Signal & Noise Tools

Signal & Noise Tools Companion plugin to the Signal & Noise theme for juanlentino.com. It holds the operational tooling that doesn't belong in a presentation theme — SEO, security, analytics, admin surfaces, and AI-assisted editorial helpers — so the theme stays focused on design and the plugin owns behaviour. Built on WordPress 7.0's Abilities API and AI Client: it both registers the site's capabilities for AI agents and ships in-editor AI helpers (alt text, meta descriptions, excerpts, brand-voice checks) that call the site owner's configured model provider. What it does - SEO — meta descriptions, canonical handling, Open Graph cards, sitemaps + IndexNow, a redirect manager with a 404 capture log, and cache excludes (replaces a third-party SEO plugin) - Security — WordPress hardening (Permissions-Policy, REST user-enumeration lock, XML-RPC off), a custom login slug, and a read-only login-defense panel over the edge login-guard Worker's decisions; the five headers Cloudflare emits at the edge (CSP, HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) are drift-probed by a health check rather than duplicated in PHP - Analytics — first-party, cookieless edge analytics
