@summerive @ryuju0911 Can we divide this significantly huge commit into several ones? That should make it easy to develop, debug, and review.

[ryuju0911]

@summerive Let's divide the commits based on the directory.

[summerive]

@ryuju0911 OK. I committed files in go/tweets and go/posts. Should we make other issues for renaming tasks?

[summerive]

@ryuju0911 Excuse me. I didn't understand what you meant. I've just separated the last commit into several ones.

[ryuju0911]

@ryuji0123 @nayuta-ai Could you see if there is no problem in infra and swift directories?

[summerive]

I broke all the changes concerning the original issue. In this PR, I focused on making changes concerning the API entry point. Also, I changed the PR title according to the commit content.

[ryuji0123]

You can explicitly say tweet is replaced with post in both commit and PR titles.

[summerive]

I see. I will change them.
