How We Built a Client Site in a Single Afternoon Using AI and @sleekcms/sync

The brief Small professional services firm. Needed a clean marketing site: homepage, services section with individual service pages, about page, a blog, and a contact form. Timeline: tight. Budget: fixed. The kind of project where the question isn't whether you can build it — it's whether you can build it without spending three days on project scaffolding before writing a single line of content-specific code. This is what that afternoon looked like. One command to start The cms-sync is the entry point. One command creates the local workspace and starts the file watcher: npx @sleekcms/sync --token YOUR_AUTH_TOKEN On first run, the workspace appears with three files before you've written anything: my-site/ ├── CLAUDE.md ├── AGENT.md └── .vscode/ └── copilot-instructions.md These context files are the key. CLAUDE.md for Claude and Claude Code. AGENT.md for GitHub Copilot in agent mode. .vscode/copilot-instructions.md for GitHub Copilot in VS Code. Each contains the complete SleekCMS site-building reference — file naming conventions, model syntax, template helpers, field types, content format. Open the workspace in Cursor (or VS Code with Copilot, or Claude Code). The AI already knows how to build a SleekCMS site. No setup prompt, no pasting documentation. The prompt We kept it realistic — not a paragraph of precise technical specification, but the kind of description you'd give a developer on a call: Build a professional services marketing site with: - A homepage with a hero section, services overview, client logos, and a contact CTA - A services page listing all services, and individual service detail pages - An about page - A blog with individual post pages - A shared header and footer - A contact form - Tailwind CSS styling - SEO meta tags on every page What the AI generated The output was a complete set of working files: models/pages/_index.model models/pages/services.model models/pages/services[].model models/pages/about.model models/pages/blog[].model models/page
