Hello world
Fix a github issue with SWE-agent
In this tutorial, we will fix a github issue with SWE-agent using the command line interface.
- Make sure you have installed SWE-agent and have a language model set up.
- We will be executing code in a Docker sandbox, so make sure you have docker installed (docker troubleshooting). If you cannot run docker, skim this tutorial and see how you can run SWE-agent with cloud-based execution in the command line basics tutorial.
After installing SWE-agent, you have the sweagent
command available. Run sweagent --help
to see the list of subcommands.
The most important ones are
sweagent run
: Run SWE-agent on a single problem statement. This is covered on this page and for slightly more advanced examples in the command line basics tutorial.sweagent run-batch
: Run SWE-agent on a list of problem statements. This is what you would use for benchmarking, or when working with a larger set of historic issues. Covered in the batch mode tutorial.
In this tutorial, we will focus on the run
subcommand.
Let's start with an absolutely trivial example and solve an issue about a simple syntax error (swe-agent/test-repo #1
)
sweagent run \
--agent.model.name=claude-3-7-sonnet-latest \
--agent.model.per_instance_cost_limit=2.00 \
--env.repo.github_url=https://github.com/SWE-agent/test-repo \
--problem_statement.github_url=https://github.com/SWE-agent/test-repo/issues/1
The example above uses the Claude 3.5 Sonnet
model from Anthropic. Alternatively, you can for example use GPT-4o
(from OpenAI)
by setting --agent.model.name=gpt-4o
.
In order to use it, you need to add your keys to the environment:
export ANTHROPIC_API_KEY=<your key>
export OPENAI_API_KEY=<your key>
alternatively, you can create a .env
file in your working directory and put your keys in there like so:
ANTHROPIC_API_KEY=<your key>
OPENAI_API_KEY=<your key>
We should support all models that you can think of.

I've uploaded a python code repository in the directory /SWE-agent__test-repo. Consider the following PR description:
<pr_description>
SyntaxError: invalid syntax
I'm running `missing_colon.py` as follows:
```python
division(23, 0)
```
but I get the following error:
```
File "/Users/fuchur/Documents/24/git_sync/swe-agent-test-repo/tests/./missing_colon.py", line 4
def division(a: float, b: float) -> float
^
SyntaxError: invalid syntax
```
</pr_description>
Can you help me implement the necessary changes to the repository so that the requirements specified in the <pr_description> are met?
I've already taken care of all changes to any of the test files described in the <pr_description>. This means you DON'T have to modify the testing logic or any of the tests in any way!
Your task is to make the minimal changes to non-tests files in the /SWE-agent__test-repo directory to ensure the <pr_description> is satisfied.
Follow these steps to resolve the issue:
1. As a first step, it might be a good idea to find and read code relevant to the <pr_description>
2. Create a script to reproduce the error and execute it with `python <filename.py>` using the bash tool, to confirm the error
3. Edit the sourcecode of the repo to resolve the issue
4. Rerun your reproduce script and confirm that the error is fixed!
5. Think about edgecases and make sure your fix handles them as well
Your thinking should be thorough and so it's fine if it's very long.

ðĶ DEBUG Ensuring deployment is stopped because object is deleted
As you can see, the command line options are hierarchical. At the top level, there are three important sections:
problem_statement
: What problem are you trying to solve?agent
: How do you want to solve the problem? This includes setting up the LM with--agent.model
.env
: What is the environment in which the problem statement should be solved? This includes setting the repository/folder with the source files with--env.repo
, as well as docker images and other dependencies. This will also control where the code is executed (in a local container or in the cloud).
Watching the output, you can notice several stages:
- Setting up the deployment: SWE-agent lets LMs execute actions in sandboxed environments. It can run these environments
in docker containers (default), on modal, AWS fargate, or directly on your computer (not recommended).
When the deployment starts, you will notice a "starting runtime" message that takes a few seconds. The runtime is
what is executing the commands within your deployment.
Deployments are managed by a package called
SWE-ReX
. - Setting up tools: The tools that you specified are copied and installed within the environment.
- System and instance prompts: The initial instructions are shown to the LM. They are fully configurable.
- Main loop: The LM starts to suggest and execute actions.
- Submission: The LM calls
submit
and we extract the patch (i.e., the changes to the source code that solve the problem).
The complete details of the run are saved as a "trajectory" file). They can also be turned into new demonstrations together with other log and output files.
Wetted your appetite? Head over to the command line basics tutorial to learn more about the options.
