Test Red Team
Adversarial red-team of a running web, React Native, or Capacitor hybrid app. Drives Playwright browser MCP (web/PWA), Playwright Android WebView attach (Capacitor), or adb tap-walk (native chrome) against a feature-first coverage matrix: each feature decomposed to surfaces, sub-pages, components, and states, attacked across 4 dimensions — UI/UX, data pipeline, security (OWASP-mapped), and performance. Cross-references Sentry for production telemetry, Supabase for DB-layer mutation truth and RLS verification, and Firecrawl for current OWASP/MASVS guidance. Produces a severity-ranked defect list with repro steps and evidence. Generic across any repo and stack. Use when asked to "red team this app", "attack my app", "break it", "find all the defects", "adversarial test", "pre-launch hardening", "pentest the app", or "full app QA". Distinct from test-playwright (session PDCA), test-qa (happy-path crawl), and audit-security (static code review).

From the source SKILL.md
The job is not done when the code compiles or even when the happy path works. It is done when a hostile, skeptical attacker has tried every angle — UI/UX, data pipeline, security, and performance — and the defect list is in the user's hands. This skill exists because nobody ships a perfect first pass. Red teaming finds the gaps before real users do.
What this skill does
Test Red Team is a community-contributed Claude Code skill in the red-team sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/test-red-team/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to "red team this app", "attack my app", "break it", "find all the defects", "adversarial test", "pre-launch hardening", "pentest the app", or "full app QA". Distinct from test-playwright (session PDCA), test-qa (happy-path crawl), and audit-security (static code review).
Who uses this skill
The Test Red Team Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
