Language Specialists Agents
A curated collection of 11 language specialists agents for building with AI coding agents.
C# Pro
Use this agent for modern C#/.NET 8+ — records, pattern matching, nullable reference types, correct async/await, LINQ, Span<T>, and source generators — plus ASP.NET Core and EF Core. Examples — building a minimal-API service, fixing an EF Core N+1 or tracking leak, hunting a deadlock from sync-over-async, or turning on nullable reference types across a project.
Golang Pro
Use this agent for idiomatic Go — concurrency, errors, small interfaces, stdlib-first design, and profiling. Examples — fixing a goroutine leak, designing a context-aware API, profiling a hot path with pprof.
Java Pro
Use this agent for idiomatic, modern Java (17/21+) — records, sealed types, pattern matching, virtual threads and structured concurrency, the Streams API, and JVM/GC performance. Examples — modernizing a legacy POJO-and-thread-pool service to records and virtual threads, diagnosing a GC pause or allocation hotspot, reviewing concurrency correctness, or fixing a Spring Boot service that blocks the wrong threads.
Kotlin Pro
Use this agent for idiomatic Kotlin — null safety, coroutines and structured concurrency, Flow, sealed classes with exhaustive when, data classes, and extension functions — on Android and the JVM. Examples — fixing a coroutine leak, replacing callbacks with Flow, removing !! null-safety holes.
Php Pro
Use this agent for idiomatic, modern PHP 8.3+ — strict types, enums, readonly and promoted properties, Composer/PSR-4 autoloading, and safe PDO data access. Examples — modernizing a PHP 5-era class, killing an ORM N+1, hardening a query against SQL injection.
Python Pro
Use this agent for idiomatic, performant Python — typing, async, packaging, and stdlib mastery. Examples — refactoring to idiomatic Python, async I/O, packaging a library.
React Specialist
Use this agent for React architecture — hooks, state, performance, Server Components, and patterns. Examples — fixing re-render issues, designing component state, adopting RSC.
Rust Pro
Use this agent for idiomatic Rust — ownership, lifetimes, error handling, traits, async with tokio, and the cargo toolchain. Examples — fixing borrow-checker errors, designing a trait API, making async code compile cleanly under tokio.
SQL Pro
Use this agent for SQL itself — correct joins and window functions, indexing, EXPLAIN plans, schema design, and safe migrations on Postgres/MySQL. Examples — making a slow query fast, designing a normalized schema, writing a reversible migration.
Swift Pro
Use this agent for modern Swift 6 — value semantics, optionals done right, async/await and actors, Sendable/data-race safety, and idiomatic SwiftUI. Examples — fixing a data race under strict concurrency, untangling force-unwrap crashes, making a SwiftUI list scroll smoothly.
Typescript Pro
Use this agent for advanced TypeScript — generics, type-level programming, strictness, and inference. Examples — typing a tricky API, fixing type errors, designing a type-safe library surface.
