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 the arrow next to Create, then select Add marketplace.

3. Enter:

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

4. Click Add marketplace.

5. Search for Compound Engineering, install compound-engineering-plugin, 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.

Invocation syntax: this README uses /skill-name examples for slash-skill hosts. In Codex, invoke installed skills with $skill-name (for example, $ce-plan and $lfg); /goal remains a Codex built-in command.

Traditional development accumulates technical debt. Every feature adds complexity. Every bug fix leaves behind a little more local knowledge that someone has to rediscover later. The codebase gets larger, the context gets harder to hold, and the next change becomes slower.

Compound engineering inverts this. 80% is in planning and review, 20% is in execution:

• Plan thoroughly before writing code with /ce-brainstorm and /ce-plan using one readiness-based plan artifact
• Review to catch issues and calibrate judgment with /ce-code-review and /ce-doc-review
• Codify knowledge so it is reusable with /ce-compound
• Keep quality high so future changes are easy

The point is not ceremony. The point is leverage. A good brainstorm makes the plan sharper. A good plan makes execution smaller. A good review catches the pattern, not just the bug. A good compound note means the next agent does not have to learn the same lesson from scratch.

Workflow

The core loop is six steps: brainstorm the requirements, plan the implementation, work through the plan, simplify what you wrote, review the result, then compound the learning -- and repeat with better context.

Each cycle compounds: /ce-compound writes learnings that the next /ce-brainstorm and /ce-plan read as grounding -- brainstorms sharpen plans, plans inform future plans, reviews catch more issues, patterns get documented. That return arrow is the whole point.

Artifact folders like docs/solutions/ and docs/plans/ are the defaults. A project whose docs/ is tracked content can relocate every CE artifact folder under one repo-relative root via the docs_root setting -- see configuration.

Additional skills

These sit around the loop or get reached for on demand -- not every cycle needs them.

For the full catalog and how each skill chains together, see docs/skills. The complete inventory is below.

Quick Example

Finding a direction -- when you don't have a specific idea yet, ideate first, then carry the strongest survivor into the loop:

/ce-ideate new drawing tools
/ce-ideate surprise me
/ce-ideate open issues     # ground ideas in your tracker's open issues (GitHub, Linear, Jira)

/ce-ideate does the homework first (codebase, past learnings, prior art on the web, optionally your issue tracker), then hands you a ranked set of grounded candidates to take into /ce-brainstorm.

Standard feature loop -- turn a rough idea into shipped, reviewed code:

/ce-brainstorm make background job retries safer
/ce-plan
/ce-work
/ce-simplify-code
/ce-code-review
/ce-compound

Simplifying code -- use it after fresh implementation work, or point it at code that keeps slowing changes down:

/ce-simplify-code
/ce-simplify-code simplify the code in my most-churned file

The first pass tightens recent branch changes before review. The targeted pass is useful when one file keeps absorbing unrelated fixes, follow-ups, or merge conflicts.

Debugging a bug -- when you start from broken behavior instead of a feature:

/ce-debug the checkout webhook sometimes creates duplicate invoices
/ce-code-review
/ce-compound

Autonomous -- hand off a feature and let the agent run the whole pipeline:

/ce-brainstorm describe the feature
/lfg

/lfg runs the loop hands-off: it plans, works through the plan, simplifies, runs code review and applies the fixes, runs browser tests, commits, pushes, opens a PR, then watches CI and repairs failures until it's green. Start it after /ce-brainstorm so it plans against real requirements rather than a one-line prompt. It's the autopilot version of the standard loop -- neat when you want to step away and come back to an open, green PR. When an eligible multi-area plan still has unplanned work, lfg also recommends and justifies the next separately planned area; only if you accept does it create a /ce-handoff for a fresh session and separate plan.

Getting Started

After installing, run /ce-setup in any project. It checks repo-local config, reports optional tool capabilities, and helps keep machine-local CE settings safely gitignored.

The compound-engineering plugin currently ships 32 skills and 0 standalone agents. Specialist review, research, and workflow behavior lives inside the owning skills as skill-local prompt assets.

More Install Options

Claude Code, Cursor, and Codex are at the top. Everything here is equally supported.

Kimi Code CLI

Kimi Code CLI can install Compound Engineering directly from this repository because the repo ships a native .kimi-plugin/plugin.json manifest:

/plugins install https://github.com/EveryInc/compound-engineering-plugin

You can also browse it through Kimi's custom marketplace flow:

/plugins marketplace https://raw.githubusercontent.com/EveryInc/compound-engineering-plugin/main/.kimi-plugin/marketplace.json

After installing or updating, run /reload or start a new Kimi session so the plugin skills are loaded.

