Verify Tetris architecture compliance with coding rules and design patterns. Use when reviewing code, implementing features, refactoring, or validating architectural decisions. Auto-triggers on phrases like "review this code", "check architecture", "is this correct?", "refactor this", or "implement feature". Checks for prohibited patterns (classes, enums, any types, hardcoded strings) and required patterns (functional programming, Result type, proper imports).

Use Elsevier APIs (Scopus search / abstract / author / trends / institution / open access) via simple CLI scripts.

Use this skill when the user wants to increment or bump the project version number. This skill reads the current semantic version, increments it (patch/minor/major), updates package.json, Cargo.toml, and tauri.conf.json, runs cargo check to update Cargo.lock, and commits all changes to git with an appropriate commit message.

Comprehensive Rust development guidelines based on 6 months of code reviews. Use when writing Rust code, debugging Rust issues, or reviewing Rust PRs. Covers error handling, file I/O safety, type safety patterns, performance optimization, common footguns, and fundamental best practices. Perfect for both new and experienced Rust developers working on CLI tools, hooks, or production code.

This skill should be used when the user requests to audit, check, or improve application security by analyzing security headers, cookie configuration, RLS policies, input sanitization, rate limiting, and other security measures. It generates a comprehensive security audit report with actionable recommendations. Trigger terms include security audit, security check, harden security, security review, vulnerability check, security headers, secure cookies, input validation, rate limiting, security best practices.

Master advanced ASP.NET Core development including Entity Framework Core, authentication, testing, and enterprise patterns for production applications.

Generate comprehensive multi-approach strategies before execution. Extract domain knowledge, create alternative approaches, identify failure modes, and develop risk-aware plans. Use proactively for complex tasks requiring strategic thinking or when multiple approaches might succeed.

This skill should be used when breaking down frontend feature requirements into parallelizable work items (API clients, UI components, and integration tasks) with clear dependencies. Particularly useful for creating structured work breakdowns with Mermaid diagrams and organizing tasks for team development.
