StreetRace is an open-source platform for engineering-native AI agents that integrate with your tools, automate your workflows, and evolve with your development process.

StreetRace is a new kind of teammate: one that runs linters, generates modules, monitors builds, or triages bugs the way you taught it.

We believe the future of development is peer-to-peer: engineer + agent. And we’re building the rails.

If you want to help define that future - contribute code, build agents, or shape the platform - GitHub’s open. Jump in, clone it, and make agents your own.

StreetRace🚗💨

Unlike generic agent frameworks or black-box AI engineers, StreetRace is:

🔧 Built for Developers, by Developers

StreetRace integrates directly with your tools like the CLI and code editor (Dockerized environments will follow). Agents can operate in the same terminal and shell as their human counterparts, enabling seamless, trusted collaboration.

🤝 Engineering Peer, Not Replacement

Where Devin and other agents aim to replace engineers, StreetRace empowers engineers. Your agent isn't a shadow coder, it’s a co-worker you can inspect, guide, and evolve.

🧩 Opinionated, Yet Extensible

Unlike CrewAI’s generic orchestration layer, StreetRace comes powered by ADK, provides built-in A2A publishing, and integrates with any MCP tools. It comes with battle-tested patterns and tools for building high-performing agents. Developers can publish reusable agents to automate routine tasks like onboarding codebases, responding to CI failures, or generating service templates.

🛠 Open, Flexible, and Secure

Model-agnostic and open-source, StreetRace supports everything from local Ollama models to cloud APIs. Agents run in the local environment, with controlled APIs (A2A endpoints), giving teams full control, observability, and security.

Getting Started

Development Environment

For the best development experience, use the VS Code Dev Container which includes:

• Enhanced terminal with persistent bash history and autocompletion
• Command shortcuts like gs (git status), pi (poetry install), check (make check)

To get started:

1. Install the Dev Containers extension
2. Open the project in VS Code
3. Click "Reopen in Container" when prompted
4. Type help in the terminal to see all available commands and aliases

Installation and usage

Install from PyPI

Using pipx (follow pipx installation instructions here.)

$ pipx install streetrace

Or using pip to install as project dependency:

$ pip install streetrace

Install from source

The code is managed by poetry. If it's not already installed, follow the poetry install guide.

$ git clone git@github.com:krmrn42/street-race.git
$ cd street-race
$ poetry install
$ poetry run streetrace --model=$YOUR_FAVORITE_MODEL

Where $YOUR_FAVORITE_MODEL is the LiteLLM provider route (provider/model).

Environment Setup

Follow relevant LiteLLM guides to set up environment for a specific model. For example, for commercial providers, set your regular API key in the environment (ANTHROPIC_API_KEY, GEMINI_API_KEY, OPENAI_API_KEY, etc), or OLLAMA_API_URL for local Ollama models.

Usage

streetrace is a CLI, and it can be installed as your dev dependency. It runs in the current directory, keeping all file reading and modifications in the current directory.

You can optionally supply a --path argument to provide a different working directory path.

$ streetrace --model=$YOUR_FAVORITE_MODEL
You: Type your prompt

Try in your environment

Currently, StreetRace includes one coding agent with a model of your choise. This agent is a capable software engineering agent that can work with your technology stack.

You can add more context to your prompts in two ways:

1. Use @-mentions, autocomplete will suggest local files that you can add to the prompt.
2. Add project context and instructions in the .streetrace folder in your project's directory:
   • SYSTEM.md is used as your system instruction.
   • Any other files under .streetrace are added as initial conversation messages.

Command Line Arguments

Help Information

You can view all available command-line arguments and their descriptions:

$ streetrace --help
# or
$ streetrace -h

This displays the complete usage information, including all available options and their descriptions.

Version Information

You can check the installed version of StreetRace:

$ streetrace --version
StreetRace🚗💨 0.1.13

Session Management

StreetRace supports persistence of conversations through sessions. You can specify:

• --app-name - Application name for the session (defaults to the current working directory name)
• --user-id - User ID for the session (defaults to your GitHub username, Git username, or OS username)
• --session-id - Session ID to use or create (defaults to current timestamp)
• --list-sessions - List all available sessions for the current app and user

Examples:

# List all sessions for the current app and user
$ streetrace --list-sessions

# Create or continue a specific session
$ streetrace --session-id my-project-refactoring

# Work with a specific app name and user
$ streetrace --app-name my-project --user-id john.doe --session-id feature-x

If no session arguments are provided, StreetRace will:

1. Use the current working directory name as the app name
2. Use your detected user identity as the user ID
3. Create a new session with a timestamp-based ID

This allows you to maintain separate conversation contexts for different projects or tasks.

If you want to work with the same agent/context across multiple runs, use the same session ID.

