Advanced code search tool that finds definitions, usages, tests, and references across the entire codebase. Use when you need to understand how a symbol is used throughout the project.

"How do I deliver maximum value with minimum cost?" - The capability of finding optimal paths to insight. Not restriction, but excellence at efficiency. Use when (1) spawning as opus-distillatus agent for focused synthesis, (2) token budget matters and quality cannot suffer, (3) working on tasks where the process itself is valuable and will be examined, (4) combining multiple sources into crystallized insight. This is an IDENTITY skill - it describes what you're excellent at, not what you can't do. Trust your judgment to find where tokens create value.

Crea planes de implementación realistas para MVPs de 2-4 semanas. Define alcance mínimo, stack tecnológico, tareas priorizadas y cronograma. Úsalo después de validar una idea para planificar la construcción del producto mínimo viable.

Quick reference for uv (fast Python package manager) operations to save tokens. Use when creating virtual environments, installing packages, managing dependencies, or when user asks about uv commands. Provides concise patterns for Python project setup and package management.

Token-efficient codebase navigation through intelligent symbol loading and querying. Use this skill when implementing new features (find existing patterns), exploring codebase structure, searching for components/functions/types, or understanding architectural layers. Reduces token usage by 60-95% compared to loading full files. Layer split enables 50-80% additional backend efficiency.

Creates Application Slash Command definition and handler following clean architecture

Patterns for error handling using Result<T,E> and Validation<T,E> monads. Never use try/catch/throw. Covers error type design, error constructors, and error composition. Use when handling errors or defining error types. Includes script for generating error types.

Automate web browser interactions using natural language via CLI commands. Use when the user asks to browse websites, navigate web pages, extract data from websites, take screenshots, fill forms, click buttons, interact with web applications, monitor network requests, debug web pages, or extract design tokens. Triggers include "browse", "navigate to", "go to website", "open webpage", "extract data from webpage", "screenshot", "web scraping", "fill out form", "click on", "search for on the web", "check network requests", "debug page", "get design tokens", "extract colors", "analyze website design". When taking actions be as specific as possible.

Comprehensive context and token usage management for Claude Code. Use this skill when working with large codebases, managing context window budget, optimizing file loading strategies, or when responses indicate context limitations. Helps with token analysis, file organization, query optimization, and context-efficient development workflows.

Expert in building MCP servers using the Official Python MCP SDK. Use this when defining tools, resources, and prompts that allow AI agents to manage application state.

Skriptoteket frontend development (FastAPI backend + full Vue/Vite SPA) using the HuleEdu-aligned stack (Vue 3.5.x + Vite + TypeScript, Pinia, Vue Router, Tailwind CSS v4 tokens/@theme, HuleEdu design tokens, pnpm). Use for working in the `frontend/` pnpm workspace, SPA hosting/history fallback, implementing SPA features (auth, routing, state, API clients), and keeping the UI/auth model compatible with future HuleEdu teacher login integration (same entry point, no separate login).

Deep dive into prompt-tsx patterns used in vscode-copilot-chat, including component lifecycle, async rendering, priority system, and token budget management

Theming StickerNest with CSS tokens and design variables. Use when the user asks about themes, CSS variables, dark mode, skinning, color schemes, theme tokens, widget theming, or customizing appearance. Covers theme system, token inheritance, and widget styling.

Validates output-style persona definitions, behavior specifications, and keep-coding-instructions decisions. Use when reviewing, auditing, or improving output-styles, checking persona clarity, validating behavior concreteness, assessing coding-instructions appropriateness, or verifying scope alignment (user vs project). Also triggers when user asks about output-style best practices, wants to improve style effectiveness, or needs help with persona definition.

Apply functional and compositional architecture patterns when designing systems, modules, and components. Use when creating architecture definitions, designing system boundaries, defining interfaces, or building modular systems.

Use this skill whenever the user wants to design, implement, or refactor authentication and authorization in a NestJS TypeScript backend, including JWT, sessions, refresh tokens, guards, roles/permissions, and integration with modules/services/controllers.

WCAG 2.2 accessibility patterns for web components. Use when implementing focus management, keyboard navigation, screen reader support, reduced motion, high contrast mode, or touch targets. Integrates with project's accessibility.css tokens. (project)

Generates interactive p5.js algorithmic art artifacts. Requires defining an Algorithmic Philosophy before coding. Enforces seeded randomness.

Track token usage and costs across agents for budget management

Package entire code repositories into single AI-friendly files using Repomix. Capabilities include pack codebases with customizable include/exclude patterns, generate multiple output formats (XML, Markdown, plain text), preserve file structure and context, optimize for AI consumption with token counting, filter by file types and directories, add custom headers and summaries. Use when packaging codebases for AI analysis, creating repository snapshots for LLM context, analyzing third-party libraries, preparing for security audits, generating documentation context, or evaluating unfamiliar codebases.
