Day 5 Data Structure Codex AI Architect

Codex Client Workspace-based service design (UI/UX) Tasks

Limitations in user convenience, disruption of consistency between screens, and unnecessary movement paths that startups face during the service planning stage.
This is a user-centered review task board that automatically analyzes and improves using Codex.

Day 5 Startup MVP Tasks

From reviewing screens to establishing consistency and optimizing journeys — experience the core workflow of using Codex as a UI/UX reviewer and first user.

TASK 1
Task 1

Task 1. Review the screen from the user’s perspective

Task 01: Review of screen structure and layout from the perspective of a novice user (User Experience Review)

By deriving key entities and relationships (Mermaid ERD) from planning meeting minutes written in natural language, the gap in data model understanding between planners and developers is resolved with AI.

Task 2. Review screen consistency

Task 02: Sorting terminology, buttons, and feedback consistency between screens (Screen Consistency Review)

By mapping button location rules, common names, and status message specifications scattered across multiple screens, we derive consistency violation points and create a common guide.

Mission 1. Become a first-time user

Mission 01: Real-time predicament review based on older/novice persona

By injecting the persona of an older self-employed person who is somewhat awkward at using a smartphone into AI, we track the psychological inconveniences they may experience during actual planning and error loops.
