Frontend

Apply a Content Driven Development process to AEM Edge Delivery Services development. Use for all development tasks, including building new blocks, modifying existing blocks, making changes to core decoration functionality, etc.

The Block Collection and Block Party are repositories for existing AEM blocks, build tools, code snippets, integration patterns, plugins, and more. Use this skill anytime you are developing something and want to find a reference to use as a starting point.

PREPARE PHASE: Research methodologies and documentation gathering workflows.Provides systematic research approaches, source evaluation criteria, documentationtemplates, API exploration techniques, and technology comparison frameworks.Use when: conducting technology research, evaluating documentation sources,comparing framework options, analyzing API documentation, gathering requirements.

Deployment architecture, multi-tenancy design, and environment-specific deployment commands. Use when the user asks about how the application is deployed, multi-tenant architecture with Navigator, Fly.io deployment, or frontend stack details.

CROSS-CUTTING: Security patterns and best practices for ALL PACT phases.Provides OWASP Top 10 guidance, authentication/authorization patterns, input validation,secure coding practices, secrets management, and security testing checklists.Use when: implementing authentication, handling user input, storing secrets,designing authorization, reviewing code for vulnerabilities, planning security tests.

Use this skill to inspect what a Rails page currently displays, extract HTML content, or verify rendering WITHOUT starting a dev server. Useful for understanding page output before making changes, debugging views, searching for content, or testing that pages work correctly. Provides scripts/render.rb for quick page inspection and HTML extraction.

ARCHITECT PHASE: Architectural design patterns, component templates, and system design guidance.Provides proven architectural patterns including microservices, layered architecture,event-driven systems, C4 diagram templates, API contract formats, and design anti-patterns.Use when: designing system architecture, creating component diagrams, defining interfaces,planning component boundaries, choosing architectural patterns, organizing system modules,or when user mentions: architecture, components, system design, diagrams, C4, microservices,API contracts, service boundaries, architectural patterns.Use for: component design, interface definition, system boundaries, dependency management,architecture documentation, design patterns, integration patterns.DO NOT use for: code implementation details, specific framework syntax, database schema design,frontend-specific patterns, testing strategies, or security implementation (use dedicated skills).

CODE PHASE (Frontend): Client-side implementation patterns and best practices.Provides component architecture patterns, state management strategies, accessibilityguidelines, performance optimization, and responsive design approaches.Use when: building UI components, managing state, implementing forms, optimizingperformance, ensuring accessibility, creating responsive layouts.

Working with the Navigator Go submodule for web server fixes and enhancements. Use when deployment plans require Navigator changes, config parsing issues arise, or new routing/proxy behavior is needed.

TEST PHASE: Testing strategies, patterns, and quality assurance workflows.Provides test strategy frameworks, coverage guidelines, unit/integration/e2e patterns,performance testing approaches, and security testing checklists.Use when: designing test strategies, writing tests, evaluating coverage,planning QA workflows, implementing test automation.

CODE PHASE (Database): Data layer implementation patterns and best practices.Provides schema design patterns, query optimization strategies, indexing guidelines,data integrity constraints, migration patterns, and database security practices.Use when: designing schemas, writing queries, optimizing performance, planningmigrations, implementing data validation, ensuring data integrity.

Diagnose xcodebuild builds using argus. Use this instead of parsing xcodebuild output to avoid filling the context window. Query build errors, warnings, slowest targets, bottlenecks, implicit/redundant dependencies, and dependency graph with linking information for optimization analysis.

Automatically discover frontend development skills when working with React, Next.js, UI components, state management, data fetching, forms, accessibility, performance optimization, or SEO. Activates for frontend web development tasks.

Standardize typed forms in this repo. Use whenever a feature needs a form or an existing form is being refactored. Prefer SchemaForm + formFields + zod for typed inputs and consistent UI/validation; use react-hook-form Controller only for custom fields that SchemaForm cannot render.

Create world-class, accessible, responsive interfaces with sophisticated interactive elements including chat, terminals, code display, and streaming content. Use when building user interfaces that need professional polish and developer-focused features.

Best practices for Tuist projects. Use when working with Tuist manifests, generating projects, or building with xcodebuild in Tuist projects.

Fill DOCX template forms programmatically while preserving 100% of original structure - logos, footers, styles, metadata. Zero-artifact insertion for forms, applications, and standardized documents. Output indistinguishable from manual filling.

Extract and decompress must-gather archives from Prow CI job artifacts, generating an interactive HTML file browser with filters

Interactive markdown review with web UI. Use when: - User says "review this", "check this plan", "/review" - User wants to give feedback on a plan or document - User says "let me review", "피드백", "검토해줘" - User specifies a file path to review (e.g., "review /path/to/file.md")

Analyze Kubernetes resource lifecycle in Prow CI job artifacts by parsing audit logs and pod logs from GCS, generating interactive HTML reports with timelines
