Domain Intelligence: Give Your Agent OSINT Superpowers

Where this fits

You're building a security agent that triages suspicious links for a SOC. Or a competitive research bot that profiles a startup's infrastructure before a sales call. Either way, you need structured domain data — ownership, DNS records, SSL validity, reputation — without writing a dozen API integrations yourself. The domain-intelligence skill bundles these lookups into a repeatable agent workflow, so your agent can answer "who runs this domain and how secure is it?" in one pass.

Why agents benefit

• Zero integration work: The skill wraps six SandBase tools (WHOIS, DNS, SSL, age, reputation, security headers) behind a unified interface. Your agent calls sandbase_describe_tool to learn the schema, then sandbase_call_tool — no hardcoded API keys or parsing logic needed.
• Context-aware tool selection: The skill's workflow instructs the agent to first understand the research question, then pick only the relevant tools. That means your agent won't waste calls on SSL checks when the user only needs ownership data.
• Standardized output: Every tool returns structured data, so your agent can reason over results (e.g., "domain age > 5 years + low reputation score = likely parked domain") without wrestling with inconsistent formats.
• Reproducible research: The skill enforces a consistent sequence — describe, call, synthesize — making your agent's domain investigations auditable and easier to debug.
• Covers the full surface: From infrastructure mapping (DNS, SSL) to risk scoring (reputation, security headers), the skill gives your agent a complete domain profile in one workflow.

Practical scenarios

Phishing triage for a security operations agent

A user pastes a suspicious URL. The agent runs strale_whois_lookup to check registration recency, strale_domain_reputation for blacklist hits, and strale_header_security_check to see if the site lacks common protections. It returns a risk score with evidence — no human needed.

Competitive infrastructure mapping for market research

Your agent needs to profile a competitor's tech stack. It uses strale_dns_lookup to enumerate subdomains and mail servers, strale_ssl_check to see certificate issuer and expiry, and strale_domain_age_check to estimate how long they've been live. The output feeds a comparison report.

Vendor due diligence for procurement

Before signing a contract, your agent checks the vendor's domain history with WHOIS, verifies SSL validity, and scans security headers. It flags anomalies like recently changed registrant info or missing HSTS, giving your team a quick trust signal.

Add it to your agent workflow

Install the skill with:

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

Then in your agent's system prompt, point it to the skill's README and API map. A minimal usage example for a lookup:

User: Check the domain example.com
Agent: I'll start by understanding the request. I need WHOIS, DNS, and SSL data. Calling sandbase_describe_tool for strale_whois_lookup...

The skill handles the rest — your agent just follows the workflow steps.

Compare before adopting

Before committing, compare this skill against alternatives. Check the quality of the underlying SandBase API: response times, data accuracy, and rate limits. Look at maintenance freshness — is the skill updated when the API changes? Also consider workflow fit: does the skill's tool selection logic match how your agent plans its actions? Finally, weigh it against building your own integrations if you only need one or two lookups.

Why it is worth tracking

With 60 stars and an active author (sandbaseai), this skill shows early community traction. It solves a real pain point — bundling domain OSINT into agent-friendly calls — and its structured workflow aligns with best practices for agent tool use. Track it if you're building security or research agents; it's a strong candidate to fold into your toolkit. For a live listing and updates, see the skill page on OpenAgentSkill. Evaluate it now, and you'll save days of integration work later.