Working with Files in Another Directory

The --path argument allows you to specify a different working directory for all file operations:

$ streetrace --path /path/to/your/project

This path will be used as the working directory (work_dir) for all tools that interact with the file system, including:

• list_directory
• read_file
• write_file
• find_in_files
• as a cwd in cli commands.

This feature makes it easier to work with files in another location without changing your current directory.

Interactive Mode

When run without --prompt, StreetRace enters interactive mode.

Autocompletion

• Type @ followed by characters to autocomplete file or directory paths relative to the working directory.
• Type / at the beginning of the line to autocomplete available internal commands.

Internal Commands

These commands can be typed directly into the prompt (with autocompletion support):

• /help: Display a list of all available commands with their descriptions.
• /exit: Exit the interactive session.
• /quit: Quit the interactive session.
• /history: Display the conversation history.
• /compact: Summarize conversation history to reduce token count.
• /reset: Reset the current session, clearing the conversation history.

For detailed information about the /compact command, see docs/commands/compact.md.

Non-interactive Mode

You can use the --prompt argument to run StreetRace in non-interactive mode:

$ streetrace --prompt "List all Python files in the current directory"

This will execute the prompt once and exit, which is useful for scripting or one-off commands.

CLI Command Safety

StreetRace includes an experimental safety mechanism for CLI command execution. Each command requested by the AI is analyzed and categorized into one of three safety levels:

• Safe: Commands from a pre-configured safe list with only relative paths
• Ambiguous: Commands not in the safe list but without obvious risks
• Risky: Commands with absolute paths, directory traversal attempts, or potentially dangerous operations

Risky commands are blocked by default to prevent unintended filesystem operations or system changes. This adds a layer of protection when working with AI-suggested commands.

The safety checker uses bashlex to parse and analyze commands and arguments, checking for:

• Command presence in a predefined safe list
• Use of absolute vs. relative paths
• Directory traversal attempts (using .. to move outside the working directory)

This helps ensure that StreetRace operates within the intended working directory and with known-safe commands.

Agent System

StreetRace includes a modular agent system that allows for specialized agents to be discovered and used.

Agent Discovery

The list_agents tool allows the assistant to discover available agents in the system. Agents are searched for in the following locations:

• ./agents/ (relative to the current working directory)
• ../../agents/ (relative to the src/streetrace/app.py)

Creating Custom Agents

StreetRace supports two ways to create custom agents:

Option 1: Using the StreetRaceAgent Interface (Recommended)

1. Create a directory for your agent in the ./agents/ folder (e.g., ./agents/my_agent/)

2. Create an agent.py file with a class that inherits from StreetRaceAgent and implements:

   • get_agent_card() - Returns metadata about the agent (name, description, capabilities)
   • get_required_tools() - Returns a list of tools the agent needs
   • create_agent() - Creates the actual agent instance with the provided model and tools

3. Add a README.md file with documentation for your agent

Example agent class:

from streetrace.agents.street_race_agent import StreetRaceAgent
from streetrace.agents.street_race_agent_card import StreetRaceAgentCard

class MyAgent(StreetRaceAgent):
    def get_agent_card(self) -> StreetRaceAgentCard:
        return StreetRaceAgentCard(
            name="My Agent",
            description="A specialized agent that does something useful",
            capabilities=["capability1", "capability2"],
        )

    async def get_required_tools(self) -> list[str]:
        return [
            "streetrace:fs_tool::read_file",
            "streetrace:fs_tool::write_file",
        ]

    async def create_agent(self, model_factory, tools) -> BaseAgent:
        model = model_factory.get_default_model()
        return Agent(
            name="My Agent",
            model=model,
            description="My specialized agent",
            instruction="You are a specialized agent that does X, Y, and Z...",
            tools=tools,
        )

Option 2: Legacy Approach (Basic Functions)

1. Create a directory for your agent in the ./agents/ folder (e.g., ./agents/my_agent/)

2. Create an agent.py file with these required functions:

   • get_agent_metadata() - Returns a dictionary with name and description keys
   • run_agent(input_text: str) - Implements the agent's functionality

3. Add a README.md file with documentation for your agent

Running Agents

The run_agent tool allows the primary assistant to execute specialized agents:

run_agent(
    agent_name="Hello World",
    input_text="What files are in this directory?",
    model_name="default"  # Optional, defaults to the default model
)

This enables a hierarchical agent system where the primary StreetRace assistant can delegate tasks to specialized agents.

Tool Configuration

Tools available to agents are defined in the ./tools/tools.yaml configuration file. This file specifies:

• Tool name and description
• Source type (e.g., 'local' for Python modules or 'mcp' for external services)
• Module and function name for local tools
• Whether the tool requires agent capabilities

The configuration makes it easy to add, modify, or disable tools without changing code.

Tool Discovery

The list_tools tool provides information about available tools that can be provided to agents. This helps the assistant understand what capabilities are available in the system.

The tool returns a list of available tools with:

• Tool name
• Description
• Whether the tool requires agent capabilities