Cline

Cline loads CE skills from on-demand SKILL.md directories. Enable Settings -> Features -> Enable Skills in the Cline extension, then link this repository's skills globally or per project:

git clone https://github.com/EveryInc/compound-engineering-plugin
./compound-engineering-plugin/.cline/scripts/install-skills.sh --global

Per-project install from a checkout:

./compound-engineering-plugin/.cline/scripts/install-skills.sh --project

Start a new Cline task after installing or updating skills. See .cline/INSTALL.md for pinning, local development, and uninstall steps.

Grok Build CLI (grok)

xAI's Grok Build CLI (grok) installs Compound Engineering directly from this repository — the repo root is a valid Grok plugin (grok reads the existing Claude-compatible manifests, and the repo also ships a native .grok-plugin/plugin.json):

grok plugin install EveryInc/compound-engineering-plugin

This tracks the repository; run grok plugin update to pull the latest. To browse it as a marketplace source instead, the repo ships a native .grok-plugin/marketplace.json:

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

Both paths track the repository directly (no commit pin), so no Bun install step is needed. Add --trust to skip the install confirmation. grok stores config under ~/.grok; start a new session after installing so the skills load.

Compound Engineering is also being submitted to the official xAI plugin marketplace; see docs/grok-marketplace-submission.md for the maintainer runbook.

Devin CLI

Devin CLI can install Compound Engineering directly from GitHub because the repo ships a native .devin-plugin/plugin.json manifest:

devin plugins install EveryInc/compound-engineering-plugin

Verify the install and inspect the skills:

devin plugins list
devin plugins info compound-engineering

Update to the latest version with devin plugins update compound-engineering. Plugins load at session start, so start a new Devin session after installing or updating for the skills to appear (as /compound-engineering:<skill> slash commands).

A few skills declare Claude-style allowed-tools names that Devin does not map (for example Bash); those skills still work, but some of their actions ask for permission instead of running auto-approved. See docs/specs/devin.md for details.

GitHub Copilot

For VS Code Copilot Agent Plugins:

1. Run Chat: Install Plugin from Source from the VS Code command palette
2. Use EveryInc/compound-engineering-plugin for the repo
3. Select compound-engineering when VS Code shows the plugins in this repository

For Copilot CLI, use:

Inside Copilot CLI:

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

From a shell with the copilot binary:

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

Copilot CLI reads the existing Claude-compatible plugin manifests, so no separate Bun install step is needed.

Factory Droid

From a shell with the droid binary:

droid plugin marketplace add https://github.com/EveryInc/compound-engineering-plugin
droid plugin install compound-engineering@compound-engineering-plugin

Droid uses plugin@marketplace plugin IDs; here compound-engineering is the plugin and compound-engineering-plugin is the marketplace name. Droid installs the existing Claude Code-compatible plugin and translates the format automatically, so no Bun install step is needed.

Qwen Code

qwen extensions install EveryInc/compound-engineering-plugin:compound-engineering

Qwen Code installs Claude Code-compatible plugins directly from GitHub and converts the plugin format during install, so no Bun install step is needed.

OpenCode

Add Compound Engineering to the plugin array in your global or project opencode.json:

{
  "plugin": ["compound-engineering@git+https://github.com/EveryInc/compound-engineering-plugin.git"]
}

Restart OpenCode after changing the config. The OpenCode plugin registers the Compound Engineering skills directory directly; no Bun installer or generated skill copy is required. See .opencode/INSTALL.md for pinning examples.

Pi

Install Compound Engineering as a Pi package from this repository:

pi install git:github.com/EveryInc/compound-engineering-plugin

Required companion for CE workflows that dispatch reviewer, research, or implementation subagents:

pi install npm:pi-subagents

Recommended companion for richer blocking questions:

pi install npm:pi-ask-user

Antigravity CLI (agy)

Google has replaced the consumer Gemini CLI with Antigravity CLI (agy), which still runs on Gemini models. Install Compound Engineering directly from GitHub — no clone step required:

agy plugin install https://github.com/EveryInc/compound-engineering-plugin

Verify with agy plugin list. The repository root is the plugin package (plugin.json plus skills/).

