Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to medium
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 161 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 Excessive Agency · line 141 Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.Fix: Limit the skill's scope to its documented purpose. Remove instructions that enable the agent to perform actions outside its stated functionality.
- low Privilege Escalation · line 194 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'.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00189 | $0.06202 |
| Opus 5.5 | $0.00076 | $0.02481 |
| Sonnet 5.5 | $0.00038 | $0.01240 |
| Haiku 4.5 | $0.00019 | $0.00620 |
Grade B, and why
huawei-cloud-cdn-traffic-anomaly-analysis 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 28d ago.
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 Traffic Anomaly Analysis
Overview
This skill analyzes CDN domain traffic anomalies by querying billing mode and corresponding traffic/bandwidth metrics. It automatically determines the appropriate metric based on the account's billing mode (bw_95, flux, combine_flux, bw, bw_peak), queries historical data over a configurable time range, establishes a 3-month baseline for comparison, and identifies potential traffic theft or abuse using both absolute thresholds and relative baseline deviation.
Key Features:
- Automatic billing mode detection and metric selection
- Support for all billing modes: bw_95, flux, combine_flux, bw, bw_peak
- Domain validation and traffic analysis
- 3-month baseline analysis — detects relative traffic surges against historical norms
- Dual-threshold anomaly detection — absolute thresholds + relative baseline comparison
- Three-tier conclusions: Normal / Watch (relative surge) / Anomalous (absolute threshold exceeded)
- Comprehensive analysis reports with baseline comparison and daily breakdowns
Tool: hcloud CLI (KooCLI)
Timestamp Tool: scripts/cdn_timestamp.py (built-in)
Analysis Scope: Past 7 days for current window (configurable); past 3 months for baseline
Core Principle: Query only the metric corresponding to the billing mode; use API capabilities efficiently to cover both current and baseline windows with minimal API calls
Triggers
Use this skill when the user request matches one of the following patterns (user-level example inputs):
| User Input Example | Trigger Intent |
|---|---|
| "Is example.com's traffic being stolen or abused?" | Traffic theft detection |
| "Analyze whether CDN bandwidth has surged abnormally in the last 7 days" | Bandwidth anomaly analysis |
| "Compare traffic over the past 3 months with the current period for anomalies" | 3-month baseline comparison |
| "Check our account's CDN billing mode and domain list" | Billing mode / domain query |
| "Why is example.com's 95th percentile bandwidth so high?" | 95th percentile bandwidth analysis |
| "traffic anomaly / bandwidth anomaly / CDN traffic analysis" | English triggers |

What this file has done since we first saw it
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.

huawei-cloud-cdn-traffic-anomaly-analysis is a skill published in the GitHub repository huaweicloud/huaweicloud-skills (59 stars, last pushed yesterday), licensed MIT. It adds 189 tokens to every session and 6,202 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
