everyinc/compound-engineering-plugin

Compound Engineering is an official plugin for AI coding tools like Claude Code, Cursor, and Codex that helps developers work smarter over time. The core idea is that each unit of engineering work should make the next one easier, not harder. Traditional software development tends to accumulate technical debt, where every new feature adds complexity and slows things down. This plugin inverts that pattern by emphasizing planning and review over raw execution. Eighty percent of the effort goes into thinking before and after writing code, and only twenty percent into the actual coding. The plugin provides a set of slash commands that guide teams through a repeating cycle: brainstorm requirements, turn them into a detailed implementation plan, execute the plan, review the result, and then document what was learned so future work benefits. Key commands include brainstorm for thinking through a feature, plan for turning ideas into step-by-step guides, debug for systematically finding and fixing bugs, code review for multi-agent review before merging, and compound for writing down lessons learned. There is also a strategy command that creates a durable anchor file capturing the product goals, so every brainstorm and plan stays grounded in the bigger picture. The plugin ships with 37 skills and 51 agents and installs in a few steps inside any supported AI coding environment. It is built with TypeScript and published to the npm registry.
