Compound Engineering

AI skills that make each unit of engineering work easier than the last.

Install

Claude Code

/plugin marketplace add EveryInc/compound-engineering-plugin
/plugin install compound-engineering

Already have Compound Engineering installed? Compound Engineering moved to a root-native layout. You must refresh the marketplace before updating — see Existing Installs. Running /plugin update alone keeps you on the old version.

Cursor

In Cursor Agent chat, install from the plugin marketplace:

/add-plugin compound-engineering

Or search for "compound engineering" in the plugin marketplace.

Codex App

Compound Engineering is not listed in Codex's built-in plugin marketplace yet. Add it as a custom marketplace:

1. In the Codex app, open Plugins from the sidebar.

2. Click Add / Add plugin marketplace.

3. Enter:

   Field	Value
   Source	EveryInc/compound-engineering-plugin
   Git ref	main
   Sparse paths	leave blank

4. Click Add marketplace.

5. Select Compound Engineering, install compound-engineering, then restart Codex.

The Codex app install is self-contained for Compound Engineering. Specialist reviewer and research behavior lives inside the skills as local prompt assets; no separate custom-agent install step is required.

Codex CLI

Register the marketplace, then install the plugin.

1. Register the marketplace with Codex:

   codex plugin marketplace add EveryInc/compound-engineering-plugin
   

2. Install the plugin:

   codex plugin add compound-engineering@compound-engineering-plugin
   

   You can also launch codex, run /plugins, find the Compound Engineering marketplace, select the compound-engineering plugin, and choose Install. Restart Codex after install completes.

The native Codex plugin install is self-contained for Compound Engineering. Specialist reviewer and research behavior lives inside the skills as local prompt assets; no separate custom-agent install step is required.

For a non-default Codex profile, run every Codex-related step against the same CODEX_HOME. This example installs CE into a work profile:

CODEX_HOME="$HOME/.codex/profiles/work" codex plugin marketplace add EveryInc/compound-engineering-plugin
CODEX_HOME="$HOME/.codex/profiles/work" codex plugin add compound-engineering@compound-engineering-plugin

The marketplace step only makes the plugin available; the plugin install is what activates the native CE skills for that profile.

Remove the legacy Codex tool map (pre-native installs)

If you previously installed Compound Engineering with the Bun convert / install --to codex CLI (before native Codex plugin support), that path may have inserted a managed block into your global Codex instructions file:

<!-- BEGIN COMPOUND CODEX TOOL MAP --> … <!-- END COMPOUND CODEX TOOL MAP -->

in $CODEX_HOME/AGENTS.md (default ~/.codex/AGENTS.md). That Claude-compat tool map is obsolete — CE skills name Codex tools inline — and one of its lines incorrectly told Codex to collapse subagent dispatch onto the main thread. Native plugin install does not add this block.

Paste this into Codex (or any agent with access to your home directory) to remove it:

Remove the obsolete Compound Engineering Codex tool-map block from my Codex home AGENTS.md.

1. Check `$CODEX_HOME/AGENTS.md` if CODEX_HOME is set, otherwise `~/.codex/AGENTS.md`. If I use Codex profiles, also check `~/.codex/profiles/*/AGENTS.md`.
2. Look for the exact sentinels `<!-- BEGIN COMPOUND CODEX TOOL MAP -->` and `<!-- END COMPOUND CODEX TOOL MAP -->`.
3. If both are present, delete only the span from the BEGIN line through the END line (inclusive), leaving any other user content untouched. Do not edit project/repo AGENTS.md unless those exact sentinels are present there.
4. If the file is empty after the removal, delete the file.
5. Show a short before/after summary of what you changed (or say the block was already absent). Do not add a replacement tool map.

Re-running the Bun convert/install CLI for Codex also strips the block if it is still present; it no longer inserts it.

Another editor or CLI? Kimi Code CLI, Cline, Grok Build CLI, Devin CLI, GitHub Copilot, Factory Droid, Qwen Code, OpenCode, Pi, and Antigravity CLI are all supported — see More install options.

Philosophy

Each unit of engineering work should make subsequent units easier -- not harder.
