## What it does

The plugin installs a collection of subagents into Claude, each tied to one language or ecosystem. Inside you get `angular-architect`, `cpp-pro`, `csharp-developer`, `django-developer`, `dotnet-core-expert`, `dotnet-framework-4.8-expert`, `elixir-expert`, `expo-react-native-expert`, `fastapi-developer`, `flutter-expert`, `golang-pro`, `java-architect`, `javascript-pro`, `kotlin-specialist` and more. The source list is cut off, so check the repository for the full set.

Each subagent is a file describing when to call it and what it covers. `golang-pro` handles goroutines and channels, `django-developer` knows the ORM and async views, `fastapi-developer` works with Pydantic v2 and SQLAlchemy 2.0. Invocation uses the normal Claude subagent mechanism: the agent picks one, or you ask for it by name.

Worth installing if your project spans several languages and you want answers that don't blur together. For a single language the gain is smaller: `golang-pro` knows nothing the model doesn't, it just frames the answer.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add VoltAgent/awesome-claude-code-subagents
```
In the agent chat (not a shell):
```text
/plugin install voltagent-lang@voltagent-subagents
```

## When to use it
- untangle goroutines and channels in Go
- move Django views to async
- build a typed FastAPI service with Pydantic v2
- ship an Expo and React Native app
- keep a .NET Framework 4.8 codebase running without a rewrite

## Example prompts
- ask golang-pro to walk through this goroutine code
- call django-developer and check the ORM queries
- use fastapi-developer to rewrite validation with Pydantic v2