For a local checkout or pinned release:

git clone https://github.com/EveryInc/compound-engineering-plugin
agy plugin install ./compound-engineering-plugin

The bundled .agy/ directory remains a compatibility entry point (agy plugin install ./compound-engineering-plugin/.agy). agy also loads GEMINI.md workspace context from the checkout.

See .agy/INSTALL.md for pinning, local development, uninstall, and legacy Gemini import.

Existing Installs

Compound Engineering moved to a root-native, skills-only layout. An existing marketplace install keeps a cached marketplace snapshot that still points at the old plugins/compound-engineering path, so updating the plugin on its own reads that stale snapshot and leaves you on the previous version. Refresh the cached marketplace first, then update the plugin — order matters.

Claude Code

/plugin marketplace update compound-engineering-plugin
/plugin update compound-engineering

Codex CLI

codex plugin marketplace upgrade compound-engineering-plugin
codex plugin add compound-engineering@compound-engineering-plugin

There is no codex plugin update; re-running add reinstalls from the refreshed snapshot. For a non-default profile, run both commands against the same CODEX_HOME.

Codex App

Refresh the marketplace from the Plugins panel (remove and re-add the EveryInc/compound-engineering-plugin marketplace if there is no refresh control), then reinstall compound-engineering and restart Codex.

If you configured a host with a direct path or sparse path under plugins/compound-engineering, edit or reinstall that source so it points at the repository root with no sparse path.

If a previous Bun-installed copy is still shadowing native plugin skills, run the current cleanup command from a checkout of this repository:

git clone https://github.com/EveryInc/compound-engineering-plugin.git /tmp/compound-engineering-plugin-cleanup
cd /tmp/compound-engineering-plugin-cleanup
bun install
bun run cleanup --target all

Local Development

bun install
bun test
bun run release:validate

From your local checkout

For active development, load this checkout directly in the harness you want to test.

Claude Code

claude --plugin-dir "$PWD"

Cursor Agent CLI

cursor-agent --plugin-dir "$PWD"

Codex

For the normal production-like plugin installation, use the Codex App or Codex CLI instructions above. The workflow below is only for contributors who need Codex to load unreleased files from an exact checkout or linked worktree.

bun run codex:dev -- local

bun run codex:dev -- status
bun run codex:dev -- refresh
bun run codex:dev -- remote
bun run codex:dev -- remove

Kimi Code CLI

Inside Kimi Code CLI:

/plugins install /path/to/compound-engineering-plugin

To test the local marketplace catalog instead, pass the catalog path:

/plugins marketplace /path/to/compound-engineering-plugin/.kimi-plugin/marketplace.json

Cline

/path/to/compound-engineering-plugin/.cline/scripts/install-skills.sh --global

Enable Settings -> Features -> Enable Skills in the Cline extension, then start a new task.

Devin CLI

devin plugins install /path/to/compound-engineering-plugin

Local installs are linked to the checkout rather than copied, so skill edits apply on the next Devin session without reinstalling.

OpenCode

{
  "plugin": ["/path/to/compound-engineering-plugin"]
}

Restart OpenCode after changing opencode.json.

Pi

pi -e "$PWD"

Antigravity CLI (agy)

agy plugin install "$PWD"
agy plugin validate "$PWD"

Or install the bundled .agy/ entry point:

agy plugin install "$PWD/.agy"

See .agy/INSTALL.md for remote install and pinning examples.

Limitations

OpenCode and Pi use native package/plugin loading from this repository. The Bun CLI remains for repository development and converter maintenance, not normal installation.

Release versions are owned by release automation. Routine feature PRs should not hand-bump plugin or marketplace manifest versions.

FAQ

Do I need Bun to install Compound Engineering?

No. Bun is only needed for repo development tasks and converter maintenance.

Where do I see all available skills?

The skill inventory is in this README, and the deeper skill catalog is in docs/skills/README.md. Each skill's authoritative runtime spec lives in skills/<skill>/SKILL.md.

Where is release history?

GitHub Releases are the canonical release-notes surface. The root CHANGELOG.md points to that history.

Contributing

Contributions are welcome. Issues, bug reports, and pull requests all help make this better, and we genuinely appreciate them — bug reports especially.

A note on what to expect: Compound Engineering is opinionated by design. It's maintained by @kieranklaassen and @tmchow, and its direction reflects a specific point of view about how AI-assisted engineering should work. So while we welcome help, we can't promise to accept every change — some proposals won't fit that vision even when they're good ideas on their own.

Open an issue or send a PR, and we'll fold in what moves the plugin in the right direction. We just want to be upfront that not everything will land.
