Practical guide

Codex app, CLI or IDE extension

The objective is to choose the right Codex surface by task and control requirement. The review baseline covers work location, context, automation, review and team standard.

WERKVERSTAND / CONNECTING INTELLIGENCE

The essential answer

Choose the Codex interface by workflow: desktop for projects and visual review, CLI for terminal and scripted work, IDE for work close to the editor. Check features and permissions concretely. Shared project rules do not mean every interface has identical capabilities.

01 / FIT

A good fit when

  • A concrete assignment and an accountable domain owner are defined.
  • A comparison of the same repository task records context transfer, required interventions and reviewability for each surface. Shared rules and acceptance criteria remain constant.

02 / LIMITS

Not the first choice when

  • Avoid: multiple surfaces without shared project rules. If each surface uses different project rules, the comparison cannot reliably separate interface differences from instruction differences.

Start from the normal working environment

The desktop app combines projects, files and visual review. The CLI works from a terminal and supports scripted use through codex exec. An editor-focused team can also consider the IDE extension. Compare the same small assignment and record which context needs additional explanation or transfer.

Distinguish scheduling from scripted execution

The current documentation says CLI and IDE do not have their own Scheduled management interface. Recurring tasks are managed in the designated web or desktop surfaces. A CLI script can be part of separately operated automation. That operation needs an owner, accessible files and failure handling; a non-interactive invocation alone does not provide them.

Create a reasoned team convention

Evaluate context transfer, clarification, diff review and adoption together. Establish shared repository rules with justified exceptions for specialised tasks. For example, development can remain in the editor while visual acceptance happens in the desktop app. The choice succeeds when hand-offs improve and testing and responsibility survive interface changes.
