One practical Codex use case is not flashy at all: comparing package versions between production and staging.
For Shopware projects, Composer dependencies matter. Before deployment, I often need to check Shopware core, plugins, and important packages across branches or environments. This used to mean switching branches, reading composer.json and composer.lock, spotting version differences, and making sure nothing important drifted.
With Codex, this kind of check can be done quickly and safely without exposing business logic. It can compare branches, identify exact version differences, update only what matters, and help validate the result.
This is the kind of AI workflow I like most: less time spent on repetitive checks, more confidence before deployment, and better focus on the decisions that actually need developer judgment.
