Install and run

Setup complexity: low.

clawhub skill install s176561hhmg2fa269fhhrhxz6h8bb36n:dns-doctor
  1. Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
  2. Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

# DNS Doctor: scan, fix and verify a domain's DNS

DNS Doctor scans, fixes and verifies a domain's DNS — email authentication (SPF,
DMARC, DKIM) first, plus multi-region propagation, SPF include supply-chain
audits, MX, DNS health, blacklists and domain/SSL expiry — and returns
**deterministic verdicts** plus **copy-paste fix records generated by a
validating engine**. The record you get back is verified against RFC grammar and
the SPF 10-lookup limit — it is never an LLM guess. Your job is to run the scan,
explain the findings, hand the human the exact record, and confirm the fix — not
to author DNS records yourself.

## What this skill sends, and where

Every command below talks to one host, `https://dnsdoctor.dev`, over HTTPS. What
leaves the machine is exactly what the user asked to check: a domain name, and
for the focused checks a record name, an IP address, a DKIM selector, or a DMARC
record the user pasted. The look-alike check sends only the domain the user asked
about; the look-alike names are generated and checked on our side. Nothing else
is read or sent — no files, no environment beyond the optional
`DNSDOCTOR_API_TOKEN`, no message contents.

Two things the user should know before you run a scan for them:

- **A scan result is a public report page** at `https://dnsdoctor.dev/scan/<domain>`
  (the free scanner is a public service, like a DNS lookup site). Do not scan a
  domain the user wants kept private, and say so if they ask.
- **The optional API token** (`DNSDOCTOR_API_TOKEN`) is sent only to the three
  monitoring reads under `/api/v1/alerts`, `/api/v1/readiness` and
  `/api/v1/lookalikes`, only as an `Authorization` header, and only if the user
  put it in your environment. Never send any other credential, and never ask for
  one.

DNS Doctor never changes DNS: it returns records for a human to publish.

## When to use this skill

Reach for it whenever a user describes any of:

- "our email is going to spam" / "customers aren't getting our mail"
- "SPF PermError" or "too many DNS lookups" (the SPF 10-lookup limit)
- "DMARC is stuck at p=none" / "how do I get to p=

## Description:

Helps agents diagnose DNS and email authentication issues, explain validated findings, and present DNS records for a person to publish and verify.

This skill is ready for commercial/non-commercial use.

## Publisher:

[dnsdoctor](https://clawhub.ai/user/dnsdoctor)

### License/Terms of Use:

MIT-0

## Use Case:

Domain owners, mail administrators, and developers use this skill to investigate delivery and DNS health, review suggested records, and confirm changes after publishing them themselves.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Domains and DNS records submitted for checks leave the user's environment, and scan results are public.

Mitigation: Confirm the user is comfortable sharing the domain and avoid scanning domains that must remain private.

Risk: Account-specific monitoring reads use an optional API token.

Mitigation: Only use a token the user has set in DNSDOCTOR_API_TOKEN; do not request or disclose credentials.

Risk: Calls beyond the free limit may prompt for x402 payment.

Mitigation: Review any payment prompt with the user before authorizing a paid call.

## Skill Output:

**Output Type(s):** [Analysis, Markdown, Shell commands, Configuration guidance]

**Output Format:** [Markdown with diagnostic findings and verbatim DNS record suggestions]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [DNS changes require human publication; scans may produce public report pages.]

## Skill Version(s):

1.10.1 (source: ClawHub release metadata)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
