Coding standards, frameworks, refactoring, and code review (16.6K skills)
Implement or review login and access controls for applications and APIs. Helps define token lifetimes, session handling, and permissions for specific resources, with checks for user identity, organization boundaries, credential storage, and authentication failures.
Keep development work aligned with the original request by recording requirements, protected behavior, and validation checks. Use phase reviews, deviation notices, and a final audit for tasks involving APIs, stored data, or changes that must preserve existing behavior.
Guide cross-platform app development with Avalonia UI and Zafiro using consistent architecture and coding conventions. Keep screen logic separate from UI dependencies, handle errors explicitly, and reuse existing helpers with ReactiveUI and DynamicData.
Build Python applications that keep other tasks moving while waiting for network, database, or file operations. Guides the choice of asyncio patterns, with timeouts, cancellation, error handling, and testing for asynchronous code.
Create output schemas, definitions of result fields and display settings, for an Apify Actor by inspecting its source code. Generate dataset and output files, add key-value storage definitions when needed, and update actor.json to reference them.
Coordinate specialist agents to investigate and improve application performance across databases, backend services, frontend code, and delivery infrastructure. Establish baseline measurements, address observed bottlenecks, validate changes with load tests, and set up monitoring to detect future slowdowns.
Review the journey from discovering an API to receiving the first successful response. Identify delays in signup, authentication, setup, and documentation, then plan improvements using test environments, interactive examples, clearer errors, and measurements of progress.
Review system architecture and major design changes for scalability, resilience, and maintainability. Identify risks, compare design tradeoffs, and document recommendations and next steps across services, APIs, data storage, security, and deployment.
Turn a plain language app request into a project plan, technology choices, and coordinated development tasks. Use project templates to structure web, mobile, desktop, API, or command line applications, with agents handling different development responsibilities.
Ask GitHub Copilot for code explanations, reviews, or short code examples through its command line interface. The skill supports requests without an interactive screen and named sessions for follow-up questions.
Implement controlled retries and request throttling for external APIs. Covers retryable errors, provider-specified waiting times, increasing delays with random variation, retry limits, and checks that repeating a request will not cause unintended duplicate changes.
Develop firmware and drivers for ARM Cortex-M microcontrollers, including Teensy, STM32, nRF52, and SAMD. Get complete modules with initialization and usage examples, plus guidance on interrupts, memory handling, data transfers, performance, and fault diagnosis.
Review a repository’s architecture using Ontoly Software Graph, a map of code relationships. Explain module boundaries, package structure, dependencies, and architectural risks, with graph evidence and a stated confidence level.
Design and build Apify integrations for workflow platforms, AI agents, AI frameworks, or applications. Follow guidance for authentication, asynchronous cloud task execution, result retrieval, spending limits, error handling, testing, and release preparation.
Choose between REST, GraphQL, and tRPC based on who uses an API and how it is deployed. Define consistent responses, pagination, authentication, and versioning, supported by concrete request examples and failure cases.
Design connections between APIs and services, including webhooks, which notify other systems when events occur. Define event formats, retries, duplicate prevention, and recovery steps for workflows such as order processing and data pipelines.
Generate client libraries for REST APIs, with authentication, retries, typed request and response models, error classes, and pagination helpers. Language-specific patterns and usage examples show how applications can call API resources.
Make system architecture decisions by clarifying requirements and constraints, comparing benefits and drawbacks, and considering simpler alternatives. Record the reasoning in ADRs, architecture decision records, so significant choices and their rationale are documented.
Plan backend architecture using Clean Architecture, Hexagonal Architecture, or Domain-Driven Design. Clarify business boundaries, choose a suitable structure, define how modules depend on each other, and outline migration steps and validation checks.
Document major technical choices as Architecture Decision Records, or ADRs. Capture the context, alternatives, reasons, and consequences, then organize related records and track whether decisions are proposed, accepted, retired, or replaced.
Build and debug Apify Actors, cloud programs for web scraping, automation, and data processing. Get guidance on language templates, input and output schemas, runtime code, local testing, and deployment, with practices for handling credentials and external data.
Design, build, debug, and optimize connections to external APIs. The skill covers REST, GraphQL, event notifications through webhooks, authentication, retries, request limits, and logging to help produce integrations whose failures can be traced.
Design REST or GraphQL APIs by defining who will use them, what data they expose, and how requests behave. Establish error formats, versioning, pagination, and authentication, then review examples for consistency before implementation.
Build web animations with Anime.js, from staggered text and image reveals to SVG shape changes and animated lines. Coordinate timing, overlapping motion, and responses to user input while accounting for accessibility and performance.
