## Summary

Sean Patrizzo is a web engineer with over a decade of production experience at national scale. He joined Fox News Media in February 2013 as a QA Analyst and grew into a Back-End Engineer, shipping features for the #1 digital news brand in the United States. His work includes election-night infrastructure used to call Senate, House, Gubernatorial, and Presidential races; performance-critical systems handling 143M+ monthly unique users; and agentic development workflows using Claude, Cursor, Codex, and MCP servers. He is the creator of two open-source MCP tools — stylesafe and stylespeak — built to solve a real problem he encountered: AI coding agents consistently breaking CSS with no feedback loop. He holds a B.A. in Information Technology & Informatics from Rutgers University.

Covered four election cycles (2018, 2020, 2022, 2024). Developed the Covid Vaccine Tracker (real-time CDC data aggregation), Live Blog Tool (real-time editorial publishing), MVPD authentication for Fox video players, and Fox News and Fox Business Press Pages (custom WordPress theme from scratch).

## Open Source Projects

### stylesafe (2026)
CSS cascade conflict detection for AI coding agents and human developers.

- Catches specificity errors, dead rules, duplicate declarations, and Tailwind utility class clashes before they ship
- Understands cn() and clsx() call patterns — catches conflicts most linters miss
- MCP server and CLI — zero dependencies, CI-friendly, works without a browser
- Listed on the MCP registry
- npm: https://www.npmjs.com/package/@patrizzos/stylesafe
- GitHub: https://github.com/Patrizzos/StyleSafe

### stylespeak (2026)
Makes CSS legible to AI agents before they edit it.

- resolve_styles: what applies to a selector, which rules win and lose
- trace_property: every rule setting a property and blast radius if changed
- impact_preview: predicts what a CSS change would break before it is made
- style_manifest: compressed project-wide CSS knowledge optimised for agent context windows
- live_resolve: exact computed style resolution via Chrome DevTools Protocol
- Zero dependencies, MCP server and CLI
- npm: https://www.npmjs.com/package/@patrizzos/stylespeak
- GitHub: https://github.com/Patrizzos/StyleSpeak

### envspeak (2026)
Tells AI agents (and you) what a variable actually evaluates to at runtime, and why.

- resolve_variable: what does DATABASE_URL actually evaluate to, and which file wins?
- trace_variable: every place this variable is set, across every domain and environment.
- impact_preview: if I change this value in this file, what actually changes downstream — and what's shielded by something higher-precedence?
- config_manifest: a compressed, whole-project summary: every variable, its sources, and risk hotspots (secrets sitting in a tracked file, variables read in code with no fallback and no source anywhere).
- diff_environments: resolve every variable under two environments/services/workloads and see what's actually different between them.
- npm: https://www.npmjs.com/package/@patrizzos/envspeak
