What it does
Codex is OpenAI's coding product for working with repositories and engineering tasks. It helps interpret project context, make reviewable changes and run available checks, so the useful unit of work is a scoped task with a diff and evidence rather than an isolated generated snippet.
Start with a small task in a version-controlled project and define how the result will be checked. Inspect the diff, dependencies and test output before adopting a change; a runnable prototype still needs engineering review.
