vulnerability-scanner

vulnerability-scanner is a skill for Claude Code, Codex from bugrabilge/bilge-development-kit. It costs 27 tokens per session (1,851 once invoked), scanned A, original, MIT.

A security review guide for finding weaknesses in source code, running application checks, auditing third-party packages, and tracking known security issues.

In plain words
What is it for?
Use it to review code and dependencies, investigate CVEs (public records of known vulnerabilities), add security checks to CI/CD (automated build and deployment pipelines), and prepare compliance checks.
Why use it?
It helps reveal security problems before attackers or production users find them, and helps turn findings into fixes and automated checks.

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 A, and why

vulnerability-scanner scanned grade A with 0 findings 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vulnerability Scanner

"Security is not a product, but a process." -- Bruce Schneier

When to Use

  • Scanning code for security vulnerabilities (SAST)
  • Running dynamic application security testing (DAST)
  • Auditing dependencies for known vulnerabilities (SCA)
  • Tracking and prioritizing CVEs affecting your software
  • Implementing automated security checks in CI/CD pipelines
  • Developing remediation plans for discovered vulnerabilities
  • Performing compliance checks (SOC 2, PCI DSS, HIPAA)

Vulnerability Scanning Categories

SAST (Static Application Security Testing)

Analyzes source code without executing it. Catches vulnerabilities early in development.

Tools:

  • Semgrep: Rule-based, fast, supports 30+ languages, community rules
  • SonarQube/SonarCloud: Comprehensive code quality and security analysis
  • CodeQL (GitHub): Deep semantic code analysis, built into GitHub Advanced Security
  • Bandit: Python-specific security linter
  • Brakeman: Ruby on Rails security scanner
  • ESLint security plugins: eslint-plugin-security, eslint-plugin-no-unsanitized

What SAST catches:

  • SQL injection patterns
  • Cross-site scripting (XSS) sinks
  • Hardcoded secrets and credentials
  • Insecure cryptographic usage
  • Path traversal vulnerabilities
  • Command injection
  • Deserialization flaws

DAST (Dynamic Application Security Testing)

Tests a running application by sending crafted requests. Finds runtime vulnerabilities.

Tools:

  • OWASP ZAP: Open-source, full-featured web app scanner
  • Burp Suite: Professional-grade web security testing
  • Nuclei: Template-based vulnerability scanner, fast and extensible
  • Nikto: Web server scanner for misconfigurations
  • DAST in CI: Use ZAP baseline scan or Nuclei in pipelines

What DAST catches:

  • Authentication and session management flaws
  • Server misconfigurations
  • Missing security headers
  • CORS misconfigurations
  • Exposed sensitive endpoints
  • Runtime injection vulnerabilities

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-scanner is a skill published in the GitHub repository bugrabilge/bilge-development-kit (10 stars, last pushed 4mo ago), licensed MIT. It adds 27 tokens to every session and 1,851 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
