Frontend implementation and UI

Comprehensive project health auditor that compares original plans, requirements, and architecture against current implementation to identify gaps, deviations, and technical debt. Use when users ask to audit a project, review project status, compare plans vs reality, identify what's missing or incomplete, assess project health, find scope creep, detect architectural drift, or get back on track. Acts as a trusted advisor providing actionable recommendations based on industry best practices.

Comprehensive Zig 0.15.2 development expert. Use when writing Zig code, debugging memory issues, designing build systems, implementing comptime metaprogramming, handling errors, or cross-compiling. Automatically activated for any .zig file or build.zig work.

Use when: making a mistake, breaking build/tests, realizing wrong approach, misunderstanding requirements, using wrong patterns, forgetting conventions, receiving correction from user, unexpected behavior, or any error situation

Create and manage production Grafana dashboards for real-time visualization of system and application metrics. Use when building monitoring dashboards, visualizing metrics, or creating operational observability interfaces.

End-to-end software development workflow agent using memex-cli with multiple AI backends. Orchestrates 5 stages: (1) Requirements Analysis (Claude), (2) Functional Design (Claude), (3) UX Design (Gemini), (4) Development Planning (Codex), (5) Implementation & QA (Codex). Use for complete project development from idea to deployment.

Manages Vue state with Pinia including stores, getters, actions, and plugins. Use when building Vue applications needing centralized state, sharing state between components, or replacing Vuex.

Modern frontend frameworks including React, Vue, Angular, and Next.js. Master component-based architecture, state management, and full-stack development. Use when building interactive web applications or learning modern frontend technologies.

Teaches when to use Server Components vs Client Components in React 19, including the 'use client' directive and boundary patterns. Use when architecting components, choosing component types, or working with Server Components.

This skill should be used when orchestrating tmux sessions for multi-component development workflows. Use when creating complex multi-window, multi-pane tmux layouts via the Bash tool, especially for projects requiring simultaneous backend/frontend development, microservices, or parallel task execution. This skill provides patterns for session creation, pane management, and command orchestration using the user's custom tmux configuration.

Comprehensive purple team security assessment skill that analyzes codebases like a skilled penetration tester, identifies attack vectors, and provides remediation guidance. Use this skill when: (1) Performing security audits or code reviews, (2) Identifying vulnerabilities before deployment, (3) Running purple team exercises (offensive analysis + defensive remediation), (4) Checking for OWASP Top 10 vulnerabilities, (5) Scanning for hardcoded secrets, API keys, or credentials, (6) Analyzing authentication/authorization flaws, (7) Reviewing cryptographic implementations, (8) Auditing infrastructure-as-code (Terraform, K8s, Docker), (9) Generating security reports in Markdown, HTML, or JSON format. Triggers: "security audit", "purple team", "penetration test", "find vulnerabilities", "security review", "attack vectors", "remediate vulnerabilities", "OWASP", "security scan".

Guidance for configuring MCP servers in Claude Code projects. Covers transport selection, scopes, authentication, and security patterns. Use whenever adding MCP servers - projects, plugins, or any context.

Generate the full production Dockerfile for the backend with multi-stage build, proper dependencies, and Hugging Face Spaces compatibility.

React 18+ development with hooks, state management, component patterns, and Next.js integration. Use when building React applications or working with JSX/TSX components.

Audits code against CI/CD style rules, quality guidelines, and best practices, then rewrites code to meet standards without breaking functionality. Use this skill after functionality validation to ensure code is not just correct but also maintainable, readable, and production-ready. The skill applies linting rules, enforces naming conventions, improves code organization, and refactors for clarity while preserving all behavioral correctness verified by functionality audits.

Frontend development standards for Ellie's projects. Use when building frontend interfaces, components, pages, or applications. Enforces tech stack preferences (Leptos > HTMX/SolidJS > React, modern vanilla CSS, no Tailwind) and accessibility-first development. Always apply these standards unless they conflict with an existing project's established patterns.

Modern CSS features. Use for @function, style queries, range comparisons, if(), relative colors. (project)

Generate enterprise-grade web applications using Backstage Design System. Create admin dashboards, developer tools, and internal applications with modern React components, dark/light themes, and responsive design patterns based on Radix UI and Tailwind CSS.

Use when writing HTML/JSX with Tailwind CSS for common UI patterns like heroes, forms, lists, navbars, modals, cards, or any standard web component

Implement RxJS patterns for reactive programming in Angular. Use this skill when working with Observables, operators, subscriptions, async data flows, and error handling. Covers common patterns like combineLatest, switchMap, debounceTime, catchError, retry logic, and integration with Angular Signals using toSignal() and toObservable(). Ensures proper subscription cleanup with takeUntilDestroyed().
