Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/secondsky/claude-skills --skill vulnerability-scanning- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads vulnerability-scanning automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Vulnerability Scanning
Automate security vulnerability detection across code, dependencies, and containers.
Dependency Scanning
# npm audit
npm audit --audit-level=high
# Snyk
snyk test --severity-threshold=high
# Safety (Python)
safety check --full-report
Container Scanning (Trivy)
# Scan container image
trivy image myapp:latest --severity HIGH,CRITICAL
# Scan filesystem
trivy fs --scanners vuln,secret .

try {

} catch (err) {
// A tool may be missing, exit non-zero, or print non-JSON output (e.g.
// trivy progress text when not on a TTY). Treat that as "no parseable
// result" rather than crashing the scanner.

Best Practices
- Integrate scanning in CI/CD pipeline
- Fail builds on high/critical findings
- Scan dependencies and containers
- Track vulnerabilities over time
- Document accepted false positives
Tools
- Trivy (containers, filesystem)
- Snyk (dependencies, code)
- npm audit / yarn audit

When the user wants to audit, review, or diagnose SEO issues on their site. Also use when the user mentions "SEO audit," "technical SEO," "why am I not ranking," "SEO issues," "on-page SEO," "meta tags review," "SEO health check," "my traffic dropped," "lost rankings," "not showing up in Google," "site isn't ranking," "Google update hit me," "page speed," "core web vitals," "crawl errors," "indexing issues," "stuck on page 2," "striking distance keywords," "title tag rewrite," "low CTR," "local SEO," "Google Business Profile," or "map pack." Use this even if the user just says something vague like "my SEO is bad" or "help with SEO" — start with an audit. For building pages at scale to target keywords, see programmatic-seo. For adding structured data, see schema. For AI search optimization, see ai-seo.
firebase-security-rules-auditor

Use when auditing/reviewing rules, running red-team rule assessments, or scoring against auditor checklists. Don't use for Firebase CLI (login, deploy), Auth, Crashlytics, Remote Config, or database queries.

competitors
coreyhaines31/marketingskills
When the user wants to create competitor comparison or alternative pages for SEO and buyer-facing use. Also use when the user mentions 'alternative page,' 'vs page,' 'competitor comparison,' 'comparison page,' '[Product] vs [Product],' '[Product] alternative,' 'competitive landing pages,' 'how do we compare to X,' 'competitor teardown,' 'audit our competitor pages,' 'are our comparison pages out of date,' or 'competitive asset audit.' Use this for any content that positions your product against competitors. Covers four formats: singular alternative, plural alternatives, you vs competitor, and competitor vs competitor. For auditing existing claims (not researching competitors from scratch, which is competitor-profiling; not technical SEO on these pages, which is seo-audit), use the asset audit here.
