hunt-tls-network

Hunt TLS/SSL and DNS misconfigurations — missing HSTS (downgrade attack), weak cipher suites, expired/invalid certificates, mTLS bypass, missing SPF/DKIM/DMARC (email spoofing), DNS Zone Transfer (AXFR), dangling CNAME subdomain takeover, CAA records. Most of these are Info/Low on their own — this skill is opinionated about which findings actually pay (spoofable DMARC with delivered-to-inbox proof, AXFR returning internal hosts, dangling-CNAME takeover) versus which get rejected as best-practice noise (missing CAA, missing HSTS with no MitM position). Use during recon to find infrastructure weaknesses, and to TRIAGE them honestly before reporting.

Content

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-sequenced hunting guide with strong validation gates, weakened mainly by redundancy across its triage sections and the absence of any progressive-disclosure structure for a 354-line body.

Suggestions

De-duplicate the severity/pay-vs-reject guidance: state it once in the Chain Table and have the Reality Check and Validation sections reference it instead of re-listing the same calibrations three times.

Split the per-CVE triage notes (SWEET32/POODLE/FREAK/DROWN) and the Chain Table into a reference file (e.g. references/triage.md) linked from SKILL.md, so the main body stays an overview with one-level-deep navigation.

Tighten explanatory prose around CAA and DMARC receiver-vs-sender behavior to the actionable framing, removing restatements of the same false-positive point across Phase 7 and the Chain Table.

DimensionReasoningScore

Conciseness

Much of the prose is genuinely valuable opinionated triage knowledge Claude would not have calibrated this way, but the same severity calibrations and pay/no-pay lists are repeated across the Reality Check, Chain Table, and Validation sections, so it could be tightened. Not a 1 because it is not padded with basic concept explanations; not a 3 because of the redundancy and length.

2 / 3

Actionability

Every phase ships copy-paste-ready, executable commands — testssl.sh, sslyze, openssl s_client, dig, curl, swaks, nmap — with concrete flags and grep filters, matching the 'fully executable code/commands; copy-paste ready' anchor.

3 / 3

Workflow Clarity

Eight clearly sequenced phases each carry explicit validation/confirmation gates ('Validation gate — a takeover claim requires...', 'Confirmation gate — a spoof PoC is only valid if...') and teardown instructions, providing the feedback loops the rubric rewards for risky operations.

3 / 3

Progressive Disclosure

Sectioning into phases is clear, but the skill is a 354-line monolith with no bundle files and no one-level-deep references; the Chain Table and per-CVE triage notes are content that could live in a separate reference but is inline. Not a 1 because organization is good, not a 3 because there is no progressive disclosure structure and it far exceeds the under-50-line simple-skill allowance.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that names concrete finding types, includes natural trigger terms, gives an explicit use-when clause, and occupies a distinct niche. Voice is third-person/imperative with no first/second-person slippage.

DimensionReasoningScore

Specificity

Enumerates many concrete, specific finding types — 'missing HSTS (downgrade attack), weak cipher suites, expired/invalid certificates, mTLS bypass, missing SPF/DKIM/DMARC (email spoofing), DNS Zone Transfer (AXFR), dangling CNAME subdomain takeover, CAA records' — matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

Explicitly answers both what ('Hunt TLS/SSL and DNS misconfigurations ...') and when ('Use during recon to find infrastructure weaknesses, and to TRIAGE them honestly before reporting'), satisfying the explicit-trigger requirement that would otherwise cap completeness at 2.

3 / 3

Trigger Term Quality

Dense with natural recon terms a user would actually say — 'TLS/SSL', 'DNS', 'HSTS', 'SPF/DKIM/DMARC', 'email spoofing', 'AXFR', 'subdomain takeover', 'recon' — giving good coverage rather than just technical jargon.

3 / 3

Distinctiveness Conflict Risk

Carves a clear, narrow niche (TLS/SSL + DNS misconfiguration triage for bug bounty) with distinct triggers, making it unlikely to fire for unrelated skills.
