As part of our WordCamp US 2026 talk we built out the same plugin using this Starter pipeline and our Principal WP Pipeline using Opus 4.8 against the latest Frontier Sol 5.6 and Fable 5 models at xHigh.
the brief, both runs
Build an invite-only WordPress plugin for video-game collectors. Registered users search IGDB to add games to their library. Games can have one of four statuses (playing / finished / backlog / wishlist). They can curate a front-end library at
/my-library/, follow each other, and see an activity feed.

How to use the Pipeline
The Starter Pipeline is a very basic implementation of our Organizational AI Framework (without any real coordination). The pipeline contains 5 phases that guide you through the process of creating a piece of WordPress functionality.
You call it using this format:
/principal-wp-starter-pipeline “I want to build a weather block plugin. It should use the OpenWeatherMap API to show current conditions and a short forecast. Users should be able to search and pick a location in the editor and have the block show the weather for that spot. It should support a compact inline version, a card view, and an extended forecast table.”
The five build steps
01
Requirements
During the requirements phase the pipeline will ask you clarifying questions to understand what you’re trying to build. What’s included? What’s not? How do you want to handle any edge cases. This helps the pipeline understand your actual goal.
02
Research
For the Research phase the pipeline reads the codebase for relevant context, then updates the requirements with what it finds. It then asks follow up questions the research surfaced, flags any conflict with what it found and an earlier choice, and gives you a summary of the requirements along with a link to the full requirements.
03
Specs
This phase writes the spec and acceptance criteria for each requirement, breaking them down into individual tasks. It will ask you to review and approve this file before starting to code.
04
Code
During the code phase the pipeline implements the spec and writes tests.
05
Review
Four reviewers run sequentially (correctness, design, performance, security); each reviewer’s findings are fixed before the next one runs, and a final correctness and security re-review the fixes.
The Compounding phase
After the PR is built, three loops each make the next run better. None of them gates or blocks the PR:
Demo Recording
Records a short screen-walk video of the feature (skipped for backend-only work).
Advisor
Reads the built component through a list of specialist perspectives and writes non-blocking advice.md: things you might want to look at next.
Compound Learning
Proposes durable lessons for your project’s own CLAUDE.md in compound-learning.md; you paste the ones you agree with.

The starter pipeline was unveiled on Monday, August 17, 2026 at WordCamp US.
Get Started with the Starter Pipeline
It’s free and open source, licensed GPLv3, and on GitHub now. Clone it, read every agent’s instructions, and run it against your own project.
The repository has a card for each of the twelve agents, plus an interactive map of how a run moves through them.
