Proto Cog - Build Prototypes You Can Click

Build prototypes you can click. UI/UX wireframes, app mockups, and fully interactive HTML prototypes — from napkin sketch to clickable experience in one prompt.

Every other AI design tool gives you static images. CellCog builds working prototypes — real HTML, real interactions, real user flows you can click through and share with stakeholders. Landing pages, mobile app screens, SaaS dashboards, design systems — prototyped and playable, not just pretty.

Prerequisites

This skill requires the cellcog skill for SDK setup and API calls.

clawhub install cellcog

Read the cellcog skill first for SDK setup. This skill shows you what's possible.

Quick pattern (v1.0+):

# Fire-and-forget - returns immediately
result = client.create_chat(
    prompt="[your prototype request]",
    notify_session_key="agent:main:main",
    task_label="prototype-task",
    chat_mode="agent"  # Agent mode for most prototypes
)
# Daemon notifies you when complete - do NOT poll

Why Interactive Prototypes Matter

Static mockups create a fundamental gap: stakeholders see pictures, not experiences. The difference matters:

CellCog generates real HTML/CSS/JS prototypes hosted on live URLs. Share a link, get feedback on the actual experience — not on someone's imagination of the experience.

What You Can Prototype

Landing Pages

Validate your messaging and design:

• SaaS Landing Pages: "Create a landing page for an AI writing assistant — hero, features, pricing, testimonials, CTA"
• Product Launch Pages: "Build a launch page for a new fitness app with countdown and email signup"
• Event Pages: "Create a conference landing page with schedule, speakers, and registration"
• Portfolio Sites: "Build a personal portfolio landing page for a UX designer"

Example prompt:

"Create an interactive landing page prototype for 'FlowState' — a productivity app for developers:

Sections:

• Hero: 'Code in the zone. Stay in the zone.' with app screenshot and CTA
• Problem: Distractions kill developer flow (statistics)
• Solution: How FlowState blocks distractions intelligently
• Features: 3-4 key features with icons
• Pricing: Free, Pro ($12/mo), Team ($8/user/mo)
• Testimonials: 3 developer quotes
• Final CTA

Style: Dark theme, developer-friendly, monospace accents Make all buttons and navigation interactive."

Mobile App Screens

Design full app experiences:

• Onboarding Flows: "Create a 5-screen onboarding flow for a meditation app"
• Core Features: "Prototype the main dashboard and navigation for a fitness tracking app"
• E-commerce: "Build a product browse → detail → cart → checkout flow for a fashion app"
• Social Features: "Prototype a profile page, feed, and messaging interface"

Example prompt:

"Prototype a mobile food delivery app (phone-sized viewport):

Screens:

1. Home — restaurant grid with search and category filters
2. Restaurant — menu with items, ratings, delivery time
3. Item detail — customization options, add to cart
4. Cart — order summary, delivery address, payment
5. Order tracking — live status with map placeholder

Make navigation between screens work with smooth transitions. Style: Clean, modern, Uber Eats / DoorDash inspired."

SaaS Dashboards

Prototype complex business tools:

• Analytics Dashboards: "Create a marketing analytics dashboard with real chart interactions"
• Admin Panels: "Build a user management panel with tables, filters, and modals"
• CRM Interfaces: "Prototype a sales pipeline view with drag-and-drop kanban board"
• Settings Pages: "Create a comprehensive settings page with tabs, forms, and toggles"

Example prompt:

"Prototype a SaaS project management dashboard:

Left sidebar: Navigation (Projects, Tasks, Team, Reports, Settings) Main area:

• Overview: KPI cards (tasks completed, overdue, in progress)
• Kanban board: Columns for To Do, In Progress, Review, Done
• Task cards with assignee avatars, priority tags, due dates

Interactions:

• Sidebar navigation switches views
• Clicking a task card opens a detail modal
• Filter dropdown for project/team member

Style: Clean, professional, Notion/Linear inspired."

Design Systems & Components

Build reusable design foundations:

• Component Libraries: "Create a UI component library: buttons, inputs, cards, modals, navigation"
• Style Guides: "Build an interactive style guide showing typography, colors, spacing, and components"
• Form Patterns: "Prototype common form patterns: login, signup, multi-step wizard, settings"
• Navigation Patterns: "Create examples of sidebar nav, top nav, bottom tab bar, and hamburger menu"

Wireframes

Quick structural explorations:

• Low-Fidelity Wireframes: "Create grayscale wireframes for a blog platform — home, article, author pages"
• User Flows: "Wireframe the complete signup → onboarding → first action flow for a project management tool"
• Layout Explorations: "Show 3 different layout approaches for a real estate listing page"
• Information Architecture: "Wireframe the navigation structure for an e-learning platform with courses, lessons, and progress tracking"

Prototype Features

CellCog prototypes can include:

Output Formats

Interactive HTML is the default. That's the whole point — prototypes you can click.

Chat Mode for Prototyping

Use "agent" for most prototypes. Landing pages, individual app screens, and component designs execute well in agent mode.

Use "agent team" for full application prototypes — multi-screen apps where navigation, state, and user flows need to work together cohesively.

Example Prompts

SaaS landing page:

"Create a landing page for 'CodeReview.ai' — an AI code review tool:

Hero: 'Ship better code. Ship it faster.' with demo video placeholder Social proof: 'Trusted by 500+ engineering teams' Features: AI-powered reviews, integration with GitHub/GitLab, security scanning Pricing: Starter (free), Pro ($29/mo), Enterprise (custom)

Dark theme, developer-focused, green accent color. All navigation and CTAs should be interactive."

Mobile app prototype:

"Prototype a habit tracking app (mobile viewport):

Tab bar: Today, Habits, Stats, Profile

Today screen: List of today's habits with checkboxes, streak counts, and progress ring Habits screen: All habits with edit/delete, add new habit button Stats screen: Charts showing completion rates, longest streaks, weekly/monthly view Profile screen: Settings, notification preferences, export data

Tab navigation should work. Checking habits should animate. Style: Minimal, calming, inspired by Streaks app."

Design system:

"Build an interactive design system for a fintech startup:

Colors: Primary (deep blue), secondary (teal), accent (amber), semantic (success/warning/error) Typography: Scale from h1 to body to caption with clear hierarchy Components:

• Buttons (primary, secondary, ghost, destructive — each with hover/active/disabled states)
• Input fields (default, focused, error, disabled)
• Cards (simple, interactive, stat card)
• Table with sortable headers
• Modal dialog
• Toast notifications

Show each component with interactive states. Professional, banking-grade aesthetic."

Wireframe exploration:

"Create 3 different layout approaches for an AI chatbot interface:

Option A: Full-page chat (like ChatGPT) Option B: Side panel chat with main content area Option C: Floating chat widget

Each should include: message input, conversation history, suggested prompts, and settings access. Grayscale wireframes, focused on layout and information hierarchy."

Tips for Better Prototypes

1. Describe the interactions: "Button opens a modal" or "Tabs switch content" — tell CellCog what should happen, not just what should appear.

2. Reference existing products: "Like Notion's sidebar" or "Stripe's pricing page" communicates more than paragraphs of description.

3. Specify viewport: "Mobile phone viewport" vs "Full desktop" changes the entire design approach.

4. Include realistic content: Real text, real numbers, real labels — not "Lorem ipsum". Prototypes with real content get better feedback.

5. State the purpose: "For user testing", "For investor demo", "For developer handoff" — context shapes fidelity level.

6. Think in flows, not pages: "Signup → Onboarding → Dashboard" is more useful than 3 disconnected page requests.
