How To Use Claude Code To Build Insanely Beautiful Sites With Opus 5.5

Highlights

• Opus 5.5 is the preferred model for web design output inside Claude Code.

• Adding business context directly to a CLAUDE.md file prevents loss of conversion intent during repeated site redos.

• AI models default to specific visual habits, such as Opus defaulting to off-white or cream colors.

• The Hallmark skill refines agent layouts and spacing to eliminate default AI-generated visual aesthetics.

• A design.md file downloaded from sites like aura.build locks in visual branding rules like color schemes and fonts across site rebuilds.

• The Scroll World skill integrates generative AI video platforms via MCPs to turn static pages into 3D scrollable camera journeys.

• Automated code review platforms like Code Rabbit identify bugs, generate fix prompts for Claude Code, and secure repositories via deep scans.

   Environment Setup for Claude Code

   Getting started with Claude Code requires installing Warp for terminal management and VS Code for inspecting code changes made by the AI. Claude Code executes within specific local project directories opened via terminal commands like cd and mkdir. Sessions run directly in the terminal, giving the AI model direct agency to create, edit, and modify project files locally.

   • Claude Code requires a terminal application such as Warp to execute commands on a local machine.
   • VS Code serves as the visual file editor alongside terminal interactions.
   • Basic terminal commands manage directory navigation and local session initialization.

   Core CLI Commands and Navigation

   Claude Code provides built-in forward-slash commands to manage operations, model selection, and memory. Opus 5.5 handles front-end design creation, while Sonnet and Fable serve simpler or specialized tasks. Command options like context and compact monitor and compress memory space, whereas rename and resume prevent lost sessions across terminal restarts.

   • The model command switches between Opus 5.5, Sonnet, and Fable based on task complexity.
   • Context management commands optimize or clear token limits during active sessions.
   • Session persistence relies on explicit rename and resume commands rather than automatic web saves.

   Stage 1: Interactive Project Planning

   Activating plan mode forces Claude Code into a conversational discovery state before generating project files. The model asks targeted questions about tech stack choices, layout sections, design targets, and site objectives. Upon plan finalization, switching to auto mode lets Claude Code autonomously write code and launch a temporary local test server.

   • Plan mode restricts file modifications to force explicit requirements gathering.
   • Next.js provides the foundation for building project structures rapidly.
   • Auto mode executes approved architectural plans into functional local web pages.
4. 08:02 - 10:08

   Stage 2: Persistent Business Context via CLAUDE.md

   Because new Claude Code sessions lack history, CLAUDE.md acts as persistent project memory injected at session startup. Running the init command outlines basic setup rules and project structure. Manually supplementing the file with specific business objectives ensures that future AI refactors keep focus on primary conversion metrics.

   • CLAUDE.md automatically injects project memory into every new chat context window.
   • The init command creates an initial documentation structure based on codebase inspection.
   • Adding explicit business conversion goals preserves strategic intent across future site revisions.
5. 10:08 - 11:41

   Stage 3: Escaping AI Aesthetics with Hallmark

   To fix generic AI layout patterns, custom skills provide specialized instruction rules. Installing and running the Hallmark skill forces the model to re-evaluate and overhaul page structure, typography hierarchy, and spacing. Using terminal mode allows quick installation of system dependencies directly inside the active prompt window without breaking session workflow.

   • Skills contain tailored instruction sets executed via forward-slash commands.
   • The Hallmark skill overrides standard AI design templates with sophisticated spacing and layouts.
   • Terminal mode enables executing shell commands directly inside Claude Code using an exclamation mark.
6. 11:41 - 14:05

   Stage 4: Visual Rule Enforcement with design.md

   AI models tend to rely on built-in visual defaults, such as Opus defaulting to off-white palettes regardless of layout changes. Creating or downloading a design.md file defines explicit rules for color tokens, typography, and spacing variables. Referencing design.md in prompts forces Claude Code to adhere to fixed branding guidelines during full site redesigns.

   • Opus 5.5 defaults to off-white and warm cream palettes unless strictly constrained.
   • A design.md file locks in explicit color schemes, typography, and spacing systems.
   • Pre-built design files can be downloaded from repositories like aura.build.
7. 14:05 - 18:13

   Stage 5: Continuous Deployment via GitHub and Vercel

   Production sites require remote hosting and version control rather than temporary localhost links. Initializing Git commits enables project state reversion if new features break functionality. Linking GitHub repositories to Vercel triggers automated builds on every push, while installing CLI tools lets Claude Code inspect remote build logs and patch errors directly.

   • Git commits save code state checkpoints to allow instant reverts when errors occur.
   • Connecting GitHub repositories to Vercel automates web deployments upon remote updates.
   • CLI tools for GitHub and Vercel give Claude Code direct ability to resolve deployment issues.
8. 18:13 - 21:42

   Stage 6: 3D Cinematic Storytelling with Scroll World

   Transforming static landing pages into immersive experiences uses the Scroll World skill

   • The Scroll World skill generates continuous 3D camera transitions tied to scroll positioning.
   • Git branches isolate experimental feature development from the live production codebase.
   • Model Context Protocols (MCP) connect Claude Code directly to AI video generators like Runway or Higgsfield.
