Practical overview

When it fits

Use it when agent development needs configurable environments and toolkits, with evaluation and benchmarking included in the workflow.

Who it is for

  • Developers creating autonomous agents for specific tasks.
  • Teams building agent tools or environments.
  • Practitioners benchmarking agent behavior.

Documented uses

  • Configure and build a custom autonomous agent.
  • Develop tools and environments for an agent task.
  • Run agents and benchmark their behavior.
Before you choose

Requirements & limits

  • The framework is organized around agent configurations, environments and toolkits.
  • Its documented scope includes building, running and evaluating agents.
  • The evaluation framework supports benchmarking agent behavior.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install and configure Youtu-agent for a first run

Set up the project, configure an LLM API key, and start the simple search agent.

Before you start

  • Python 3.12 or higher
  • Git
  • UV package manager
  • An API key for an LLM provider, such as DeepSeek

Steps

  1. Clone the project with the command below and enter its directory with cd youtu-agent.

    Documented command
    git clone https://github.com/TencentCloudADP/youtu-agent.git

  2. Install UV using a documented installation method, then create and activate a virtual environment with the command below and the activation command for your operating system.

    Documented command
    uv venv

  3. Install dependencies with the command below.

    Documented command
    uv sync --group dev

  4. Copy .env.example to .env and configure the required UTU_LLM_TYPE, UTU_LLM_MODEL, UTU_LLM_BASE_URL, and UTU_LLM_API_KEY values for your provider.

  5. Start the simple search agent with the command below. Type quit, exit, or q to end the conversation.

    Documented command
    python scripts/cli_chat.py --config_name simple/search_agent.yaml

Expected outcome

The simple search agent starts in the terminal and accepts questions for a conversation.

Guide limitations

  • Serper and Jina API keys are optional; some features may not work without them.
  • If errors occur, the guide recommends checking that the UV environment is activated and the UTU_LLM_* API key is configured correctly.

Source-based practical guide

Create and run a custom simple agent

Define a simple agent with the builtin search toolkit and use it from a Python script.

Before you start

  • A set-up Youtu-agent project with dependencies installed
  • An LLM API key configured in .env

Steps

  1. Create configs/agents/my_agents/my_first_agent.yaml with defaults loading the base model and builtin search toolkit, and set the agent name and instructions.

  2. Create a Python script that imports asyncio and SimpleAgent from utu.agents, opens SimpleAgent(config="my_agents/my_first_agent.yaml") in an async context, and calls agent.chat(...).

  3. Run the script and try a question supported by the configured agent, such as asking it to search for the latest tech news.

Expected outcome

The script starts the configured simple agent and submits a chat question.

Guide limitations

  • The example requires an LLM API key; search-related features may depend on optional tool API keys such as Serper or Jina.
  • The guide provides an example question but does not specify a guaranteed response or test result.
