Skill UI

This skill provides comprehensive guidance on implementing high-performance, non-blocking applications in Python. It utilizes asyncio, async/await, and advanced concurrency patterns to handle I/O-bound workloads efficiently. Ideal for building async web APIs, real-time systems, and concurrent data processing.

Master secure authentication and authorization implementation using industry-standard patterns. Covers user login systems, REST/GraphQL API security, OAuth2, SSO, session management, and RBAC design. Includes guidance on token lifecycle, secrets storage, and threat modeling to protect resource access boundaries effectively.

Design patterns for building autonomous coding agents, covering tool and function calling APIs, permission and approval systems, browser automation, and human-in-the-loop workflows inspired by Cline and OpenAI Codex.

Autonomous agents are AI systems capable of independently decomposing goals, planning actions, executing tools, and self-correcting without constant human guidance. This skill focuses on ensuring reliability in agent loops like ReAct and Plan-Execute, emphasizing goal decomposition and reflection patterns. It highlights that compounding error rates can kill autonomy, advocating for constrained, domain-specific agents over general autonomy. Build for reliability first.

Build server-side call automation workflows using Azure Communication Services Java SDK. Supports IVR systems, call routing, recording, and AI-powered speech interactions. Includes DTMF recognition, text-to-speech, and webhook event handling for enterprise communication solutions.

Expert backend architect for scalable API design, microservices, distributed systems, resilience, security, and observability.

This skill guides the construction of robust, production-grade backtesting systems for financial trading strategies. It helps users systematically validate performance, avoid common biases (like look-ahead bias), and implement advanced techniques such as walk-forward analysis, ensuring reliable performance estimates before live deployment.

This skill enables modeling agent mental states using BDI architecture. It transforms RDF context into beliefs, desires, and intentions, supporting cognitive reasoning and explainability in multi-agent systems. It facilitates logic augmented generation and temporal state tracking for rational agency.

Master Bevy's Entity Component System (ECS) in Rust, covering Systems, Queries, Resources, and parallel scheduling. Ideal for building high-performance game logic and optimizing data-oriented architectures.

This skill provides comprehensive automation for managing complex subscription billing lifecycles. It handles recurring billing, generating detailed invoices, managing failed payment recovery (dunning), calculating prorated adjustments, and ensuring accurate tax compliance (VAT, GST). Use it for implementing full SaaS subscription billing systems and automating core financial billing processes.

Expert blockchain developer for production-grade Web3 applications, smart contracts, and decentralized systems. Covers DeFi protocols, NFT platforms, DAOs, and enterprise blockchain integration with security best practices.

Learn to implement zero-downtime deployment strategies for production systems. This skill covers blue-green, canary, and rolling deployments using Kubernetes, AWS ECS, and Istio. Includes configuration for load balancers, health checks, and traffic switching scripts to ensure seamless updates without service interruption.
