Skill UI

A comprehensive guide to exploiting PHP's loose type checking (using '==') and type juggling mechanics. This skill is crucial for bypassing security controls like authentication checks, HMAC/signature validations, and token comparisons that fail to use strictly typed comparisons (===) or timing-safe functions (hash_equals). Includes techniques for magic hash collisions and PHP version delta analysis.

A comprehensive, expert-level guideline for building Agentic User Interfaces (UIs). This system emphasizes conversational interactions, clear outcomes, and minimal user controls, allowing users to delegate complex tasks to AI. It provides structured rules covering color tokens, typography, accessibility (WCAG 2.2 AA), and component anatomy for professional developers and designers.

A comprehensive guide for securing container images and runtime environments. Covers best practices from Dockerfile authoring (minimal base images, multi-stage builds, non-root users) through advanced runtime enforcement (seccomp, AppArmor) and Kubernetes security controls. Essential for production hardening and maintaining supply chain integrity.

This skill provides comprehensive management for Opencode's permission system. It allows users to review currently always-allowed commands, suggest safe read-only commands, and configure granular access controls using allow/deny/ask patterns. It is essential for optimizing security, performing system audits, and managing the operational scope of the agent.

This skill maps engineering changes (code diffs, architecture designs, IaC) to specific financial compliance controls, such as PCI-DSS v4.0 and MAS TRM. It generates an auditable report detailing compliance gaps, required evidence, and concrete remediation steps, helping teams catch violations before formal audits.

This skill generates a comprehensive, structured threat model for any given service or feature using the STRIDE framework. It guides users through identifying critical assets, defining trust boundaries, enumerating specific threats (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege), assessing risk, and proposing concrete mitigation controls. Ideal for security design reviews and documentation.

A comprehensive guide for defense contractors handling Controlled Unclassified Information (CUI). It covers preparing for CMMC Level 2 certification, implementing 110 NIST SP 800-171 controls, calculating the SPRS score using DoD methodology, and managing the POA&M and SSP. Essential for DFARS compliance and external assessments.

This skill deploys Remote Browser Isolation (RBI) as a core component of a Zero Trust security architecture. It implements sophisticated isolation policies utilizing URL categorization, risk-based routing, and Content Disarming and Reconstruction (CDR) for file sanitization. It provides robust data loss prevention controls, effectively mitigating zero-day exploits, phishing, and data exfiltration across isolated web sessions, and integrating with SWG and ZTNA platforms.

This skill guides the comprehensive hardening of LDAP directory services. It addresses common vulnerabilities such as LDAP injection, anonymous binding, and credential harvesting. Users can enforce strong security controls, including LDAPS, channel binding, and granular access control lists (ACLs). It is essential when establishing robust identity access management (IAM) architecture or meeting stringent compliance requirements like NIST standards.

Business Email Compromise (BEC) is a sophisticated fraud scheme relying on social engineering. This skill provides comprehensive guidance on detecting and mitigating BEC attacks. It covers using email gateway rules, behavioral analytics, and implementing financial controls to identify impersonation attempts, altered payment details, and urgent fraudulent requests.

This skill details the implementation of continuous identity verification for Zero Trust architectures. It covers deploying phishing-resistant Multi-Factor Authentication (FIDO2/WebAuthn), establishing risk-based conditional access policies, and integrating identity governance controls aligned with NIST and CISA frameworks. Learn how to move beyond traditional passwords to dynamic, adaptive security models.

A comprehensive guide for conducting authorized vishing (voice phishing) pretext calls. This technique, utilized in red-teaming, simulates an attacker impersonating a trusted authority (e.g., IT support, vendor) to test an organization's human security controls. It measures employee adherence to verification protocols and highlights vulnerabilities in staff security awareness.
