Automatically start /ide in VS Code + Terminal environments

What variant of Codex are you using?

CLI

What feature would you like to see?

When Codex is running inside the VS Code integrated terminal, /ide should be enabled automatically.

Current behavior:

• User starts Codex from the VS Code integrated terminal.
• IDE integration is not enabled by default.
• User must manually run /ide in every new session.

Expected behavior:

• Codex detects that it is running inside VS Code.
• Codex automatically enables /ide on session startup.
• No manual /ide command is required.

Reason:

This is repetitive setup work that can be inferred from the environment. In VS Code + terminal usage, IDE integration is the expected default behavior, not an optional manual step.

Suggested implementation:

• Detect VS Code integrated terminal environment variables.
• Auto-run or auto-initialize /ide when the environment is detected.
• Optionally provide a config flag to disable this behavior.

Additional information

Reference behavior:

Claude Code handles IDE integration more automatically in this workflow. Codex should match this baseline UX.
