Agent-skills is a collection of structured instructions and behavioral personas designed to standardize how AI coding agents perform engineering tasks. It functions as a workflow orchestrator that maps natural language intent to repeatable technical sequences and verification checklists. The project distinguishes itself through the use of specialized markdown-defined roles, such as security auditors or test engineers, to apply targeted domain expertise. It employs an evidence-based verification model that requires runtime data or passing tests as mandatory exit criteria to ensure AI-generated

Nuclei is a modular security scanning framework designed for automated vulnerability detection and infrastructure reconnaissance. It functions as a template-driven engine that executes security checks across diverse network protocols, allowing users to define custom detection logic to identify vulnerabilities, misconfigurations, and exposed assets. The platform distinguishes itself through its highly extensible architecture, which supports distributed scanning, headless browser automation for dynamic web content, and out-of-band interaction monitoring to detect blind vulnerabilities. It integ

Subfinder is a security reconnaissance framework designed for subdomain enumeration and attack surface management. It functions as a discovery engine that identifies and maps internet-exposed infrastructure, cloud-hosted assets, and network ranges to maintain a comprehensive inventory of an organization's digital footprint. The project distinguishes itself through a modular, template-driven scanning engine that executes security checks against discovered assets. It leverages cloud-native asset discovery to query provider APIs and infrastructure metadata, while supporting distributed agent orc

Gixy is a static configuration analyzer and security auditor for Nginx. It functions as an infrastructure-as-code security scanner and web server configuration linter designed to identify vulnerabilities and misconfigurations in server definitions before deployment. The tool focuses on detecting high-risk security flaws, including host header spoofing, server-side request forgery, and path traversal. It specifically audits Nginx configurations for risks such as HTTP splitting, multiline header issues, and unauthorized third-party access resulting from incorrect Referer or Origin header patter

Brakeman is a static analysis security tool and scanner specifically designed for Ruby on Rails source code. It identifies common security vulnerabilities, such as injection and cross-site scripting, by analyzing the application codebase without executing the application. The tool functions as a security auditor that detects mass assignment risks and template vulnerabilities. It evaluates the final output of rendered views and identifies unrestricted assignment patterns that could allow unauthorized modification of model attributes. The system provides vulnerability management through the us

Naabu is a port scanner library and tool that probes hosts for open ports using SYN, CONNECT, and UDP methods to identify active services. It functions as a Go library for embedding port scanning into programs, and as a standalone tool that accepts targets as hostnames, IP addresses, CIDR ranges, or ASN numbers. The tool discovers live hosts before scanning, filters ports by range or top lists, and can integrate with Nmap for service version detection. The project distinguishes itself through its SYN-based port probing approach that sends TCP SYN packets and analyzes responses without complet
