# Compound Engineering Plugin The Compound Engineering Plugin is a [[Claude Code]] marketplace plugin by [[Every.to]] that implements the Compound Engineering methodology — an AI-native development philosophy where each unit of work makes subsequent work easier, not harder. Licensed under MIT. ## The Methodology Compound Engineering inverts traditional development entropy. Instead of accumulating technical debt, each cycle feeds into the next: better plans inform future plans, reviews catch more issues, and documented patterns become reusable knowledge. ### The Core Loop **Plan → Work → Review → Compound → Repeat** - **Plan** (40% of time): Understand requirements, research the codebase, design solutions, validate approaches - **Work** (10% of time): Agent implements with isolation, validation, and progress tracking - **Review** (30% of time): Multiple specialized agents examine output in parallel, document patterns - **Compound** (20% of time): Capture solutions, make them discoverable, update the system, verify learnings 80% thinking (planning + review), 20% execution + system improvement. ### Key Principles - Each unit of work should make subsequent work easier - Encode taste into systems, not manual reviews - Teach the system, don't do the work yourself - Build safety nets, not gatekeeping - Make environments agent-native - Ship more value, type less code ## Plugin Features - **26 specialized agents** for specific jobs (security review, performance analysis, etc.) - **23 workflow commands** including the core loop plus utilities - **13 domain-specific skills** providing expertise on demand - **Multi-tool support**: Conversion utilities for Cursor, OpenCode, Codex, Gemini CLI, GitHub Copilot, Kiro CLI, and more ## The Compound Step The critical differentiator from regular AI-assisted development: - Document what worked and what didn't - Add metadata (YAML frontmatter) for discoverability - Update CLAUDE.md with new patterns and preferences - Create specialized agents when warranted - Verify the system would catch similar issues next time ## The 50/50 Rule - 50% engineering time shipping features - 50% improving the system (documentation, agents, test generators, review systems) ## References - GitHub: https://github.com/EveryInc/compound-engineering-plugin - Guide: https://every.to/guides/compound-engineering ## Related - [[Claude Code]] - [[Every.to]] - [[AI Agents]] - [[Software Development]]
