sub-400ms target.
- Feedback Pattern Selection: Prescribes immediate visual acknowledgment, loading indicators, progress bars, optimistic UI, or skeleton screens based on how long an operation actually takes.
- Performance Budgeting: Helps set latency budgets for high-frequency interactions like transitions, autocomplete, search, and button feedback.
- Use Case: When reviewing a search feature that takes 800ms to return results, use this Skill to determine that a skeleton screen should appear immediately while results load, rather than leaving the interface unresponsive.
Quick Start
Ask the AI to audit your interface's key interactions against the Doherty Threshold and recommend feedback patterns for any response that exceeds 400ms.
