Identify bugs with root cause analysis, confidence scores, and actionable fix suggestions. Your AI-powered debugging assistant.
The Debug tool performs deep analysis of your code to identify bugs, explain their root causes, and suggest fixes:
Identifies logic errors, type mismatches, null pointer issues, race conditions, memory leaks, and other common bugs.
Explains why the bug occurs, not just what's wrong. Includes confidence scores to prioritize likely causes.
Provides corrected code with explanations. Use the Diff view to see exactly what changes are needed, then apply with one click.
Identifies potential side effects of fixes and suggests additional tests to prevent regressions.
The Debug tool accepts optional context to improve accuracy:
| Field | Description |
|---|---|
| Error Message | The error message you're seeing (e.g., TypeError, null reference) |
| Stack Trace | Full stack trace for better context on where the error occurs |
Include Error Details
Providing the actual error message and stack trace dramatically improves debugging accuracy. Copy them directly from your console or logs.
Click the Debug button (red icon) or pressCmd/Ctrl + 2.
Enter the code that's causing issues. Include enough context (imports, type definitions) for accurate analysis.
Expand the context section and paste your error message and/or stack trace for better diagnosis.
Run the analysis. ARKAbrain routes to high-quality models for deep reasoning on complex bugs.
Read the diagnosis, check the Diff tab to see proposed changes, and click "Apply Changes" to fix your code.
Here's a React component with a common bug:
import { useState, useEffect } from 'react';
function UserProfile({ userId }) {
const [user, setUser] = useState(null);
const [loading, setLoading] = useState(true);
useEffect(() => {
fetch(`/api/users/${userId}`)
.then(res => res.json())
.then(data => {
setUser(data);
setLoading(false);
});
}, []); // Bug: missing userId dependency
if (loading) return <div>Loading...</div>;
return (
<div>
<h1>{user.name}</h1>
<p>{user.email}</p>
</div>
);
}The Debug tool would identify:
userId in useEffect dependency arrayuserId to the dependency arraySecurity Bugs
The Debug tool can identify security vulnerabilities like injection attacks and XSS. Always review suggested fixes carefully before deploying to production.
