Visual Studio Code

Codex lacks a VSCode plugin and is cloud/GitHub-bound, forcing developers to work outside their normal IDE workflows. This makes the tool feel clunky compared to IDEs with integrated AI coding features.

Codex shows diffs and allows review but lacks an integrated code editor for quick inline tweaks during the review process. Developers must either request the agent to fix issues (30-60 second round trip), context-switch to VS Code, or lose momentum by staging changes for later.
