GitHub Coding Agent is seamlessly embedded within GitHub, and developers can assign it tasks via GitHub issues or prompts in VS Code. Once assigned, the agent uses GitHub Actions to create a secure and fully customizable development environment to execute its tasks. As it works, the agent pushes commits to a draft pull request, and developers can track the entire process through detailed session logs that showcase its reasoning and validation steps.

Claude Code is Anthropic’s developer-first AI agent built to revolutionize software engineering through natural language interaction. It runs directly inside your terminal, giving developers a fast, privacy-conscious, and deeply integrated assistant for understanding, editing, and managing massive codebases. By indexing entire projects, Claude Code can instantly explain architectures, dependencies, and functions—ideal for onboarding, debugging, and modernization. It connects seamlessly with GitHub, GitLab, deployment tools, databases, and monitoring systems, letting developers control their workflows end-to-end without switching contexts. Using advanced Claude models such as Sonnet 4.5 and Opus 4.1, it performs complex reasoning to handle multi-file edits, refactoring, and PR creation with remarkable precision. Developers can run prompts like “Refactor this API handler for better error handling” or “Explain the structure of this repository” and receive actionable, context-aware results within seconds. It supports secure local execution with Node.js 18+, respecting existing permissions and workflows. Available under Pro and Max plans, Claude Code scales from solo developers to enterprise teams managing vast monorepos. Its goal is to make coding as fluid and intuitive as thinking, collapsing the distance between idea and implementation. In short, Claude Code brings the power of Claude’s reasoning directly to the command line, empowering developers to build faster and smarter.
