Implement runtime validation and type safety using Zod schemas for Content Collections, API inputs, form data, and environment variables. Use this skill when validating user input, API requests, content schemas, or ensuring data integrity. When working on Content Collections schema definitions in src/content/config.ts, API route input validation with Zod, form validation (server-side and client-side), environment variable validation, component prop validation with runtime checks, URL and query parameter validation, request body and form data sanitization, TypeScript runtime type validation, or custom Zod refinements and transformations.

Automatically applies when building LLM applications. Ensures proper async patterns for LLM calls, streaming responses, token management, retry logic, and error handling.

Conducts comprehensive 90-minute discovery interviews to extract complete product requirements before implementation. Triggers when starting new SaaS projects, defining product scope, or validating ideas. Includes product management expertise to guide users through difficult questions.

Define and implement Service Level Indicators (SLIs) and Service Level Objectives (SLOs) with error budgets and alerting. Use when establishing reliability targets, implementing SRE practices, or measuring service performance.

Token-efficient retrieval using depth levels (L0-L5) and heading-based sections. Use for any file reads.

Write and maintain CSS following project conventions using consistent methodologies like Tailwind CSS, BEM, CSS modules, or utility classes, while creating distinctive, aesthetically excellent designs. Use this skill when writing CSS styles, applying Tailwind utility classes, creating custom CSS, working with styling files (*.css, *.scss, *.module.css, globals.css, tailwind.config.*), maintaining design systems and design tokens, defining CSS variables for colors and spacing, implementing typography styles with unique font choices, creating atmospheric backgrounds and depth, adding animations and micro-interactions, avoiding framework style overrides, avoiding generic "AI slop" aesthetics (purple gradients, Inter/Roboto everywhere, cookie-cutter designs), optimizing CSS for production with purging and tree-shaking, or ensuring consistent styling patterns across the application. Apply this skill when styling components, refactoring CSS code, setting up design systems, choosing fonts and colors, creating animat

Fix type assertions and improve TypeScript type safety. Use when encountering 'as unknown as' casts, manual type definitions that duplicate schema types, or unclear type errors in database queries, especially with Drizzle ORM relations. Also use when verifying types

This skill should be used when the user asks to "configure agent profile", "add skills to agent", "set up MCP servers", "configure agent tools", "write system prompt", "create agent workflow", "define agent commands", "add subagents", or needs to define what capabilities an agent has and how to orchestrate complex workflows in the runtime.

Finds code patterns using structural syntax matching with ast-grep. Use when searching for function definitions, class structures, API calls, or specific code patterns where grep would match false positives from comments or strings. For planning refactors, use planning-refactors instead.

Generates a complete iOS app icon set with all required sizes. Use when asked to create an app icon, design an iOS icon, generate app store artwork, or make an icon for an iPhone/iPad app. Follows a philosophy-first approach - first defining the visual identity and concept, then producing production-ready icons.
