Implement comprehensive security patterns to protect applications against OWASP Top 10 vulnerabilities including XSS, CSRF, SQL injection, authentication bypass, and data exposure. Use when handling user data, implementing authentication and authorization, validating input, encrypting sensitive data, preventing injection attacks, securing API endpoints, managing sessions and tokens, implementing rate limiting, configuring security headers, or building security-critical features that require defense-in-depth protection.

Generate measurable learning outcomes aligned with Bloom's taxonomy and CEFR proficiency levels for educational content.Use this skill when educators need to define what students will achieve, create learning objectivesfor curriculum planning, or ensure objectives are specific and testable rather than vague.This skill helps break down complex topics into progressively building learning goals with clearassessment methods and success criteria.

Plan, structure, and scaffold large educational books using cognitive load management,just-in-time specification, and pedagogical best practices. Use this skill when planningmulti-part, multi-chapter educational works that require narrative continuity, progressivecomplexity, and hands-on exercises. This skill helps create cohesive learning journeysthat balance foundational scaffolding with advanced independence. Activate when tasksinvolve structuring books, managing cognitive load across chapters, defining part-levelnarratives, or coordinating multi-phase content development workflows.
