Domain Analyzer: One-Stop Domain Intelligence for Your AI Agents

Where this fits

You're evaluating a potential acquisition target, and your agent needs to verify the domain's ownership history, SSL health, and SEO footprint—all in one pass. Instead of wiring up five separate APIs and stitching together inconsistent outputs, you can drop in the domain-analyzer skill. It gives your agent a single orchestrated workflow for domain intelligence, so you move from "I wonder" to "here's the full picture" without manual digging.

Why agents benefit

• Multi-source synthesis: Fuses WHOIS, DNS, SSL, tech stack, and backlink data into one coherent report, so your agent doesn't have to reconcile data from disparate vendors.
• Context-aware tool selection: The skill's workflow first calls sandbase_describe_tool to inspect each capability's schema, ensuring the agent only uses arguments that actually exist—reducing API errors.
• Security-first checks: Includes domain reputation and SSL validation, which is critical for pre-acquisition due diligence or phishing-scope analysis.
• SEO and competitive signals: Pulls live Google SERP data via DataForSEO, letting your agent benchmark a domain's visibility against competitors without extra tooling.
• Structured exploration: The skill nudges the agent to understand the research question before firing off calls, leading to more relevant results and fewer wasted queries.

Practical scenarios

Acquisition due diligence

Your agent evaluates a startup's domain before a purchase. It runs WHOIS to check ownership history and expiration risk, SSL to confirm valid certificates, and tech stack detection to see if the site runs on maintainable frameworks. The agent then cross-references backlink data to flag any spammy link profiles.

Security assessment

You're investigating a suspicious domain. The agent performs DNS lookups to map infrastructure, checks SSL configuration for weak ciphers, and pulls reputation scores to see if the domain is blacklisted. This helps you decide whether to block traffic or escalate to incident response.

Competitive analysis

You want to know how a rival's site is built and ranking. The agent maps the site structure with Firecrawl, detects the tech stack, and pulls organic SERP data to see which keywords they dominate. You get a clear picture of their strengths and gaps to exploit.

Add it to your agent workflow

Install the skill with a single command:

npx skills add sandbaseai/sandbase-skills --skill domain-analyzer

Then in your agent's prompt, reference the skill and let it orchestrate. For example:

Use the domain-analyzer skill to analyze example.com. Focus on WHOIS ownership and SSL health, and provide a summary of any red flags.

The agent will call sandbase_describe_tool first, then execute the relevant tools and return a structured report.

Compare before adopting

Before committing, compare this skill against alternatives like standalone WHOIS or SSL checkers. Look for: quality signals—does it return accurate, up-to-date data? Maintenance freshness—check the GitHub repo's last commit and issue response time. Alternatives—are there other multi-tool skills that fit your stack better? Workflow fit—does the skill's tool schema match your existing agent's calling conventions? The README's API map is a good starting point for that evaluation.

Why it is worth tracking

With 60 stars and active development from sandbaseai, this skill shows real community traction. It consolidates a broad set of domain intelligence tools into one agent-friendly package, which is rare—most similar efforts only cover one or two data sources. Track it now because it's likely to evolve with new tools and better error handling. When your next domain research task arrives, you'll want this skill ready.
