DO NOT USE THE APPLICATION NOTE SERVICE. Maintain and organize daily notes for the current project. Create, update, and manage these notes in a structured manner upon user request. Use this skill when the user requests "please make|create|write|add a note...".

Retrieve authoritative library documentation and code examples.

Use this skill when backend API contracts change and frontend types need synchronization. Triggers on: Pydantic model changes, REST endpoint updates, WebSocket message formats, or GraphQL schema modifications. Dynamically detects contract type from context. NOT for unrelated type definitions or internal backend-only changes.

Auditing and updating npm dependencies to prevent security vulnerabilities in TypeScript projects

Client-side state patterns for Web Components. Use when building interactive applications requiring state synchronization, reactive updates, or undo/redo functionality.

Select and apply numerical differentiation schemes for PDE/ODE discretization. Use when choosing finite difference/volume/spectral schemes, building stencils, handling boundaries, or estimating truncation error and dispersion.

Use when setting up code quality enforcement - configures linting, formatting, pre-commit hooks, CI workflows, and review checklists with advisory/soft/hard enforcement levels

Set up and configure MCP (Model Context Protocol) servers with Claude Code. Use when the user wants to connect Claude Code to external tools, databases, APIs, or services via MCP. Handles HTTP, SSE, and stdio server configurations with proper authentication.

Run .NET tests using dotnet CLI. Use when task involves executing unit tests, generating code coverage reports, or running benchmarks.

Integrate RubyCritic to analyze Ruby code quality and maintain high standards throughout development. Use when working on Ruby projects to check code smells, complexity, and duplication. Triggers include creating/editing Ruby files, refactoring code, reviewing code quality, or when user requests code analysis or quality checks.

Write modern C# code using .NET 8+, C# 12+ features, ASP.NET Core APIs, Entity Framework Core, and Blazor. Use for C# files (.cs), .NET projects, ASP.NET Core web apps, EF Core data access, minimal APIs, Blazor components, or LINQ queries.

Frontend development guidelines for Next.js + React 19 + shadcn/ui applications. Modern patterns including App Router, Server Components, Client Components, Server Actions, shadcn/ui with Tailwind CSS, React Hook Form, lazy loading, Suspense boundaries, Supabase client integration, performance optimization, and TypeScript best practices. Use when creating pages, components, forms, styling, data fetching, new features or working with Next.js/React code.

Comprehensive knowledge for creating, managing, and merging pull requests with Jira integration, following best practices for code review, deployment, and team collaboration

Fix lint errors and update typescript-coding skill with lessons learned. Use when fixing Biome lint errors, resolving linting issues, or when lint check fails. Automatically extracts patterns from fixes and adds prevention tips to typescript-coding skill.

Implement server-side validation with allowlists, specific error messages, type checking, and sanitization to prevent security vulnerabilities and ensure data integrity. Use this skill when creating or editing form request classes, when validating API inputs, when implementing validation rules in controllers or services, when writing client-side validation for user experience, when sanitizing user input to prevent injection attacks, when validating business rules, when implementing error message display, or when ensuring consistent validation across all application entry points.

Automatically generate and update tutorial documentation by analyzing recent code changes. Use this when code files are modified to keep documentation in sync.
