README

Principal WP — Claude Code marketplace

Public Claude Code tools from [Principal WP](https://principalwp.com), shipped as a single plugin: **principalwp-toolkit**.

Install

/plugin marketplace add principalwp/principal-claude-marketplace
/plugin install principalwp-toolkit@principalwp

After you install, restart Claude Code.

Updating

We recommend enabling auto updates. To do this, run `/plugin`, open the **Marketplaces** tab, select `principalwp`, and choose **Enable auto-update**, or ask Claude to enable auto-updates for the principalwp-toolkit.

To manually update, run the command below in the terminal, then restart Claude Code (as of August 2026, `/reload-plugins` doesn't reload marketplace plugins):

claude plugin update principalwp-toolkit@principalwp

What's in the PrincipalWP toolkit

WordPress Starter Pipeline

**[How the Starter Pipeline works →](https://principalwp.github.io/principal-claude-marketplace/principal-wp-starter-pipeline.html)** is a visual walkthrough of the phases and checkpoints.

Build or change a WordPress plugin or theme through a pipeline inside Claude Code. The pipeline runs checkpointed agent phases (requirements, research, spec, code, review) and opens a pull request that's been reviewed and tested. It has three human checkpoints and a closeout that improves your next run. Run it with `/principal-wp-starter-pipeline ""` from a component repo. The first run in a project does a one-time setup (E2E test stack, WordPress Agent Skills).

**Customizing the pipeline.** The pipeline reads an optional per-machine overrides file, `~/.claude/principal-wp-starter-pipeline-overrides.md`, at the start of every run and applies each `## ` section to the matching agent. Its Feedback Loop proposes additions to that file, so your customizations survive plugin updates without ever editing the shipped agents.
