How to Use Claude for WordPress Development: The Hana Skill Guide

WordPress runs a huge share of the web precisely because you do not have to be a developer to use it — right up until the moment you do. You need a snippet for functions.php, a child theme tweak, a custom post type, or a fix for the plugin conflict that just took the site down. Using Claude for WordPress development gives you that developer on call: a tool like Claude, ChatGPT, or any AI chat that writes the code, explains the fix, and keeps you from pasting something dangerous into a live site. It does not log into your dashboard — it gives you exactly what to do once you are there.

The snippet you need, explained

Half of WordPress customisation is a small piece of PHP in the right place. The skill writes the snippet — the hook, the filter, the function — and tells you where it goes and what it does, so you are not blindly pasting from a forum. Understanding the code is what stops the next problem.

Child themes and safe customisation

The classic disaster is editing a theme directly, then losing it all on the next update. The skill steers you to the right way — child themes, the customiser, the proper enqueue — so your changes survive updates. Doing it safely the first time is far cheaper than rebuilding.

Custom post types, fields, and templates

When the build outgrows pages and posts, the skill helps you set up custom post types, taxonomies, and the template files to display them — the structure behind a site that does more than blog. It explains the moving parts so you can maintain it later.

The plugin conflict that broke everything

The white screen of death after an update is a rite of passage. The skill helps you diagnose methodically — isolate the plugin, read the error, find the fix — instead of panic-deactivating everything. A calm, ordered debug is the difference between five minutes and a ruined afternoon.

Performance, security, and the basics done right

The skill helps with the housekeeping that keeps a WordPress site healthy — caching, image handling, the security basics, the settings people skip. For the search side of a WordPress site specifically, pair this with our WordPress SEO guide; for heavier front-end work, our frontend development guide goes further.

Why a skill beats a one-off prompt

A loaded skill knows your setup — your theme, your key plugins, your hosting quirks — so its code and fixes fit your site rather than a generic install. That context is what makes the advice safe to actually run.

The honest limit — back up first

The skill writes strong code from what you tell it, but it cannot see your live site, and any snippet can misbehave against a specific theme or plugin mix. The rule is non-negotiable: back up and test on staging before you touch production. Treat the skill as a sharp developer handing you code to review and test — not a reason to skip the safety net. Used that way, using Claude for WordPress development means you stop being stuck the moment WordPress asks for a line of code.
