huawei-cloud-cdn-dns-resolution-diagnosis

huawei-cloud-cdn-dns-resolution-diagnosis is a skill for Claude Code, Codex from huaweicloud/huaweicloud-skills. It costs 279 tokens per session (6,651 once invoked), scanned B, original, MIT.

A diagnostic helper for checking whether a domain’s DNS records point correctly to Huawei Cloud CDN. DNS is the system that turns a domain name into network addresses; the helper checks the expected CNAME, resolved IPs, and IP ownership.

In plain words
What is it for?
Use it to retrieve the expected CDN target, test DNS resolution, verify returned IP addresses, and produce a diagnosis with suggested corrections.
Why use it?
It helps distinguish a wrong DNS setting, an update that has not taken effect, and a partial or misleading resolution result.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • medium Excessive Agency · line 242
    Skill grants unrestricted tool access without appropriate constraints. An agent with unfettered tool access can perform arbitrary actions including file modification, network requests, and code execution.
    Fix: Restrict tool access to only the tools required for the skill's stated purpose. Use an explicit allowlist rather than granting blanket access.
  • low Privilege Escalation · line 270
    Skill requests more permissions than appear necessary for its stated functionality. Review if elevated access is justified.
    Fix: Request only the minimum permissions required. Document why each permission is needed. Remove broad permissions like '*' or 'all'.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

huawei-cloud-cdn-dns-resolution-diagnosis scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/dns_resolve.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

CDN DNS Resolution Diagnosis

Overview

This skill diagnoses CDN domain DNS resolution issues. It queries the CDN domain detail via hcloud CLI to obtain the expected CNAME, probes the actual DNS resolution of the domain via scripts/dns_resolve.py (dnspython) to collect the IP list, and verifies the IP attribution via ShowIpInfo/v2 to determine whether the domain has been correctly resolved to Huawei Cloud CDN, helping users identify the root cause of DNS configuration anomalies, resolution not taking effect, false positives, and other issues.

Key Features:

  • Domain permission validation and CNAME retrieval (ShowDomainDetailByName)
  • DNS resolution probing to obtain the IP list (python scripts/dns_resolve.py, JSON output with data.resolved_ips inside the {result, data, error_msg} envelope)
  • IP attribution check (ShowIpInfo/v2, up to 20 IPs)
  • False positive identification (partial resolution scenarios prompt multi-region probing)
  • Structured diagnosis report with remediation suggestions

Tools: hcloud CLI (KooCLI) + python scripts/dns_resolve.py (dnspython >= 2.1) Probe Timeout: 10 seconds (enforced by dns_resolve.py --timeout 10) IP Query Limit: 20 IPs Core Principle: Read-only diagnosis, no configuration changes

Scope

In scope: This skill diagnoses only DNS resolution issues for CDN domains, including:

  • Validating that the domain belongs to the current account and retrieving the expected CNAME (ShowDomainDetailByName)
  • Probing the actual A-record resolution of the domain (python scripts/dns_resolve.py, dnspython)
  • Verifying whether the resolved IPs belong to Huawei Cloud CDN (ShowIpInfo/v2, up to 20 IPs per call)
  • Detecting "partial resolution / false positive" scenarios and producing a structured diagnosis report with remediation suggestions

Out of scope:

  • ❌ No write/modify/delete operations (this skill is read-only; see the 55 prohibited operations in ⛔ Prohibited Operations)
  • ❌ No DNS record changes, no CDN configuration changes, no cache refresh/preheat
  • ❌ No diagnosis of other directions: HTTPS certificate, origin-pull failures, domain ownership verification (hand off via the Related Skills section)
  • ❌ No handling of requests that require configuration changes (refuse and direct the user to the console or manual hcloud CLI usage)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
