# TypeAgent

**TypeAgent** is **sample code** that explores an architecture for using [TypeChat](https://github.com/microsoft/typechat) to build a _personal agent_ with a _natural language interface_.

**TypeAgent** uses TypeChat to build a set of application agents that **take actions**. Agents define actions using TypeChat schemas.

The TypeAgent repo contains the personal agent and example application agents, along with internal packages used to build them.

## Examples

- Application agents with natural language interfaces:

  - [Music Player](./ts/packages/agents/player/)
  - [Chat](./ts/packages/agents/chat/)
  - [Browser](./ts/packages/agents/browser/)
  - [VS Code](./ts/packages/agents/code/)
  - [List Management](./ts/packages/agents/list/)
  - [Calendar](./ts/packages/agents/calendar/)
  - [Email](./ts/packages/agents/email/)
  - [Desktop](./ts/packages/agents/desktop/)

- [Agent Dispatcher](./ts/packages/dispatcher/)

  Explores applying TypeChat to route user requests to agents whose typed contract best matches user intent. Main component of the personal agent.

- [Agent Cache](./ts/packages/cache/)

  Explores how TypeChat translations from user intent to actions can be cached, minimizing the need to go the LLM.

- [Agent Shell](./ts/packages/shell/)

  An Electron application for interacting with multiple registered agents using a single unified user interface. Agent Shell includes:

  - Integrated chat experience with voice support
  - Dispatcher that dispatches to registered agents
  - Structured memory
  - Structured RAG

### State Management

Storage, registration, chat, memory and other state maintained by examples is **_typically_** stored **_locally_** in **your user folder** on your development machine. State is typically saved as ordinary text or JSON files in sub-folders below your user folder.

Example agents that use the Microsoft Graph or similar external services may store state in those services.

## Intended Uses

- TypeAgent is sample code shared to encourage the exploration of natural language agent architectures using TypeChat.
- Sample agents are not intended to be implemented in real-world settings without further testing/validation.

## Limitations

TypeAgent is early stage sample code over TypeChat. TypeAgent is not a framework. All code in this repo is intended for building our own example apps and agents only.

- TypeAgent is in **active development** with frequent updates and refactoring.
- TypeAgent has been tested with Azure Open AI services on developer's own machines only.
- TypeAgent is currently tested in English. Performance may vary in other languages.
- TypeAgent relies on [TypeChat](https://github.com/microsoft/typechat), which uses schema to validate LLM responses. An agent's validity therefore depends on how well _its schema_ represents the user intents and LLM responses _for its domains_.
- You are responsible for supplying any **API keys** for services used by examples.

## Getting Started

TypeAgent is written in TypeScript and relies on TypeChat. To understand how TypeAgent examples work, we recommend getting comfortable with TypeChat and [TypeChat examples](https://github.com/microsoft/TypeChat/tree/main/typescript/examples) first.

### Quick start - Agent Shell Example

The main entry point to explore TypeAgent is the [Agent Shell](./ts/packages/shell) example.

Follow these quick starts for step-by-step instructions to quickly setup tools and environments from scratch to build, run and develop.

- [Windows](./docs/setup/setup-Windows.md)
- [WSL2](./docs/setup/setup-WSL2.md)
- [Linux (Ubuntu/Debian)](./docs/setup/setup-Linux.md)
- MacOS (coming soon)

See the [instructions](./ts/README.md) in the TypeScript code [directory](./ts) for more detailed setup instructions.

## Developers

Microsoft TypeAgent Repo is a mono-repo, with components organized with the following root folders based on language used.

- [`ts`](./ts) TypeScript code ([Readme](./ts/README.md))
- [`python`](./python) Python code ([Readme](./python/README.md))
- [`dotnet`](./dotnet) Dotnet (C#) code ([Readme](./dotnet/README.md))

For developer who want to experiment with TypeAgent and see how typed action schema drives actions, the [Agent Shell](./ts/packages/shell) example allow additional agent to be installed/registered to extent functionality. The `Echo` agent [tutorial](./docs/tutorial/agent.md) is a starting point to create a plugin agent, and [Agent SDK](./ts/packages/agentSdk/) provides the details of the interface between [Dispatcher](./ts/packages/dispatcher) and the agent.
