Three tools over the hosted DNS Doctor API (dnsdoctor.dev): the full SPF/DKIM/DMARC/MX/DNS/blacklist/expiry report with copy-paste fix records from a validating engine, the next safe DMARC record, and a six-location propagation check. No API key needed; responses relayed verbatim; transport failures returned as text that says they are not a verdict. Uses the existing requests dependency; unit tests mock the network.

Inline comments:
In `@lib/crewai-tools/src/crewai_tools/tools/dns_doctor_tool/dns_doctor_tool.py`:
- Around line 174-175: Update the expected_value handling in the DNS doctor
request construction to include the field whenever expected_value is not None,
preserving an explicitly provided empty string while still omitting the field
when no value was supplied.
- Line 82: Update the DNS doctor tool’s response handling to validate the
payload with response.json() but return the original response.text unchanged
instead of serializing it with json.dumps(). Preserve the existing validation
flow and verbatim JSON relay behavior.
In `@lib/crewai-tools/tests/tools/dns_doctor_tool_test.py`:
- Line 30: Update the DNS doctor tool tests around the shared _call behavior to
use a deliberately distinct response.text value and assert the returned out
string equals response.text directly, rather than only comparing json.loads(out)
with REPORT. Apply the same raw-text assertion to the additional test location
so the tests verify verbatim response relay.
- Line 32: Update the endpoint tests around _call and the assertions at lines
32, 44, and 50 to explicitly set DNSDOCTOR_API_BASE to https://dnsdoctor.dev or
remove it with monkeypatch before each test, ensuring runtime environment
overrides cannot affect the expected default URLs.

Summary
Adds three tools over the hosted DNS Doctor API to
lib/crewai-tools, giving agents deterministic DNS and email-authentication checks for a domain:DnsDoctorScanTool: the full report (SPF, DKIM, DMARC, MX, DNS health, blacklists, domain and TLS expiry) with per-check verdicts and copy-paste fix records from a validating engine, never a model-generated record.DnsDoctorDmarcUpgradeTool: the next safe DMARC record for a domain, alignment-gated, with the rationale.DnsDoctorPropagationTool: whether a DNS change has propagated, read from six locations on four continents.No API key is needed (an optional
DNSDOCTOR_API_TOKENraises the rate limit). Uses the existingrequestsdependency, no new extras. Responses are relayed verbatim as JSON text; transport failures (rate limit, 5xx, network) are returned as text that says they are not a verdict about the domain. A402relays the x402 payment offer so an x402-capable caller can pay and retry.Checklist
