A new platform-agnostic website specification offers developers a comprehensive checklist of technical features every decent site should implement. The spec covers ten areas including HTML basics, search visibility, accessibility through WCAG standards, security headers, and AI legibility. Each requirement maps to established standards from WHATWG, W3C, and IETF RFCs rather than opinion-based guidance.

The specification works across WordPress, Drupal, Next.js, Astro, Hugo, Django, and static HTML sites. Implementation hints follow the standards, not the other way around. The project emphasizes practical application over theoretical discussion, with each topic explaining what it is, why it matters, and how to implement it.

Developers can audit sites against the checklist, learn implementation details, and contribute improvements via GitHub pull requests. Every page includes an 'Edit on GitHub' link with sources credited. The spec exposes an open MCP server for agent integration and supports text/markdown delivery through /llms.txt endpoints.

This fills a real gap in web development documentation by providing a single reference for essential technical requirements. The focus on standards compliance and platform agnosticism makes it immediately useful for teams building modern, accessible, and AI-friendly websites.
