domain_report

Read-onlyIdempotent

Query DNS, WHOIS, SSL, subdomains, and threat intelligence for a domain in a single API call. Returns a comprehensive report with risk score, email security config, and recommended next steps.

Instructions

Query DNS, WHOIS, SSL, subdomains, and threat intel for a domain in one call. By default dns.txt is filtered to security-relevant entries (SPF, DMARC, DKIM, MTA-STS, TLS-RPT) and dns.total_txt_records reports the honest pre-filter count; pass include_all_txt=true for the raw TXT list. Use as a starting point for domain investigations; use audit_domain for live headers + tech stack. Response carries next_calls — chain with subdomain_enum (always emitted), ssl_check + tech_fingerprint (when an A record resolves) for the standard recon depth without re-prompting. Free: 30/hr, Pro: 500/hr. Returns domain report with DNS records, WHOIS data, SSL cert, risk score, email config, threat status, recommendation, and next_calls.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
domainYesRoot domain to analyze, without protocol or path (e.g. 'example.com', 'shopify.com')
include_all_txtNoReturn every TXT record (default: False, only SPF/DMARC/DKIM/MTA-STS/TLS-RPT kept). dns.total_txt_records is always emitted with the honest pre-filter count. Default filter strips vendor verification strings (google-site-verification, ms=, facebook-domain-verification, etc.) that bloat the response without security signal. Set True only when you need the raw TXT inventory.

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Discloses default TXT filtering behavior, pre-filter count reporting, and next_calls emission. Annotations (readOnlyHint, idempotentHint) are consistent and description adds significant behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Concise yet informative description. Front-loaded with main function, then details on parameters, usage, and output. Every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (multiple data sources), the description covers return contents, chaining, and rate limits. Output schema exists for return values, so complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% coverage with clear descriptions. Description adds extra value by explaining the reasoning behind TXT filtering and when to set include_all_txt=true, but schema already provides good semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool queries DNS, WHOIS, SSL, subdomains, and threat intel for a domain. It distinguishes itself from sibling tools like audit_domain by noting it is a starting point.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance: use as starting point, use audit_domain for live headers, and chain with subdomain_enum, ssl_check, tech_fingerprint. Also mentions rate limits (30/hr free, 500/hr Pro).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
