Guides modern Rails 8 code architecture decisions and patterns. Use when deciding where to put code, choosing between patterns (service objects vs concerns vs query objects), designing feature architecture, refactoring for better organization, or when user mentions architecture, code organization, design patterns, or layered design.
OpenSpec Spec-Driven Development Assistant - An AI-aided programming framework based on the OPSX workflow. Align requirements with AI before writing code, and manage changes using a Schema-driven artifact dependency system. Trigger Conditions: 1. User mentions "openspec", "opsx", or spec-driven development 2. User wants to start new feature development or refactoring 3. User needs to explore complex problems or clarify requirements 4. User complains about AI misunderstanding or frequent rework 5. User uses slash commands such as /opsx:new, /opsx:ff, /opsx:apply, etc. 6. During project initialization or preparation for major changes
Apply meta-principles of software craftsmanship: DRY, orthogonality, tracer bullets, and design by contract. Use when the user mentions "best practices", "pragmatic approach", "broken windows", "tracer bullet", or "software craftsmanship". Covers estimation, domain languages, and reversibility. For code-level quality, see clean-code. For refactoring techniques, see refactoring-patterns.
Senior Node.js developer. Use when building, reviewing, or refactoring Node.js applications. Enforces modern Node.js 22+ patterns, native APIs, performance, and production-ready practices.
Apply production-ready best practices for weapp-vite projects. Use when creating or refactoring mini-program projects with weapp-vite, designing directory/config conventions, choosing subpackage and chunk strategy, enabling auto routes/components, setting CI/devtool workflows, or debugging build/output issues in `vite.config.ts` and `app.json`.
Comprehensive naming convention guide for TypeScript and Angular applications. Covers casing rules (camelCase, PascalCase, UPPER_CASE), prefix conventions (I for interfaces, _ for private, T for generics), boolean naming, the S-I-D principle (Short, Intuitive, Descriptive), context duplication, and structured naming patterns (P/HC/LC for variables, A/HC/LC for functions). Use when writing, reviewing, or refactoring TypeScript code. Triggers on tasks involving naming, variables, functions, interfaces, or code style.
Vue SFC implementation playbook for weapp-vite mini-program projects, including `<script setup lang="ts">`, JSON macros (`defineAppJson/definePageJson/defineComponentJson`), `usingComponents`, template directive compatibility, and SFC compile/runtime troubleshooting. Use when users ask about `.vue` authoring or refactoring in mini-programs (e.g. "v-model 在小程序里怎么写", "definePageJson 和 <json> 怎么选", "SFC 编译报错", "usingComponents 不生效").
Write, review, or improve UIKit code following best practices for view controller lifecycle, Auto Layout, collection views, navigation, animation, memory management, and modern iOS 18–26 APIs. Use when building new UIKit features, refactoring existing views or view controllers, reviewing code quality, adopting modern UIKit patterns (diffable data sources, compositional layout, cell configuration), or bridging UIKit with SwiftUI. Does not cover SwiftUI-only code.
Delegate coding tasks to Google Jules AI agent for asynchronous execution. Use when user says: 'have Jules fix', 'delegate to Jules', 'send to Jules', 'ask Jules to', 'check Jules sessions', 'pull Jules results', 'jules add tests', 'jules add docs', 'jules review pr'. Handles: bug fixes, documentation, features, tests, refactoring, code reviews. Works with GitHub repos, creates PRs.
Go-specific code review with 6-phase methodology: Context, Automated Checks, Quality Analysis, Specific Analysis, Line-by-Line, Documentation. Use when reviewing Go code, PRs, or auditing Go codebases for quality and best practices. Use for "review Go", "Go PR", "check Go code", "Go quality", "review .go". Do NOT use for writing new Go code, debugging Go bugs, or refactoring -- use golang-general-engineer, systematic-debugging, or systematic-refactoring for those tasks.
Comprehensive Rust coding guidelines covering ownership, error handling, async patterns, traits, testing, performance, clippy, and documentation. Use when writing new Rust code, reviewing or refactoring existing Rust, implementing async systems with Tokio, designing error hierarchies, choosing between borrowing and cloning, setting up tests or benchmarks, configuring linting, or optimizing performance. Do not use for non-Rust languages or general software architecture unrelated to Rust idioms.
Write and refactor TypeScript code in repos that use Effect-TS services, Zod schemas, event-sourced persistence, and namespace-driven architecture. Use this skill when implementing features, fixing bugs, writing tests, or refactoring in opencode or any TypeScript codebase built on the same stack (Effect DI, Drizzle ORM, Hono routes, Bun runtime). Triggers on tasks involving Effect services, namespace modules, Zod schema definitions, SyncEvent patterns, tool implementations, test writing, or code review in Effect-based TypeScript projects.
