Perform a comprehensive code security review against the 2025 MITRE CWE Top 25 Most Dangerous Software Weaknesses (sourced from https://cwe.mitre.org/top25/). Use this skill every time the user asks for a code security review, security audit, vulnerability scan, CWE review, secure code review, source review, or any variant of "check my code for security issues". This skill runs 25 dedicated analysis passes -- one per CWE in the Top 25 -- each focused on finding ALL instances of its assigned weakness across the entire codebase. Results are risk-ranked from highest to lowest and every finding includes a specific, actionable remediation recommendation grounded in good software security engineering practice and principles.

Build type-safe global state in React with Zustand. Supports TypeScript, persist middleware, devtools, slices pattern, and Next.js SSR with hydration handling. Prevents 6 documented errors. Use when setting up React state, migrating from Redux/Context, or troubleshooting hydration errors, TypeScript inference, infinite render loops, or persist race conditions.

Extracts Mermaid diagrams from markdown files and generates high-quality PNG images using bundled scripts. Activates when working with Mermaid diagrams, converting diagrams to PNG, extracting diagrams from markdown, or processing markdown files with embedded Mermaid code.

Runs load tests, profiles application bottlenecks, analyzes response time metrics, and generates performance optimization recommendations. Use when you need to benchmark a system, run load or stress tests, measure latency or throughput, identify performance bottlenecks, optimize Core Web Vitals (LCP, FID, CLS), plan capacity, enforce performance budgets in CI/CD pipelines, or investigate slow API response times, database query performance, or frontend rendering delays.

Use this skill when working with symbolic mathematics in Python. This skill should be used for symbolic computation tasks including solving equations algebraically, performing calculus operations (derivatives, integrals, limits), manipulating algebraic expressions, working with matrices symbolically, physics calculations, number theory problems, geometry computations, and generating executable code from mathematical expressions. Apply this skill when the user needs exact symbolic results rather than numerical approximations, or when working with mathematical formulas that contain variables and parameters.
