A Codex goal should say what finished means.
That sounds obvious, but it changes the whole session.
Write the finish line first
Do not start with a long background. Start with the result.
For example: publish ten English articles, keep the original images, and verify live URLs.
That tells Codex what success looks like.
Add the boundaries
A good goal also says what not to break.
For WordPress work, that might mean: do not remove images, do not change the Japanese source article, and check the live page after publishing.
Verify before calling it done
Completion is not just file creation.
For blog work, I want the live URL, status 200, and the expected image. For code work, I want tests or a clear reason tests were not run.
The point
A goal makes Codex less like a chat and more like a work loop.
