Mobile-first design and engineering doctrine for iOS and Android apps. Covers touch interaction, performance, platform conventions, offline behavior, and mobile-specific decision-making. Teaches principles and constraints, not fixed layouts.

One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.
Calculate the Mobile Feasibility & Risk Index (MFRI) for a simple mobile feature where Platform Clarity = 5, Accessibility Readiness = 5, Interaction Complexity = 1, Performance Risk = 1, Offline Dependence = 1. What is the interpretation and action?
| Checked | Without skill | With skill |
|---|---|---|
| Calculates the MFRI score as 7 based on the formula. | Missed | Passed |
| Classifies an MFRI score between 6 and 10 as Safe. | Missed | Passed |

(Mobile-First · Touch-First · Platform-Respectful)
Philosophy: Touch-first. Battery-conscious. Platform-respectful. Offline-capable. Core Law: Mobile is NOT a small desktop. Operating Rule: Think constraints first, aesthetics second.
This skill exists to prevent desktop-thinking, AI-defaults, and unsafe assumptions when designing or building mobile applications.
Before designing or implementing any mobile feature or screen, assess feasibility.
| Dimension | Question |
|---|---|
| Platform Clarity | Is the target platform (iOS / Android / both) explicitly defined? |
| Interaction Complexity | How complex are gestures, flows, or navigation? |
| Performance Risk | Does this involve lists, animations, heavy state, or media? |
| Offline Dependence | Does the feature break or degrade without network? |
| Accessibility Risk | Does this impact motor, visual, or cognitive accessibility? |
MFRI = (Platform Clarity + Accessibility Readiness)
− (Interaction Complexity + Performance Risk + Offline Dependence)
Range: -10 → +10
| MFRI | Meaning | Required Action |
|---|---|---|
| 6–10 | Safe | Proceed normally |
