Most developers using AI coding tools hit the same ceiling eventually. The agent writes code, you accept or reject it, and next time it starts from scratch again. There's no memory of what worked, no accumulated judgment about your codebase, no improvement from one session to the next. You're getting faster, but the tool isn't getting better at helping you specifically.
Compound Engineering is a plugin that tries to fix that. Built by Every.to and available for Claude Code, Cursor, Codex, GitHub Copilot, and a growing list of other tools, it introduces a structured workflow designed around a simple principle: each unit of engineering work should make the next one easier.
The Core Idea
Traditional development accumulates technical debt. Features add complexity, bug fixes leave behind knowledge no one wrote down, and the codebase slowly becomes harder to change.
The Compound Engineering philosophy inverts the ratio: 80% of the effort goes into planning and review, 20% into execution. The thinking is that a sharp plan produces a smaller, cleaner implementation. A good code review catches a pattern, not just a specific bug. A documented learning means the agent doesn't have to rediscover the same constraint next week.
