Guide · Install a Claude Code skill

Drop the Design Agent into your Claude Code in five minutes.

A 5-phase pipeline that walks you from inspiration to shipped landing page — the same one we run internally at ColdIQ. Ships as a single Markdown file you drop in ~/.claude/commands/. Free. Hackable. Fork it for your own workflows.

What you will get

One slash command. Five phases. A shippable page.

01 · Trigger

Type /design-agent

Pop it open from any Claude Code session. Pass a one-liner like "B2B SaaS for cold email" and it skips straight to discovery.

02 · Pipeline

Five guided phases

Inspiration → Visual generation → Site build → Polish (micro-interactions) → Ship. The agent picks tools and writes the prompts for you.

03 · Output

A top-1% landing page

Cleaned visuals, hero animation, Lottie micro-interactions, recorded demo, ready-to-post caption. 2-3 hours end-to-end.

DESIGN AGENT online. I'll walk you through 5 phases.
Stop at any time and I resume where we left off.

What are you building? Give me 1–3 sentences:
· product or project name
· what it does, in plain language
· who it's for and the problem it solves

Prerequisites

What you need before you start

01 · Runtime

Claude Code installed

Install via the official one-liner or `npm i -g @anthropic-ai/claude-code`. Works on macOS, Linux, and Windows (WSL).

02 · Plan

Claude Pro / Max

The agent runs on Claude Sonnet 4.6 and Phase 3 hands off to claude.ai/design — both ship with Pro/Max. An Anthropic API key with credits also works for the Sonnet calls.

03 · Optional power-ups

Phase 2 APIs + Phase 4 Lottie

Steps 5–7 wire up Gemini & Kling for direct API gen, ffmpeg for watermark cleanup, and the LottieFiles MCP for micro-interactions. Skip them and the agent falls back to web tools — works, just more clicks.

Step 01

Install Claude Code

If you don't have Claude Code yet, grab it. The slash command we're about to install lives in a folder Claude Code reads at startup, so the order is: Claude Code first, slash command second.

Step 02

Create the commands directory

Claude Code looks for custom slash commands at `~/.claude/commands/`. Each Markdown file in that folder becomes a slash command — `foo.md` becomes `/foo`. The folder may already exist; `mkdir -p` is safe either way.
