Writing or reviewing code that handles untrusted input, secrets, outbound requests, rendered content, or third-party dependencies — "is this safe", "secure by default", "harden", "security", "secret", "privacy", "PII", "XSS", "injection", "SSRF", "safe fetch", "access control", or a dependency review. The OWASP Top 10:2025 lens in two modes, writing secure-by-default code and judging the risk a change introduces. Covers secrets and environment variables, input validation, output encoding, SSRF, access control and data exposure, and supply-chain risk.
Application security covering threat modeling (STRIDE), OWASP Top 10 (2025), OWASP API Security Top 10 (2023), secure coding review, authentication/authorization patterns, input validation, encryption, security headers, supply chain security, compliance (GDPR/HIPAA/SOC2/PCI-DSS), and security monitoring. Use when reviewing code for vulnerabilities, implementing auth patterns, securing APIs, configuring security headers, hardening supply chain, preventing injection attacks, or preparing for compliance audits.
Application security testing (AppSec) across a whole product with Strix — decide which asset needs which test (source code, running web app, API, CI pipeline), run it, and turn the results into a ranked remediation plan. Autonomous agents exploit and prove each issue instead of emitting static-analysis alerts, so the plan is ordered by what is actually reachable. Use when the user asks for an application security review or audit, an appsec assessment, vulnerability scanning across their stack, a security review before a launch or a customer security questionnaire, or does not yet know which kind of security test they need.
Modelar ameaças e revisar segurança de aplicações, APIs, autenticação, autorização, dados, dependências, secrets e infraestrutura. Use para mudanças com trust boundaries, identidade, entrada externa, dados sensíveis ou revisão de segurança; use também para threat modeling antes de uma feature com nova superfície de ataque; não declare segurança sem evidência, e para hardening de pipeline/credenciais de deploy use `$specsfy-specialist-delivery-engineering`.
Hardens code against vulnerabilities. Use when handling user input, authentication, data storage, or external integrations. Use when building any feature that accepts untrusted data, manages user sessions, or interacts with third-party services.
Implement security best practices for web applications and infrastructure. Use when securing APIs, preventing common vulnerabilities, or implementing security policies. Handles HTTPS, CORS, XSS, SQL Injection, CSRF, rate limiting, and OWASP Top 10.
Security guidelines for LLM applications based on OWASP Top 10 for LLM 2025. Use when building LLM apps, reviewing AI security, implementing RAG systems, or asking about LLM vulnerabilities like "prompt injection" or "check LLM security".
Comprehensive SecOps skill for application security, vulnerability management, compliance, and secure development practices. Includes security scanning, vulnerability assessment, compliance checking, and security automation. Use when implementing security controls, conducting security audits, responding to vulnerabilities, or ensuring compliance requirements.
Expert at securing web applications against OWASP Top 10 vulnerabilities. Covers authentication, authorization, input validation, XSS prevention, CSRF protection, secure headers, and security testing. Treats security as a first-class requirement, not an afterthought. Use when "security, OWASP, XSS, CSRF, SQL injection, authentication security, authorization, input validation, secure headers, vulnerability, penetration testing, security, owasp, authentication, authorization, xss, csrf, injection, headers" mentioned.
Race condition and TOCTOU testing for web apps. Use when testing one-time operations, concurrent HTTP abuse, rate-limit bypass, Turbo Intruder gates, HTTP/2 single-packet attacks, and CWE-362-style synchronization gaps.
Run an AWS Security Agent penetration test against a live web application — registers and verifies the target domain, exercises the supplied endpoints with the managed Security Agent service, and returns verified runtime findings. Use when the user asks to pentest, run a penetration test, test their app's attack surface, find runtime vulnerabilities, register or verify a target domain, or check pentest status / findings.
Create security policies, guidelines, compliance documentation, and security best practices. Use when documenting security policies, compliance requirements, or security guidelines.
