Build voice applications using TeXML markup language (TwiML-compatible). Manage applications, calls, conferences, recordings, queues, and streams. This skill provides Ruby SDK examples.
Manage WebRTC credentials and mobile push notification settings. Use when building browser-based or mobile softphone applications. This skill provides Ruby SDK examples.
Stream call audio in real-time, fork media to external destinations, and transcribe speech live. Use for real-time analytics and AI integrations. This skill provides REST API (curl) examples.
Transform slow database queries into lightning-fast operations through systematic optimization, proper indexing, and query plan analysis.
Create and manage NocoBase data models via MCP. Use when users want to inspect or change collections, fields, relations, or view-backed schemas in a NocoBase app.
Build and integrate Manifest DEX on Solana using the Manifest SDK. Covers market reads, order placement, wrapper and global account setup, reverse and global order types, and frontend integration patterns.
Go interface design patterns: implicit interfaces, consumer-side definition, interface compliance verification, composition, the accept-interfaces-return-structs principle, and common pitfalls. Use when designing interfaces, decoupling packages, defining contracts, reviewing interface usage, or refactoring for testability. Trigger examples: "design interface", "accept interfaces return structs", "interface compliance", "consumer-side interface", "interface composition". Do NOT use for HTTP handler patterns (use go-api-design) or general code review (use go-code-review).
Guide for creating and organizing FastAPI routes using a file-based routing system or modular router pattern. Helps organize complex API structures.
Build terminal UIs with Bubbletea, Bubbles, Lipgloss, and Huh. Use when creating TUI applications, interactive forms, styled terminal output, or when user mentions Bubbletea, Bubbles, Lipgloss, Huh, Charm, or TUI development.
Comprehensive reference for all 38 Symfony framework components with PHP 8.3+ and Symfony 7.x patterns. Use when the user asks to implement, configure, or troubleshoot any Symfony component including HttpFoundation, HttpKernel, DependencyInjection, Form, Validator, Cache, Messenger, Console, EventDispatcher, Workflow, Serializer, Security, Routing, Twig, Doctrine integration, or any other Symfony component. Covers APIs, configuration, best practices, and common pitfalls.
Advanced Rust patterns for ownership, traits, async, error handling, macros, type system tricks, unsafe, and performance. Use when tackling complex Rust problems — not basic syntax, but multi-concern tasks like designing cancellation-safe async services, choosing between trait objects and generics, building typestated APIs, structuring error hierarchies across crate boundaries, writing proc macros, or optimizing hot paths with zero-cost abstractions. Do not use for basic Rust syntax, simple CLI tools, or beginner ownership questions.
Advanced Effect-TS patterns for typed errors, dependency injection, concurrency, resource management, schema validation, and streaming. Use when building Effect programs — not simple Effect.succeed/fail questions, but multi-concern tasks like designing service layers with Layer composition, handling typed error hierarchies with tagged errors, managing concurrent fibers with structured concurrency, scoped resource lifecycles, schema-driven API contracts, or integrating Effect with existing Express/Hono/database stacks. Do not use for basic TypeScript or general functional programming questions.
