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.

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 | $0.00026 | $0.03144 |
| Opus 5 | $0.00013 | $0.01572 |
| Sonnet 5 | $0.00005 | $0.00629 |
| Haiku 4.5 | $0.00003 | $0.00314 |
Grade A, and why
Vulnerability Scanning & Assessment scanned grade A 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 7d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
[ ] USER — Must not run as root; add non-root user Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
How it starts
The opening of the file, as written. The whole thing — 321 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Vulnerability Scanning & Assessment
Purpose
Enable Claude to perform comprehensive vulnerability assessments by directly analyzing dependency files, configuration files, and scan output — then generating prioritized, actionable reports. Claude identifies vulnerabilities, calculates risk, and prescribes remediation with version specifics.
Activation Triggers
This skill activates when the user asks about:
- Scanning dependencies for known CVEs
- Auditing
requirements.txt,package.json,go.mod,pom.xml,Cargo.toml - Reviewing server configurations for security issues
- CVSS scoring or severity calculation
- Vulnerability assessment or security audit reports
- Checking software versions against known exploits
- Configuration hardening for nginx, Apache, SSH, Docker, Kubernetes
- NVD, OSV, or CVE database queries
Prerequisites
pip install requests packaging jinja2 pyyaml
Optional enhanced tools:
nuclei— Template-based vulnerability scannertrivy— Container and filesystem scannernmapwith NSE scripts — Network vuln scanningopenvas— Full vulnerability management
Core Capabilities
1. Dependency Vulnerability Auditing
Claude can directly read and analyze dependency files:
When the user asks to audit dependencies:
- Read the dependency file using Claude's Read tool or ask the user to paste it
- Identify package manager from file format:
requirements.txt/Pipfile.lock/pyproject.toml→ Python/pippackage.json/package-lock.json/yarn.lock→ Node.js/npmgo.mod/go.sum→ Go modulespom.xml/build.gradle→ Java/Maven/GradleCargo.toml/Cargo.lock→ Rust/CargoGemfile.lock→ Ruby/Bundlercomposer.lock→ PHP/Composer
- Extract exact versions for all direct and transitive dependencies
- Query vulnerability databases — Claude can search NVD API, OSV, and GitHub Advisory Database for each package+version combination
- Calculate CVSS v3.1 severity for each finding
- Check for available patches — identify the minimum safe version
- Generate prioritized remediation report
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

Vulnerability Scanning & Assessment is a skill published in the GitHub repository Masriyan/Claude-Code-CyberSecurity-Skill (397 stars, last pushed 3d ago), licensed MIT. It adds 26 tokens to every session and 3,144 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
absolute-audit
Vulnerability and security scan (defensive, your own repo): dependency CVEs plus risky code patterns (secrets, injection, weak authz), severity x reachability triaged and remediated without suppressing. Complements the built-in /security-review. Triggers on "absolute audit", "security audit", "are we vulnerable"…
security-review
Scan code changes for security vulnerabilities using STRIDE threat modeling, validate findings for exploitability, and output structured results for downstream patch generation. Supports PR review, scheduled scans, and full repository audits.
vulnerability-scanner
A security scanner that checks software dependencies for known vulnerabilities, analyzes whether they can be reached, creates a software bill of materials, and audits licenses.
audit
A guide to Linux security auditing, which records selected system and user actions for investigation and compliance checks. It uses auditd, Linux's system auditing service.
pentest
PTES-aligned adversarial security audit for backend, frontend, and mobile applications. Produces a CVSS-scored Hacker Report with verified PoCs and phased remediation.
edgeone skill scanner
A local static scanner that checks agent-skill files for security risks before they are installed or used. Static analysis examines files without running them.
