Provides comprehensive TypeScript development expertise and coding standards. Ensures type safety through strict type checking, implements clean code patterns, and maintains consistent architectural decisions. Specializes in advanced type system features including generics, conditional types, mapped types, and template literal types.Use when: working with TypeScript files (.ts/.tsx), defining type definitions and interfaces, implementing generic programming patterns, designing type-safe APIs, handling complex type transformations, integrating TypeScript with React/Vue/Angular frameworks, configuring strict mode settings, resolving type errors, or optimizing type performance in large codebases.

Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Composable atomic blocks for categorical meta-prompting. Defines 16 reusable blocks across 4 layers (Assessment, Transformation, Refinement, Composition) that can be composed to build custom workflows. Enables progressive disclosure: simple commands work unchanged, power users can override individual blocks or compose freely.

This skill should be used when implementing features with parallel exploration or competition. Triggers on "build", "create", "implement", "try both approaches", "compare implementations". Routes to omakase-off (entry gate for design exploration) or cookoff (exit gate for parallel implementation).

Meta-skill for improving and optimizing prompts using Anthropic's prompt engineering best practices. Provides the 4-step improvement workflow (example identification, initial draft, chain of thought refinement, example enhancement), keyword registries for documentation lookup, and decision trees for improvement strategies. Use when improving prompts, optimizing for accuracy, adding chain of thought reasoning, structuring with XML tags, enhancing examples, or iterating on prompt quality. Delegates to docs-management skill for official prompt engineering documentation.

Create new slash commands for DevAgent workflows. Use when you need to create a new command file in .agents/commands/ and symlink it to .cursor/commands/ for Cursor IDE integration. This skill handles the complete command creation workflow including file generation, symlink creation, and structure validation.
