Open source terminal agent

Your AI coding agent.
Right in your terminal.

TARS reads your codebase, plans the change, writes the code, runs the commands, and verifies the result — streaming every step into an interactive terminal UI.

How it works

From prompt to working code.

One loop runs until the model returns a final answer with no tool calls left to make.

01
Prompt
You describe the task
02
Understand
read + bash inspect the project
03
Plan
The model drafts the approach
04
Code
edit and write apply changes
05
Run
bash executes the commands
06
Verify
Results feed back into the loop
