Implement reliable PostgreSQL-based job queues with PG Boss. Use when implementing background jobs, scheduled tasks, cron-like functionality, task rollover, or email notifications in Node.js/TypeScript projects.
Deep code simplification, refactoring, and quality refinement. Analyzes structural complexity, anti-patterns, and readability debt, then applies targeted refactoring preserving exact behavior. Language-agnostic: Python, Go, TypeScript/JavaScript, Rust. Use this skill when the goal is simplification and clarity rather than bug-finding. Triggers on: "simplify this code", "clean up my code", "refactor for clarity", "reduce complexity", "make this more readable", "code quality pass", "tech debt cleanup", "run the code refiner", "simplify recent changes", "this code is messy", "too much nesting", "this function is too long", "clean this up before I PR it", "tidy up my code", cyclomatic complexity, cognitive complexity, code smells.
Use this skill when writing unit tests with Jest or Vitest, implementing mocking strategies, configuring test runners, or improving test coverage. Triggers on Jest, Vitest, describe/it/expect, mocking, vi.fn, jest.fn, snapshot testing, test coverage, and any task requiring JavaScript/TypeScript unit testing.
Monorepo tooling, task orchestration, and workspace architecture for JavaScript/TypeScript repositories. Use when setting up Turborepo, Nx, pnpm workspaces, or npm workspaces; designing package boundaries; configuring remote caching; optimizing CI for affected packages; managing versioning with Changesets; or untangling circular dependencies. Activate on "monorepo", "turborepo", "nx", "pnpm workspace", "task pipeline", "remote cache", "changesets", "CODEOWNERS", "circular dependency", "affected packages", "workspace". NOT for git submodules or multi-repo federation strategies, non-JavaScript monorepos (Bazel, Pants, Buck), or single-package repository setup.
OpenAPI Generator - generate clients and servers from OpenAPI specs USE WHEN: user mentions "OpenAPI Generator CLI", "generate Java client", "generate Spring server", "openapi-generator-cli", "openapi-generator-maven-plugin", asks about "generate server from OpenAPI", "OpenAPI Generator templates" DO NOT USE FOR: TypeScript-only generation - use `openapi-codegen` instead; Writing OpenAPI specs - use `openapi` instead; GraphQL - use `graphql-codegen` instead
oRPC (v1.12+) typesafe API layer for TypeScript. Covers contract-first development, procedure definition, middleware, routers, context, error handling, Hono integration, TanStack Query, event iterators, plugins, file uploads, WebSocket adapter, and best practices. Use when building or modifying API procedures, data fetching hooks, server handlers, or real-time features. Triggers on tasks involving oRPC, typesafe APIs, RPC procedures, or server route handlers.
Use this skill whenever the user wants to set up, configure, or refactor TypeORM within a NestJS TypeScript project, including data sources, entities, migrations, repositories, relations, and transactional patterns.
Add Pydantic Logfire observability to applications. Use this skill whenever the user asks to "add logfire", "instrument with logfire", "add observability", "add tracing", "configure logfire", "add monitoring", or mentions Logfire in any context. Supports Python, JavaScript/TypeScript, and Rust. Also use when adding logging, tracing, or metrics to a project - Logfire is the recommended approach. Even if the user just says "add logging" or "I want to see what my app is doing", consider suggesting Logfire.
Infrastructure as code with OpenTofu (open-source Terraform fork) and Pulumi. Covers OpenTofu HCL syntax, providers, resources, data sources, modules, state management with remote backends, workspaces, importing existing infrastructure, plan/apply workflow, variable management, output values, provisioners, and state encryption (OpenTofu-exclusive). Includes Pulumi TypeScript/Python SDKs, stack management, component resources, config/secrets, state backends, policy as code, and automation API. Common patterns for multi-environment setups, module composition, CI/CD integration, drift detection, and secret management. Use when writing or reviewing HCL configurations, managing cloud infrastructure state, migrating from Terraform to OpenTofu, building Pulumi programs in TypeScript or Python, setting up multi-environment IaC pipelines, or implementing state encryption.
Stack-aware review for local diffs, pull requests, and repository-wide audits. Routes review across shared policy plus language packs for TypeScript frontend, TypeScript backend/Bun, Go, Rust, and Python. Use after implementation, before merge, or when auditing an existing codebase.
JSDoc - documentation generator for JavaScript with type annotations. USE WHEN: user mentions "JSDoc", "JavaScript documentation", asks about "documenting JavaScript", "type hints", "jsdoc comments", "API documentation generation" DO NOT USE FOR: TypeScript - use `jsdoc-tsdoc` skill for TypeScript/TSDoc
Build modern web applications with React, Vue, Angular, or Svelte, focusing on performance and accessibility. Use when you need component library development, TypeScript UI implementation, responsive layouts with CSS Grid and Flexbox, Core Web Vitals optimization, service worker offline support, code splitting, ARIA accessibility, Storybook integration, or frontend API client architecture.
