Compound Engineering Plugin

Compound Engineering Plugin is an open-source plugin from Every that adds a set of skills to AI coding agents such as Claude Code, Cursor, and Codex. It organizes engineering work around a loop of brainstorming, planning, building, simplifying, reviewing, and capturing what was learned. The GitHub README describes 36 skills and support for 14 agent hosts, and it is maintained by Kieran Klaassen and Trevin Chow with community contributions.

What It Is

The plugin packages a workflow philosophy as installable agent skills. Its core idea is that each unit of engineering work should make later work easier rather than harder. The loop is /ce-brainstorm, /ce-plan, /ce-work, /ce-simplify-code, /ce-code-review, and /ce-compound. The final step writes learnings into docs/solutions/ so later brainstorming and planning can read them as grounding. The Every guide says the approach emerged from building Cora and that the plan and review steps should take most of an engineer's time.

How the Workflow Runs

Brainstorming produces a requirements-only plan, planning turns it into an implementation-ready plan, and work executes that plan. Code review is report-only and multi-agent, run against the plan before merge. Compounding captures the lesson as searchable markdown. The /lfg skill runs the pipeline hands-off, including code review, learning capture, and browser tests. It then commits, and when a git remote exists it pushes, opens a PR, and watches CI with a bounded repair loop. Other skills cover debugging (ce-debug), ideation (ce-ideate), PR feedback resolution, worktrees, browser testing, and setup. /ce-setup creates a repo config file and reports optional tool capabilities.

Install and Host Support

Installation is through each host's plugin mechanism, for example the plugin marketplace commands in Claude Code and Cursor. Codex, Kimi Code CLI, Cline, Grok Build CLI, Devin CLI, GitHub Copilot, Factory Droid, Qwen Code, OpenCode, Pi, oh-my-pi, and Antigravity CLI are also documented. Bun is only needed for repository development and converter maintenance.

Project Conventions

Artifact folders such as docs/solutions/ and docs/plans/ are defaults and can be relocated through a docs_root setting. The README also describes experimental Compound Packs, which are folders of rules that planning grounds in and review enforces. The project is MIT licensed, and the maintainers describe it as opinionated by design.
