Design Patterns for AI

Build agentic systems that verify their work with evidence, not opinion.

Added July 5, 2026 · Last analysed July 5, 2026 · via Hacker News · 50% unique tagline

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 5 July 2026; the live site may have changed since.

Design Patterns for AI looks production-ready overall, with a thorough launch checklist and clean crawl signals. Worth fixing first: no Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Hacker News on July 5, 2026. The site is served through Cloudflare, with a domain registered 4 weeks before launch. We've detected 7 technologies on this site, covering DNS providers, CDN, email forwarding, and meta-frameworks. The stack includes Astro, Cloudflare, and Cloudflare DNS.

It's running the same core stack as 207 other launches and tighter on security headers than most Hacker News launches.
