GitLab Duo Agent Platform with Claude accelerates development

Introduces the concept of external agents within the GitLab Duo Agent Platform, allowing integration with external AI models like Claude and OpenAI's Codex. Demonstrates three use cases: generating a full-stack Java web application from an issue description, performing comprehensive code reviews on generated code, and creating a CI/CD pipeline to build a container image. Highlights the ability of these agents to understand project context, adhere to standards, and autonomously handle complex tasks across the development lifecycle.
