Skill UI

Automates devcontainer creation with Claude Code plus language-specific tooling for Python, Node/TypeScript, Rust, and Go, layering templates, extensions, and post-create commands so teams can spin up isolated, persistent workspaces quickly.

This guide provides a comprehensive, production-grade architecture for implementing analytics using PostHog. It covers best practices for event taxonomy design, SDK layering (client and server), feature flag management, and integrating the data pipeline (CDP). Ideal for tracking user lifecycle, feature adoption, and revenue in complex web applications.

Guides Java engineers through Spring Boot backend architecture, REST API design, service layering, repository patterns, caching, async handlers, logging, middleware, and resilience practices for scalable production services.

Creates a comprehensive onboarding guide for new teammates by extracting project context from the knowledge graph, layering architecture descriptions, guiding tours, and highlighting complex files so newcomers can ramp up quickly.

A comprehensive guide for building robust, professional Go Command Line Interfaces (CLIs). Learn the industry-standard approach using Cobra for command structure and Viper for advanced configuration layering (flags, env vars, config files). Covers command organization, flag validation, argument handling, and best practices for Unix-like tools.

A collection of production-ready patterns for integrating frontend applications with backend APIs. It solves complex asynchronous issues such as race conditions, stale data, and duplicate requests. Patterns include centralized API layering, request cancellation (AbortController), exponential backoff retries, debouncing, and request deduplication, ensuring highly resilient and reliable user experiences.

This guide provides a comprehensive blueprint for implementing enterprise-grade Role-Based Access Control (RBAC) for Notion integrations. It covers the full OAuth 2.0 flow for public, multi-tenant apps, secure per-workspace token storage (with encryption), and layering custom permission models (admin/editor/viewer) over Notion's native permissions. Essential for building robust, secure, and audit-compliant Notion applications.

Provides comprehensive architectural guidelines for building scalable Webiny admin extensions. This pattern addresses separating business logic (headless features: UseCase/Repository/Gateway) from presentation logic (Presenters/Hooks/Components). It covers the standardized directory structure and layering necessary for creating robust, maintainable, and highly modular administrative interfaces.

This guide details setting up advanced Command and Control (C2) redirectors, acting as protective intermediaries between implant beacons and the hidden team server. It covers using Nginx and Apache for request filtering based on Malleable C2 profiles, layering Let's Encrypt TLS, and implementing advanced OPSEC controls like domain fronting, geo/UA filtering, and decoy diversion. Essential for red-teaming operations requiring high resilience against blue-team detection and takedown.

This comprehensive tool performs an architectural audit of a codebase, mapping module dependencies, checking layering integrity, and flagging structural decay. Drawing on classic engineering principles (like Conway's Law and Testability Seams), it provides a deep assessment of the project's health and structure. Ideal for large-scale code reviews or onboarding new developers.

This guide outlines best practices for structuring supplementary materials for OOPSLA submissions. It emphasizes the 'layering decision,' ensuring the core body can stand alone while appendices provide necessary proofs and technical details. It covers maintaining double-anonymity across all included content and performing crucial cross-checks for consistency across multiple review rounds.

This skill performs a comprehensive architecture audit on codebases by mapping module dependencies and checking layering integrity. It identifies structural decay using principles from classic engineering books. The tool generates Mermaid dependency graphs, assesses testability seams, and applies Conway's Law checks to ensure architectural health. It is suitable for developers needing to understand codebase structure, review folder organization, or detect circular imports before refactoring.
