Architectural refactoring guide for Rust applications covering type safety, ownership patterns, error handling strategies, API design, project organization, module structure, naming conventions, conversion traits, and idiomatic patterns. Use when refactoring Rust codebases, reviewing PRs for architectural issues, improving type safety, designing error handling strategies, or organizing project structure. Complements the rust-optimise skill (performance patterns). Does NOT cover performance optimization, memory allocation, or async concurrency tuning (see rust-optimise skill).
Use when upgrading to PHP 8.1+, implementing type safety, configuring PHPStan/Rector/PHP-CS-Fixer, or modernizing PHP code with enums, DTOs, and readonly properties.
Core TypeScript conventions for type safety, inference, and clean code. Use when writing TypeScript, reviewing TypeScript code, creating interfaces/types, or when the user asks about TypeScript patterns, conventions, or best practices.
Best practices and guidelines for TypeScript (2025-2026 Edition), focusing on TS 5.x+, modern type safety, and performance.
Use TypeScript for type-safe JavaScript: types, interfaces, generics, narrowing, tsconfig, modules, and strict mode. Use when writing or reviewing TypeScript, configuring tsconfig.json, defining types or interfaces, generics, type inference, or when the user mentions TypeScript, TS, or type checking.
Use when forced to use any. Use when any is too broad. Use when function types need any.
MUST be used whenever fixing correctness and error handling issues in a Flows app. This skill finds AND fixes bugs, missing error states, unhandled rejections, and edge-case failures — it does not just report them. Triggers: correctness, error handling, bug fix, edge case, crash, unhandled, null, undefined, empty state, loading state, error boundary, try catch, async error, useEffect cleanup, type guard, runtime error, robustness.
Use when writing, fixing, or editing TypeScript code that touches APIs, JSON, environment variables, storage, databases, browser APIs, SDKs, generated clients, or other external boundaries.
Implement branded (nominal/opaque) types in TypeScript to prevent accidental mixing of structurally identical types. Use when writing type-safe IDs (UserId, PostId), validated strings (Email, URL), unit-specific numbers (Meters, Seconds), or any scenario requiring nominal typing in TypeScript's structural type system.
TypeScript refactoring and modernization guidelines from a principal specialist perspective. This skill should be used when refactoring, reviewing, or modernizing TypeScript code to ensure type safety, compiler performance, and idiomatic patterns. Triggers on tasks involving TypeScript type architecture, narrowing, generics, error handling, or migration to modern TypeScript features.
Acts as a Senior Staff Engineer to enforce high-quality software development standards. Use this skill when the user asks for code implementation, architectural review, debugging, or technical design. It ensures all code is production-ready, typed, and architecturally sound.
Reviews Python code for type safety, async patterns, error handling, and common mistakes. Use when reviewing .py files, checking type hints, async/await usage, or exception handling.
