Coding standards, frameworks, refactoring, and code review (16.6K skills)
Plan how an Angular app stores and updates data used by its screens. Covers local and shared state, choices involving Signals, NgRx, and RxJS, synchronization with server data, debugging, and migration from older patterns.
Guide AI coding work toward simple implementations, focused edits, and explicit assumptions. Use it when writing, reviewing, or refactoring code to keep changes tied to the request and define success through tests or other concrete checks.
Create Android projects, deploy apps to devices, and manage SDK packages and emulators through the `android` command-line tool. It also supports screenshots, interface structure inspection, environment checks, and Android documentation searches.
Analyze Antigravity coding session artifacts to explain scope changes, repeated rework, and underlying causes. Produce an evidence-based report with confidence levels, prompt assessments, recurring problem areas, and prioritized recommendations for improving future development sessions.
Design APIs and interfaces between parts of an application with clear input and output types, consistent errors, and predictable names. The guidance helps you extend existing interfaces while preserving compatibility for the code that uses them.
Plan and carry out a migration from AngularJS to Angular. It covers gradual migration with both frameworks running together, component and service conversion, routing and form changes, plus testing and preparation for the final switch.
Build Angular interfaces that handle loading, errors, and data display. This skill guides component work involving asynchronous data, which arrives after a request, and helps organize the interface states needed to present it.
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.
Plan and develop Android apps with guidance on technology choices, app structure, screen design, testing, debugging, performance, and releases. Covers native Kotlin and Java development alongside Flutter, RN, KMM, and hybrid approaches.
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.
Coordinate multiple skills to deliver a SaaS prototype, audit web security, build an AI agent, test browser behavior, or design a domain model. Verify each step before continuing and report completed work with supporting evidence.
Build search features with Algolia using guidance on search indexes, data organized for searching, React InstantSearch, and relevance tuning. Use it when implementing autocomplete, filtering by attributes, or results that update as users type.
Build REST API endpoints, the routes applications use to exchange data, with input validation, authentication, access checks, error handling, and documentation. Covers creating, reading, updating, and deleting records, plus pagination and consistent response formats.
Develop Angular v20+ applications using Signals for reactive state and Standalone Components. Supports gradual migration from NgModules, Zoneless configuration, server-side rendering, hydration, and performance optimization with development testing before production use.
Turn a system description into REST API endpoints, the URLs and operations applications use to exchange data. Choose an endpoint list or detailed specifications covering authentication, request fields, responses, error codes, and pagination for lists.
Build voice skills for Amazon Alexa and plan an assistant that uses Claude for its intelligence. Covers integration with AWS services including Lambda, DynamoDB, Polly, Transcribe, and Lex, as well as Smart Home.
Build Android screens with Jetpack Compose using guidance on UI state, navigation, Material Design 3, and rendering performance. Includes patterns for separating screen logic from reusable components and migrating existing XML layouts.
Design or review command-line tools that AI agents can call. Use 98 proposed rules to define structured output, input validation, error handling, safety controls, and help information, with three levels for gradual adoption.
Document the tools an AI agent may call, including input rules, caller permissions, execution limits, and retry conditions. Produce a tool register and verification plan for reviewing registrations or MCP routing designs.
Coordinate multiple Claude Code workers through an existing Kanban board. This guide describes task dispatch, automated checks before AI review, per-task cost tracking, human intervention, and recovery after restarts; the runtime and integrations require separate installation.
Guide a scoped coding task through specification, implementation, and review. Set acceptance criteria, verification checks, iteration limits, and approval gates, then correct identified gaps until the requirements pass or a stopping condition is reached.
Coordinate software development tasks across specialized agents for requirements, planning, architecture, implementation, review, testing, and deployment. Keep versioned reports, concise progress summaries, and open decisions organized, with user confirmation before moving between stages.
Create, update, or audit AGENTS.md instructions using evidence from repository files and CI workflows. Preserve maintainer policies while clarifying commands, validation steps, and directory-specific rules that guide coding agents.
Inspect local AI coding session logs with agenttrace to identify cost spikes, delays, failed tools, and retry loops. Produce readable reports, compare attempts, and configure automated checks for unusual or unhealthy runs.
