red: Vim keys. Agent inside. One binary.

Space A

The agent works through your editor.

Codex sees what you see: open buffers, unsaved changes, the selection, and the diagnostics. Its edits go through Red's editor transactions and save paths, never behind your back.

Reads the live buffer, including edits you haven't saved.
Changes are revision-checked and confined to the workspace.
Every edit is attributed to its conversation, and you can resume it later.

Ask about this line. Not the whole repo.

Select the exact text, or let Red pick the enclosing function. The answer lands as one unsaved, undoable edit, so u takes it back.

Space G

Stage. Commit. Stay.

A full Git workspace inside the editor: hunks, staging, branches, remotes, stashes, logs, and rebases. Codex can write the commit message from the staged diff.
