What Devin Desktop and Codex Each Bring to the Table
Devin Desktop provides the current editor and agent-management workspace built on the Windsurf IDE foundation. The Codex IDE extension provides an in-editor path for focused repository tasks, while Codex CLI remains the terminal-led option.
For another extension-based setup, compare the VS Code workflow and the Cursor workflow.
Install Codex in Devin Desktop
- Download or update Devin Desktop. Existing Windsurf users receive the new name through the normal update path.
- Open the intended repository.
- Install or enable the official OpenAI Codex extension.
- Sign in through the supported ChatGPT flow.
- Choose the Codex icon. If it is not visible, open the Command Palette and run
Codex: Open Codex Sidebar. - Ask for a repository explanation with zero edits before requesting a change.
Try: "Map the registration route to its components and data calls. Do not change any file."
Expected success: the sidebar opens and the response names files in the active repository. If the command is missing, confirm that the extension is enabled, reload Devin Desktop, and reopen the workspace.
A Typical Devin Desktop Session
Begin with one visible outcome, such as preventing a duplicate form submission. Ask Codex to trace the relevant files and return a plan. Approve one bounded edit, review the diff in Devin Desktop, run the related test, and open the route to verify the reported state.
Request a structured handoff: "Return changed files, test command, result, visual check, and anything skipped."
Getting Better Results From the Pairing
Keep one objective per task, name the affected route or component, and define what must remain unchanged. Review the diff before accepting it. Create a Git checkpoint before and after the task so the change is easy to compare or revert.
Do not paste secrets, private account data, or production credentials into the editor chat.
