App Behavior

CognitiveFlow v1.0.0 is a mock personalized learning and productivity platform that renders its UI entirely from a JSON data profile. The page is divided into several panels: a top-level app header with a "Load Remote JSON" / "Load Embedded Sample" / "Toggle Theme" control strip, a User Profile column, a Goals & Momentum tracker, an Analytics dashboard, a Projects task list, an Interaction Log, a Data Inspector, and a Study Assistant chat panel.

Load JSON Buttons
Clicking "Load Remote JSON" or "Load Embedded Sample" swaps the app subtitle/description text with a template string populated from the JSON profile.
Toggle Theme
Switches the app between a light and dark color scheme affecting the main content area.
Study Assistant
A textarea accepts user input. "Generate Advice" returns a template plan that echoes the user's typed text alongside JSON-sourced goals and task suggestions. "Celebrate Progress" outputs a fixed motivational task-count summary.
Projects & Tasks
Displays one project ("Wearable Interaction Prototype") with two tasks. Tasks can be checked/unchecked and logged to the Interaction Log in real time.
Mock Goal Progress Slider
A range slider under "Goals & Momentum" lets you manually drag progress from 0–100%, updating the displayed percentage label.
Analytics Panel
Displays three static mock metrics (Active Users: 128, Daily Sessions: 342, Avg Session: 27.5 min) as bar charts. Labeled "Live mock."
Data Inspector
A scrollable panel showing the raw JSON structure driving the UI — useful for verifying data-driven rendering.
Interaction Log
Timestamps and logs all user interactions (task toggles, advice generation) in chronological order during the session.

Things That Didn't Work As Expected

Prompt to Improve the App

You are improving an existing JSON-powered learning productivity app called CognitiveFlow. The app currently loads a user profile from JSON and displays goals, tasks, analytics, and a Study Assistant panel. Several features are cosmetic only. Please make the following improvements: 1. LEARNING STYLE EXPANSION: The app already correctly adapts the "Learning-style strategy" line in Generate Advice and the Data Inspector based on the selected style (Visual / Auditory / Kinesthetic). Extend this further so the selected style also influences the visual presentation of the Projects panel (e.g., Visual → card layout with color-coded priority bars; Auditory → narrative task descriptions; Kinesthetic → step-by-step checklist format), and add a persistent style indicator visible in the User Profile card at all times. 2. REAL AI ADVICE: Replace the hardcoded template in "Generate Advice" with an actual call to the Claude API (claude-sonnet-4-20250514). Pass the user's typed message, their current goals, active project, and selected learning style as context. Stream the response into the output area. 3. NOTIFICATIONS TOGGLE: Make the Notifications button actually toggle between "Enabled" and "Disabled" states, and when enabled, show a subtle toast/banner reminder if a goal deadline is within 7 days. 4. GOAL PROGRESS SYNC: Connect the manual progress slider to the goal's progress value so that dragging it updates the progress bar above it consistently, and also recalculates the "X day(s) remaining" display based on the new value. 5. ANALYTICS SIMULATION: Add a "Simulate Day" button that increments Active Users and Daily Sessions by a small random amount, re-renders the bar chart, and logs the change to the Interaction Log — making the "Live mock" label feel honest. Keep the existing visual design, JSON-driven architecture, and Data Inspector panel. Do not remove any existing features — only extend them.
