Coding standards, frameworks, refactoring, and code review (16.8K skills)
Troubleshoot WxJava failures using logs, exceptions, and request details. The skill helps isolate configuration, access token, signature, payment certificate, callback, and network issues, then proposes a minimal fix with steps to verify the result.
Plan a WxJava integration for Java, Spring Boot, or Solon projects. Get module choices, dependency and configuration examples, minimal API calls, and local verification steps tailored to the WeChat product and account setup.
Review web interface code against the latest Web Interface Guidelines to identify issues in design, usability, and accessibility. Specify files or a file pattern, and receive concise findings with file names and line numbers.
Refactor React components into reusable pieces with clearer interfaces. Provides patterns for replacing excessive boolean settings, sharing state through providers, and designing component libraries, with additional guidance for React 19 APIs.
Add animations to React interfaces using the browser's built-in view transitions. Guides page changes, shared elements that move between views, list reordering, component appearance, and loading reveals, with CSS styling and Next.js integration guidance.
Write, review, and refactor React and Next.js code using performance guidelines ranked by impact. Covers sequential data requests, downloaded code size, server work, and unnecessary rendering to guide concrete implementation improvements.
Build and improve mobile apps with React Native and Expo using prioritized implementation rules. Covers faster lists, animations, images, navigation, state management, and native dependencies, with explanations and code examples for reviewing common implementation choices.
This skill is identified as development related, but the supplied text gives no concrete workflow or expected result. Its name suggests continuous learning, yet the material does not explain any learning behavior or how to use it.
Plan and implement database structure changes and data transfers using Sequelize, TypeORM, or Prisma. Covers staged changes to keep services running, rollback procedures to undo changes, backups, and migration verification.
Design a database layer from business requirements, access patterns, and expected growth. Compare database technologies, define tables and relationships, and plan indexes, caching, scaling, migrations, backups, and recovery with clear reasons and trade-offs.
Guides background processing in Node.js and TypeScript with BullMQ and Redis. Covers job queues, which hold tasks for later execution, along with scheduling, priorities, rate limits, worker concurrency, and dependencies between processing steps.
Build site search with Algolia using React InstantSearch patterns for search input, filters, and pagination. The skill also covers Next.js server rendering and strategies for keeping searchable records synchronized as source data changes.
Make system design decisions by clarifying requirements, identifying constraints, and comparing the benefits and drawbacks of different approaches. Record the reasoning in architecture decision records, or ADRs, while considering simpler alternatives and the team's experience.
Plan backend systems with clear module boundaries and dependency rules. This skill helps select architecture patterns, organize business logic, and outline migration steps for systems that are easier to maintain and test.
Write and improve C code for systems and embedded projects, with explicit memory ownership, pointer handling, and error checks. The skill also covers build files, unit tests, debugging, and performance measurement.
Write complex SQL, improve slow queries, and design database schemas for transaction processing and analytics. Uses schema details and query execution plans to guide indexing, validate results, and assess performance with realistic data volumes.
Design REST and GraphQL APIs by clarifying who will use them and how. Define data structures, errors, authentication, pagination, and versioning, then review examples to make the interface consistent and easier to use.
Turn a project idea into a detailed system plan before coding. Organize architecture, data flows, dependencies, and file-level tasks in a linked Markdown workspace, with research references, consistency checks, and saved state for resuming later.
Audit and improve web accessibility using WCAG 2.1 guidelines. Covers image descriptions, color contrast, keyboard controls, forms, and screen reader support, with code examples and automated and manual checks to guide fixes.
Reorganize long AGENTS.md, CLAUDE.md, and similar instruction files into a short main file with links to topic-specific documents. Identifies conflicting rules and deletion candidates, then checks links and coverage so instructions remain organized and accessible.
Document major technical decisions with their context, alternatives, reasoning, and consequences. The skill provides Architecture Decision Record templates and maintenance practices so teams can review past choices, track replacements, and explain decisions to new members.
Choose how an API, the interface software uses to exchange data, should work. Covers REST, GraphQL, and tRPC selection, consistent responses, pagination, versioning, authentication, request limits, documentation, and security review considerations.
Structure Avalonia interfaces with Zafiro.Avalonia using shared styles, reusable components, and purpose-built layout containers. Guides reductions in duplicated XAML, the interface markup, and deeply nested layouts, while covering themes, icons, and interaction behavior.
Integrate USDC payments into AI agents on Base L2. Guides setup for earning or paying, generates tailored code, and verifies configuration, covering escrow that holds funds until delivery and instant payments for HTTP requests.
