GitHub (Copilot, Claude and Codex agents)
Best for: Developers who want an issue to come back as a pull request
On GitHub you assign an issue to Copilot's cloud agent, or to the Claude and Codex coding agents, which are in public preview. The agent works in its own environment, opens a pull request and requests your review when it finishes, and you steer it by commenting. Where it wins: the review step is the pull request you already use, and Copilot, Claude and Codex can all work on the same repository. The catch: it's for code in GitHub repositories only, the cloud agent starts at Copilot Pro and Claude and Codex at Pro+, and sessions use Actions minutes and AI credits.
