  • Automated unit test generation: Use the /test agentic command to have Amazon Q autonomously generate comprehensive unit tests for a function or module, including edge cases.
  • Security vulnerability scanning & remediation: Run inline security scans during development to detect CVEs, OWASP issues, and CWEs across languages like Python, Java, JavaScript, and TypeScript — with fix suggestions applied directly to code.
  • Java and .NET application modernization: Leverage transformation agents to upgrade Java 8/11 apps to Java 17 and port .NET Windows applications to Linux, reducing manual migration effort at scale.
  • Custom code recommendations via private repo indexing: Connect internal repositories to generate context-aware suggestions tailored to your company's coding patterns, APIs, and internal libraries.
  • CLI automation with natural language: Use the Amazon Q CLI to translate plain English instructions into shell commands, accelerating DevOps scripting and AWS resource management from the terminal.
  • Agentic feature implementation: Trigger multi-step autonomous coding workflows that read existing code, implement a new feature end-to-end, generate diffs, and incorporate developer feedback in real time.
