Compounding Engineering for Claude Code (github.com)

Every.to has published an official “Every marketplace” plugin for Claude that bundles a Compounding Engineering Philosophy toolkit — installable by running Claude and adding the marketplace (/plugin marketplace add https://github.com/EveryInc/every-marketplace) then installing /plugin install compounding-engineering. The package exposes AI-powered development agents, commands and five curated workflows designed to get smarter with every use: multi-expert code review, automated testing & bug reproduction, PR management with parallel comment resolution, continuous documentation generation and maintenance, and security/performance/architecture analysis. For the AI/ML community this formalizes a feedback-loop approach to engineering where each completed unit of work reduces friction for the next (Plan → Delegate → Assess → Codify). Technically this means integrated agents for task delegation, automated assessment and test reproduction, and persistent codified learnings that can feed downstream workflows and CI/CD — enabling scalable review, faster triage, and reproducible fixes. The compounding nature promises improved agent behavior over time but also raises operational considerations: integration with existing pipelines, quality gating, and human-in-the-loop oversight for security and correctness. Overall, it’s a practical step toward agent-driven software engineering that emphasizes repeatable, self-improving workflows.
