Run multi-framework threat modeling and vulnerability scanning on source code, APIs, and infrastructure; simulate realistic attacker personas; and generate prioritized remediation plans and security reports.
npx claudepluginhub florianbuetow/claude-code --plugin appsecSpawned after all parallel red team analysis agents complete their work. Merges, deduplicates, cross-references, and ranks findings from multiple agents into a single consolidated security report with attack chains and prioritized remediation order.
Simulates an ideologically motivated medium-skill attacker seeking maximum public embarrassment through data leaks, defacement, and service disruption
Simulates a malicious authenticated user with domain knowledge who attempts privilege escalation, data exfiltration, and persistent backdoor access using legitimate credentials
Spawned during red team analysis when critical infrastructure or high-value targets are assessed. Simulates an Advanced Persistent Threat actor with unlimited time, resources, and sophistication who chains multiple weaknesses together to achieve persistent access, covert exfiltration, and lateral movement across system boundaries.
Simulates a professional criminal operation with high technical skill seeking financial gain through payment data interception, credential harvesting, PII theft, and ransomware deployment vectors
This skill should be used when the user asks to "check for access control issues", "analyze authorization", "find IDOR vulnerabilities", "audit CORS configuration", "check for privilege escalation", or mentions "access control", "authorization", "IDOR", "CORS", "JWT tampering", or "directory traversal" in a security context. Maps to OWASP Top 10 2021 A01: Broken Access Control.
This skill should be used when the user asks to "check API security", "audit REST API", "find BOLA vulnerabilities", "check for mass assignment", "analyze API rate limiting", "detect excessive data exposure", or mentions "API security", "BOLA", "IDOR", "mass assignment", "rate limiting", "broken function-level authorization", "excessive data exposure", or "OWASP API Top 10" in a security context.
This skill should be used when the user asks to "map attack surface", "list entry points", "inventory API endpoints", "find all inputs", "enumerate routes", "discover exposed endpoints", or "map external interfaces". Also triggers when the user asks about exposed APIs, form handlers, file upload endpoints, WebSocket handlers, CLI argument parsers, or wants to understand where external data enters the system.
This skill should be used when the user asks to "check for authentication issues", "analyze auth", "find credential vulnerabilities", "review login security", "check session management", or mentions "authentication", "passwords", "MFA", "sessions", or "brute force" in a security context. Maps to OWASP Top 10 2021 A07: Identification and Authentication Failures.
This skill should be used when the user asks to "check business logic security", "find logic flaws", "audit workflow security", "check for coupon abuse", "detect negative amount exploits", "analyze state machine security", or mentions "business logic", "workflow bypass", "negative amount", "coupon abuse", "self-referral", "state manipulation", or "time-based exploit" in a security context.

Harness-native ECC plugin for engineering teams - 64 agents, 262 skills, 84 legacy command shims, reusable hooks, rules, MCP conventions, and operator workflows for Claude Code plus adjacent agent harnesses
Analyze Claude Code session logs to identify what went well, what didn't, and how to improve developer-AI collaboration. Suggests new skills, subagents, slash commands, hooks, and workflow optimizations based on actual usage patterns.
Scan a software repository for ISO 27001:2022 compliance of its software development controls (Annex A 8.4, 8.25–8.33). Produces a per-control compliance gap report covering source code access, secure SDLC, application security requirements, secure architecture, secure coding, security testing, outsourced development, environment separation, change management, and test data.
Keep the Anthropic prompt cache warm during Claude Code sessions — especially during peak hours when usage limits are tighter. Detects your cache TTL (5-min default or 1-hour extended) and schedules pings accordingly, reducing token costs by up to 90% on cached context.
Generate and maintain CHANGELOG.md files from git commit history using Keep a Changelog format with semantic versioning. Creates new changelogs or appends updates to existing ones.
Project onboarding skill that orients AI agents by gathering context from project instructions, git state, issue trackers, and build systems to produce a concise status briefing with suggested next steps.
