Detect when code changes reopen closed domains or widen boundary conditions — expanding d(S) where it was resolved. Uses Hamming distance to measure change locality and delta-epsilon to characterize the exact boundary where a change crosses into another semantic domain. Respects the domain partial order: drift in a prerequisite domain invalidates dependent domains. Use when reviewing diffs, auditing generated code, or verifying refactors.
Create a new health domain. Triggers on "add domain", "new domain", "create domain for", "I want to track", or any request to add a new health tracking area.
Detect and analyze homograph/homoglyph attacks in phishing emails, URLs, and domains. Use this skill whenever the user mentions phishing analysis, email security, domain impersonation, Unicode attacks, homoglyph detection, or needs to inspect suspicious sender names, subjects, or URLs for character substitution attacks. Trigger even if the user just says "check this email" or "analyze this URL" if there's any suspicion of spoofing or impersonation.
How to pentest Docker registries (port 5000). Use this skill whenever you need to enumerate, exploit, or backdoor a Docker registry service. Trigger this when you discover port 5000 open, see Docker registry fingerprints, need to pull/push images from a registry, want to extract secrets from container images, or are working on container security assessments. Don't forget to use this for any Docker registry enumeration or exploitation tasks.

Send emails, buy forwarding inboxes, manage custom subdomains, and read messages programmatically via x402. USE FOR: - Sending emails (one-off or from custom addresses) - Buying a forwarding inbox (username@stableemail.dev) - Purchasing custom email subdomains (you@yourname.stableemail.dev) - Reading and managing inbox messages programmatically - Setting up catch-all forwarding for subdomains - Managing authorized signers for shared subdomains TRIGGERS: - "send email", "email this to", "notify by email" - "buy inbox", "forwarding address", "email inbox" - "custom domain", "subdomain", "email subdomain" - "read emails", "check inbox", "list messages" - "email address", "disposable email", "temporary email" ALWAYS use agentcash.fetch for stableemail.dev endpoints. IMPORTANT: Use exact endpoint paths from the Quick Reference table below.
Domain detection — classifies projects by signals (directories, manifests, dependencies, keywords) into domains for review and research targeting
Apply universal naming principles: avoid Manager/Helper/Util, use intention-revealing names, domain language, verb+noun functions.
Use when configuring Docker networks, debugging container connectivity, or setting up service discovery between containers. Prevents using the default bridge network in production, which lacks DNS resolution and automatic service discovery. Covers bridge, host, overlay, macvlan, ipvlan, and none drivers, DNS resolution, port mapping, network isolation, and user-defined networks. Keywords: docker network create, --network, -p, --publish, bridge, overlay, macvlan, docker-compose networks, DNS, service discovery, containers can't talk to each other, network not working, connect containers.
Use when containers cannot reach each other, DNS resolution fails between services, or published ports are not accessible from the host. Prevents connectivity failures from using the default bridge network, which lacks automatic DNS resolution and proper isolation. Covers DNS failures, connection refused, port mapping issues, iptables conflicts, overlay network problems, subnet collisions. Keywords: docker network, DNS resolution, connection refused, bridge, overlay, iptables, port mapping, docker network inspect, subnet, can't reach container, port not accessible, network error, DNS not resolving.
Optimize websites for Hebrew SEO and GEO (Generative Engine Optimization) on Google.co.il and AI search engines (ChatGPT, Perplexity, Gemini, Copilot, Claude). Use when user asks about Hebrew keyword research, Israeli SEO, .co.il domain optimization, Hebrew schema.org markup, AI search visibility, GEO optimization, EEAT, or asks about "kidum atarim", "milot mafteach", "SEO", "GEO", or Israeli search ranking. Includes Hebrew morphological analysis, Princeton GEO methods, platform-specific AI optimization, EEAT principles, JSON-LD structured data, and Israeli business schema (Shabbat hours, kosher certification). Do NOT use for paid advertising campaigns or social media marketing.
Implements the Syncfusion WPF DomainUpDown (SfDomainUpDown) control for cycling through predefined item lists using spin buttons. Use this when adding domain selectors, item selectors with up/down buttons, or controls that navigate through collections using increment/decrement buttons in WPF applications. Covers item population, spin button alignment, styling, auto-reverse, and data binding with custom templates.
NextDNS integration guides for third-party platforms and services. This skill should be used when integrating NextDNS with routers, home automation systems, network management platforms, or other third-party services. Triggers on tasks involving Tailscale, Home Assistant, Ubiquiti, pfSense, OpenWrt, or other platform-specific NextDNS configurations.
Configure DNS records for domains and subdomains. TRIGGERS - Use when user needs help with dns-configuration related tasks.
Analyze a domain's backlink profile using Ahrefs: see who links to the domain, source Domain Rating, anchor text, link type, and when each link was first seen. Use when user says "Ahrefs backlinks", "backlink profile", "who links to", "link analysis", or "referring pages".
