What it is
Compound Engineering is a plugin of 36 skills for AI coding agents. It guides work through a loop of brainstorming, planning, building, reviewing, and recording what was learned, so later changes can read that knowledge. According to the README, it runs on 14 agent hosts, including Claude Code, Cursor, and Codex.
- Brainstorm a feature with an interactive Q&A that produces a requirements-only plan using /ce-brainstorm
- Turn a requirements plan into an implementation plan with /ce-plan
- Run a report-only multi-agent review against the plan before merging with /ce-code-review
- Record a learning into docs/solutions/ with /ce-compound so the next session can read it
Great for
- Developers already using Claude Code, Cursor, or Codex who want structured planning and review steps
- Teams that want engineering lessons written to docs/solutions/ so future work can build on them
- People who prefer a plan-then-review workflow over ad hoc prompting
Not ideal for
- People who do not use any supported AI coding agent, since the skills run inside those hosts
- Users looking for a standalone application with its own interface, because the README describes it as a plugin
- Teams that need a fully documented, stable interface, since the latest release is v3.33.2 and the README does not describe stability guarantees
How to get it
- 1
See the README
You'll need: A supported AI coding agent host such as Claude Code, Cursor, or Codex
Claude Code: add marketplace (run inside Claude Code)
/plugin marketplace add EveryInc/compound-engineering-pluginClaude Code: install plugin (run inside Claude Code)
/plugin install compound-engineeringCodex CLI: register marketplace
codex plugin marketplace add EveryInc/compound-engineering-pluginCodex CLI: install plugin
codex plugin add compound-engineering@compound-engineering-plugin - 2
Run it
- Install the plugin in your agent host using the steps for that host in the README
- Restart the host if the README instructs it after install
- Run /ce-setup in any project to check optional tool capabilities and create the config file
- Start with /ce-brainstorm to think through a feature or problem
- 3
Get the most out of it
- Use /ce-compound after finishing work so later /ce-brainstorm and /ce-plan runs can read the captured learning
- Run /ce-code-review before merging; the README says it is report-only and local apply is explicit
- Set the docs_root setting if your docs/ folder holds tracked content, as described in the configuration guide
- Explore Compound Packs to share team or org rules that planning and review can cite
Downloads
Strengths
- Covers the full cycle from brainstorming through review and knowledge capture, per the README's described loop
- Supports many agent hosts, with install steps documented for Claude Code, Cursor, and Codex
- Released under the MIT license with a visible build status badge and active maintainers named in the README
Trade-offs
- Install steps differ by host, and the README notes that updating requires refreshing the marketplace first
- The README is truncated, so details of configuration and some commands are not fully visible here
- Outputs depend on the underlying AI model and host, which this analysis cannot verify
