command-injection-anti-pattern
by igbuend
"Security anti-pattern for OS Command Injection vulnerabilities (CWE-78). Use when generating or reviewing code that executes shell commands, runs system processes, or handles user input in command-line operations. Detects shell string concatenation and recommends argument arrays."
mass-assignment-anti-pattern
by igbuend
"Security anti-pattern for mass assignment vulnerabilities (CWE-915). Use when generating or reviewing code that creates or updates objects from user input, form handling, or API request processing. Detects uncontrolled property binding enabling privilege escalation."
security-review
by dstiliadis
Mandatory security review gate for all code and architecture plans. Triggers on ANY plan, implementation, code generation, architecture design, API design, infrastructure change, deployment configuration, or system modification. Before executing or finalizing ANY plan that produces code, configuration, or infrastructure, run the full security review workflow: threat model, review against security checklist, emulate attack paths agentically, mitigate findings, and pen-test again before delivery. This skill acts as a security-conscious intern with CompTIA Security+ knowledge who reviews every output for authentication, authorization, encryption, logging, input validation, segmentation, privacy, and common vulnerability anti-patterns. Also triggers when the user asks to "review security", "threat model", "harden", "pen test", or "check for vulnerabilities".
codebase-discovery
by igbuend
Generate security-focused DISCOVERY.md for code review and threat modeling. Use when assessing unfamiliar codebases.
attack-surface-xss
by igbuend
Reconnaissance skill for XSS attack surface — analyzes headers, frameworks, JS libraries, and DOM patterns at a URL to map what makes XSS possible or harder. For ethical hackers preparing for XSS testing.
insecure-temp-files-anti-pattern
by igbuend
"Security anti-pattern for insecure temporary files (CWE-377). Use when generating or reviewing code that creates temporary files, handles file caching, or processes uploads through temp storage. Detects predictable paths, insecure permissions, and missing cleanup."
insecure-defaults-anti-pattern
by igbuend
Security anti-pattern for fail-open defaults (CWE-1188). Use when reviewing code that uses fallback values for secrets, credentials, or security settings. Detects applications that run with weak defaults when configuration is missing.
missing-authentication-anti-pattern
by igbuend
"Security anti-pattern for missing or broken authentication (CWE-287). Use when generating or reviewing code for login systems, API endpoints, protected routes, or access control. Detects unprotected endpoints, weak password policies, and missing rate limiting on authentication."
mutation-xss-anti-pattern
by igbuend
"Security anti-pattern for mutation XSS (mXSS) vulnerabilities (CWE-79 variant). Use when generating or reviewing code that sanitizes HTML content, handles user-provided markup, or processes rich text. Detects sanitizer bypass through browser parsing mutations."
missing-input-validation-anti-pattern
by igbuend
"Security anti-pattern for missing input validation (CWE-20). Use when generating or reviewing code that processes user input, form data, API parameters, or external data. Detects client-only validation, missing type checks, and absent length limits. Foundation vulnerability enabling most attack classes."
missing-rate-limiting-anti-pattern
by igbuend
"Security anti-pattern for missing rate limiting (CWE-770). Use when generating or reviewing API endpoints, authentication systems, or public-facing services. Detects absence of request throttling enabling brute force, credential stuffing, and DoS attacks."
log-entity-actions-pattern
by igbuend
Security pattern for implementing security logging and audit trails. Use when designing logging systems for security events, implementing non-repudiation, creating audit trails, or addressing security monitoring and incident response needs. Addresses "Entity repudiates action request" problem.
code-reviewer
by 9tykeshav
Use when asked to review MERN stack code - comprehensive code reviewer that checks project health, security, maintainability, performance, testing, and architecture. Combines general code quality analysis with MERN-specific expertise.
ldap-injection-anti-pattern
by igbuend
"Security anti-pattern for LDAP injection vulnerabilities (CWE-90). Use when generating or reviewing code that constructs LDAP filters, queries directory services, or handles user input in LDAP operations. Detects unescaped special characters in LDAP filters."
insufficient-randomness-anti-pattern
by igbuend
"Security anti-pattern for insufficient randomness vulnerabilities (CWE-330). Use when generating or reviewing code that creates security tokens, session IDs, encryption keys, nonces, or any security-critical random values. Detects use of Math.random() or predictable seeds."
message-authentication-code-pattern
by igbuend
Security pattern for implementing Message Authentication Codes (MACs) to ensure data integrity and origin authentication. Use when implementing HMAC, CMAC, or other MAC algorithms, verifying message integrity, authenticating message origin with shared secrets, or when non-repudiation is NOT required. Specialization of Cryptographic action pattern.
application-inspector
by igbuend
Run Microsoft Application Inspector for technology profiling and security feature detection. Use when analyzing technology stack, finding crypto/auth patterns, detecting sensitive API usage, or creating security posture reports.
