BugAgent

This agent use Generative AI to determine the cause of an error, suggest a fix and even modify the faulty code.

The agent will start from the stacktrace and then read the code of every function involved to get more context. Then it will explain the error and suggest a fix in a report.

The fix can also be automatically made in-place.

The pulls requests of this repository are example of fix made by the agent: https://github.com/Aschen/bug-agent-llm/pulls

Usage

Import the agent and catch an error with the handleErrorWithAgent function.

app.post('/tasks', (req, res) => {
  try {
    createTask(req, res);
  }  
  catch (error) {
    handleErrorWithAgent(error, { modify: true, verbose: true });
    throw error;
  }
});

Try yourself

Run one of the example app: npx ts-node ./examples/context-understanding/app.js

Send a request: bash ./examples/context-understanding/create.sh

Example 1: error with context in 2 different files

This error is caused by accessing a property that does not exists on a object.
The property is accessed in the createTask function of app.js but is set in the addTask function of database.js.

The agent successfully suggest to return an updated task including the new property.

See the PR #1

(See example app directory)

// app.js
function createTask (req, res) {
  const newTask = req.body;
  verifyTask(newTask);
  const savedTask = database.addTask(newTask);
  res.status(201).send(`Task ${savedTask.metadata.id} saved successfully`);
}
// database.js
function addTask(newTask) {
  const tasks = readTasksFromFile();
  tasks.push({ ...newTask, metadata: { id: generateId() } });
  writeTasksToFile(tasks);
  return newTask;
}

Example 2: error that need a fix in 2 different files

The error is more or less the same but this time we need to update the 2 functions in order to solve it.

See the PR #2

(See example app directory)

// app.js
function createTask (req, res) {
  const newTask = req.body;
  verifyTask(newTask);
  database.addTask(newTask);
  res.status(201).send(`Task ${newTask.metadata.id} saved successfully`);
}
// database.js
function addTask(newTask) {
  const tasks = readTasksFromFile();
  tasks.push({ ...newTask, metadata: { id: generateId() } });
  writeTasksToFile(tasks);
}
