Using Amazon Q Developer for GitHub

Amazon Q Developer1 is an AI-powered assistant that integrates directly into your GitHub workflow, enhancing your development process with intelligent features for code development, review, and transformation.

Slash Commands

Command Description
/q <message> Chat with the agent to ask questions or request revisions
/q review Requests an Amazon Q powered code review
/q help Displays usage information

Features

Agentic Chat
Enables interactive conversation with Amazon Q to ask questions about the pull request or request specific revisions. Use /q <message> in comment threads or the review body to engage with the agent directly.

Code Review
Analyzes pull requests for code quality, potential issues, and security concerns. Provides feedback and suggested fixes. Automatically triggered on new or reopened PRs (can be disabled for AWS registered installations), or manually with /q review slash command in a comment.

Customization

You can create project-specific rules for Amazon Q Developer to follow:

  1. Create a .amazonq/rules folder in your project root.
  2. Add Markdown files in this folder to define rules (e.g., cdk-rules.md).
  3. Write detailed prompts in these files, such as coding standards or best practices.
  4. Amazon Q Developer will automatically use these rules when generating code or providing assistance.

Example rule:

All Amazon S3 buckets must have encryption enabled, enforce SSL, and block public access.
All Amazon DynamoDB Streams tables must have encryption enabled.
All Amazon SNS topics must have encryption enabled and enforce SSL.
All Amazon SNS queues must enforce SSL.

Feedback

To provide feedback on Amazon Q Developer, create an issue in the Amazon Q Developer public repository.

Security Review Summary

This PR introduces a JavaScript file with critical security vulnerabilities that must be addressed before merge:

🚨 Critical Issues Found:

  1. Hardcoded Database Credentials - Database username and password are exposed in source code
  2. Multiple SQL Injection Vulnerabilities - Direct string interpolation in SQL queries across 6+ endpoints
  3. Command Injection Vulnerabilities - Unsanitized user input passed to spawn() commands
  4. Plaintext Password Storage - Student passwords stored without hashing

🔒 Security Impact:

  • High Risk: SQL injection could lead to complete database compromise
  • High Risk: Command injection could allow arbitrary code execution on the server
  • Medium Risk: Hardcoded credentials expose database access
  • Medium Risk: Plaintext passwords compromise user accounts

✅ Required Actions:

All security vulnerabilities must be fixed with the provided code suggestions before this PR can be merged. The fixes include using parameterized queries, input validation, environment variables for credentials, and proper password hashing.

Status: ❌ CHANGES REQUESTED - Critical security vulnerabilities block merge


You can now have the agent implement changes and create commits directly on your pull request's source branch. Simply comment with /q followed by your request in natural language to ask the agent to make changes.
