Reviews axum web framework code for routing patterns, extractor usage, middleware, state management, and error handling. Use when reviewing Rust code that uses axum, tower, or hyper for HTTP services. Covers axum 0.7+ patterns including State, Path, Query, Json extractors.
Search, order, and manage phone numbers by location, features, and coverage.
Manage port-out requests when numbers are being ported away from Telnyx. List, view, and update port-out status. This skill provides JavaScript SDK examples.
[Pragmatic DDD Architecture] How to structure **Use Cases** using DDD and Railway-Oriented Programming (neverthrow Result types). Tailored for TypeScript + drizzle-orm + node-postgres stack. **Use whenever creating or modifying any Use Case class — even simple ones like "Exists" or "List" operations — to ensure type-safe error unions, proper transactional boundaries, Value Object-only contracts, auth-first patterns, and Result-based error handling.** Includes references to working examples (Create, List, Exists patterns). Depends on 'repositories' skill.
[Pragmatic DDD Architecture] Guide for creating strictly typed Domain validation and infrastructure errors. Use when handling or creating new errors to ensure they conform to the Railway-oriented programming model (neverthrow Result), TypeScript error branding, and constructor parameter constraints. Covers co-location rules vs. shared domain error usage.
Identifies silent failures, inadequate error handling, and inappropriate fallback behavior in code. Zero tolerance for errors that occur without proper logging and user feedback. Triggers: When reviewing error handling, checking for silent failures, analyzing catch blocks. Examples: - "Review the error handling" -> audits all error handling in recent changes - "Check for silent failures" -> hunts for swallowed errors and empty catch blocks - "Analyze catch blocks in this PR" -> reviews every try-catch for adequacy - "Are there any hidden failures?" -> finds errors that get silently ignored
Guidelines for building production-ready Convex apps covering function organization, query patterns, validation, TypeScript usage, error handling, and the Zen of Convex design philosophy
Build with Firestore NoSQL database - real-time sync, offline support, and scalable document storage. Use when: creating collections, querying documents, setting up security rules, handling real-time listeners, or troubleshooting permission-denied, quota exceeded, invalid query, or offline persistence errors. Prevents 10 documented errors.
Guide AI agents through TypeScript coding best practices including type safety, error handling, code organization, and architecture patterns. This skill should be used when generating TypeScript code, reviewing TypeScript files, creating new TypeScript modules, refactoring JavaScript to TypeScript, or when the user asks about TypeScript patterns, types, or coding standards. Keywords: typescript, types, coding standards, best practices, type safety, generics, architecture, refactoring.
Rust systems programming patterns and style guide for building reliable systems software. This skill should be used when writing Rust code, especially for systems programming, CLI tools, or performance-critical applications. Covers project organization with Cargo workspaces, module structure, naming conventions (RFC 430), type/trait patterns (Option, builders, associated types), and error handling with thiserror/anyhow.
Use this skill BEFORE writing or editing any Go (.go) files. Triggers when about to create, modify, or add code to .go files. Enforces happy path coding, error wrapping, sentinel errors, and godoc-style comments.
Error handling patterns for robust applications. Use when implementing try-catch blocks, error boundaries, custom errors, or logging. Covers async errors, React error boundaries, and API error responses.
