Custom Post Type Generator

Name it, pick what it supports, copy the register_post_type() call. Everything else stays out of your way until you ask for it.

Naming

Singular name

Plural name

Post type key

Used in the database and in code. Max 20 characters, lowercase letters/numbers/dashes/underscores only.

Description optional

Behaviour

Public

Visible on the front end and in the admin. Off means an internal-only type.

Hierarchical (page-like)

Allows a parent to be set. Heavy on sites with thousands of entries.

Block editor (show_in_rest)

Required for Gutenberg and the REST API.

Archive page

Generates /slug/ listing every entry of this type.

Archive slug/book/

Supports

Editor panels and features this type gets.

Taxonomies

Attach at registration so query filters stay consistent.

Custom taxonomies still need their own register_taxonomy() call — the Taxonomy generator is next up.
