Consult this skill for async Python patterns and concurrency. Use when building async APIs, concurrent systems, I/O-bound applications, implementing rate limiting, async context managers. Do not use when CPU-bound optimization - use python-performance instead. DO NOT use when: testing async code - use python-testing async module.
Standardized error handling patterns with classification, recovery, and logging strategies. error handling, error recovery, graceful degradation, resilience.
Senior Payment Solutions Architect for Stripe (2026). Specialized in secure checkout flows, complex billing models (usage-based/hybrid), global tax compliance via Stripe Tax, and high-performance Next.js 16 integration. Expert in building PCI-compliant, idempotent, and resilient payment systems using Checkout Sessions, Payment Elements, and Server Actions.
Exhaustive, source-accurate guide for building iMessage applications using @photon-ai/imessage-kit (Basic) and @photon-ai/advanced-imessage-kit (Advanced). Covers every method, type, option, event, and pattern for iMessage automation, AI agents, and chat bots.
Solidity smart contract development workflow. Use when modifying smart contracts in apps/eth-contracts/contracts/.
Micronaut framework guardrails, patterns, and best practices for AI-assisted development. Use when working with Micronaut projects, or when the user mentions Micronaut. Provides compile-time DI, HTTP server/client, data access, and cloud-native guidelines.
Build applications with the Yo Protocol SDK (`@yo-protocol/core`) — an ERC-4626 yield vault protocol supporting Ethereum (1), Base (8453), and Arbitrum (42161). Use when writing code that interacts with Yo Protocol vaults: preparing deposit/redeem transactions, checking positions, querying vault snapshots/yield/TVL, or claiming Merkl rewards. Triggers on mentions of Yo Protocol, yoETH, yoUSD, yoBTC, yoEUR, yoGOLD, yoUSDT, yo-protocol/core, YoClient, createYoClient, PreparedTransaction, or ERC-4626 vault interactions via the Yo gateway.
Set up a Stylus smart contract project with OpenZeppelin Contracts for Stylus on Arbitrum. Use when users need to: (1) install Rust toolchain and WASM target for Stylus, (2) create a new Cargo Stylus project, (3) add OpenZeppelin Stylus dependencies to Cargo.toml, or (4) understand Stylus import conventions and storage patterns for OpenZeppelin.
Concurrency: threads vs async, locks/mutexes/rwlocks, atomics, lock-free, actor model, STM, deadlock
Networks: TCP/IP, HTTP/2/3, TLS 1.3, DNS, BGP, WebSockets, QUIC, socket programming
Nim 2.x: macros, templates, compile-time, memory ARC/ORC, FFI, Nimble, systems programming
Use Litestar's event emitter and listener system with `@listener`, `request.app.emit()`, multiple listeners per event, multi-event listeners, shared argument contracts, and custom event emitter backends. Use when decoupling async side effects, fanout-style in-process notifications, or transport-triggered domain events inside a Litestar app. Do not use for startup/shutdown lifecycle hooks, request/response interception, or broker-backed pub-sub systems that belong in app setup, lifecycle hooks, or channels.
