# How to scope a custom WordPress plugin

Written by Red Gorilla Technology. Published 2026-10-12.

A plugin project goes well when the workflow is decided before the interface is decorated. These are the questions worth answering in the brief.

## Who uses it, and where

Name the person in wp-admin and the visitor, if there is one. A plugin that only staff use should not add public scripts. A plugin that prints something on the site should say which template is allowed to show it.

## What is stored

List the fields. Decide what is required, what is personal data, and how long it stays. Storage should live with the plugin, in its own table or a prefixed option, so it can be found, exported, and removed.

## What “done” means

- The admin labels match the words your team uses.
- A user without the right role cannot submit the action.
- Bad input is rejected with a message, not a white screen.
- Updating the plugin does not wipe the data.
- Uninstall behavior is written down.

## What to leave out

The first version should do the workflow you can describe in a paragraph. Reports, extra roles, and public widgets can follow once the main path has been used for real. A smaller plugin is easier to review and safer to update.
