AI skills and agents that make each unit of engineering work easier than the last.
## Philosophy
**Each unit of engineering work should make subsequent units easier -- not harder.**
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`
- 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
`/ce-strategy` is upstream of the loop -- it captures the product's target problem, approach, persona, metrics, and tracks as a short durable anchor at `STRATEGY.md`. Ideate, brainstorm, and plan read it as grounding when present, so strategy choices flow into feature conception, prioritization, and spec.
The core loop is: brainstorm the requirements, plan the implementation, work through the plan, review the result, compound the learning, then repeat with better context.
Use `/ce-ideate` before the loop when you want the agent to generate and critique bigger ideas before choosing one to brainstorm. It produces a ranked ideation artifact, not requirements, plans, or code.
| Skill | Purpose |
|-------|---------|
| `/ce-strategy` | Create or maintain `STRATEGY.md` -- the product's target problem, approach, persona, key metrics, and tracks. Read as grounding by ideate, brainstorm, and plan |
| `/ce-ideate` | Optional big-picture ideation: generate and critically evaluate grounded ideas, then route the strongest one into brainstorming |
| `/ce-brainstorm` | Interactive Q&A to think through a feature or problem and write a right-sized requirements doc before planning |
| `/ce-plan` | Turn feature ideas into detailed implementation plans |
| `/ce-work` | Execute plans with worktrees and task tracking |
| `/ce-debug` | Systematically reproduce failures, trace root cause, and implement fixes |
| `/ce-code-review` | Multi-agent code review before merging |
| `/ce-compound` | Document learnings to make future work easier |
| `/ce-product-pulse` | Generate a single-page, time-windowed pulse report on usage, performance, errors, and followups. Saves to `docs/pulse-reports/` |
`/ce-product-pulse` is the read-side companion -- a time-windowed report on what users actually experienced and how the product performed over a given window (24h, 7d, etc.), saved to `docs/pulse-reports/` so past pulses form a browseable timeline of user outcomes. The next strategy update and the next brainstorm get real signal to anchor to.
Each cycle compounds: brainstorms sharpen plans, plans inform future plans, reviews catch more issues, patterns get documented.
## Quick Example
A typical cycle starts by turning a rough idea into a requirements doc, then planning from that doc before handing execution to `/ce-work`:
/ce-brainstorm "make background job retries safer"
/ce-plan docs/brainstorms/background-job-retry-safety-requirements.md
/ce-work
/ce-code-review
/ce-compound
For a focused bug investigation:
/ce-debug "the checkout webhook sometimes creates duplicate invoices"
/ce-code-review
/ce-compound
## Getting Started
After installing, run `/ce-setup` in any project. It checks your environment, installs missing tools, and bootstraps project config.
The `compound-engineering` plugin currently ships 37 skills and 51 agents. See the [full component reference](plugins/compound-engineering/README.md) for the complete inventory.
## Install
### Claude Code
/plugin marketplace add EveryInc/compound-engineering-plugin
/plugin install compound-engineering
### Cursor
In Cursor Agent chat, install from the plugin marketplace:
/add-plugin compound-engineering
Or search for "compound engineering" in the plugin marketplace.
### Codex
Three steps: register the marketplace, install the agent set, then install the plugin through Codex's TUI.
1. **Register the marketplace with Codex:**
codex plugin marketplace add EveryInc/compound-engineering-plugin
2. **Install the Compound Engineering agents** (Codex's plugin spec does not register custom agents yet):
bunx @every-env/compound-plugin install compound-engineering --to codex
3. **Install the plugin through Codex's TUI:** launch `codex`, run `/plugins`, find the **Compound Engineering** marketplace, select the **compound-engineering** plugin, and choose **Install**. Restart Codex after install completes. Codex's CLI can register marketplaces, but it does not currently expose a plugin-install subcommand for plugins from an added marketplace -- the `/plugins` TUI install is required for CE skills.
All three steps are needed. The marketplace registration plus TUI install handles skills; the Bun step adds the review, research, and workflow agents that skills like `$ce-code-review`, `$ce-plan`, and `$ce-work` spawn in Codex. Without the agent step, delegating skills will report missing agents.
For a non-default Codex profile, run every Codex-related step against the same `CODEX_HOME`. This example installs CE into a `work` profile:
CODEX_HOME="$HOME/.codex/profiles/work" codex plugin marketplace add EveryInc/compound-engineering-plugin
CODEX_HOME="$HOME/.codex/profiles/work" bunx @every-env/compound-plugin install compound-engineering --to codex
CODEX_HOME="$HOME/.codex/profiles/work" codex
Inside Codex, run `/plugins`, select **Compound Engineering**, then install **compound-engineering**. The marketplace step only makes the plugin available; the TUI install is what activates the native CE skills for that profile.
For local development from this checkout, register the current worktree and use the local CLI:
CODEX_HOME="$HOME/.codex/profiles/work" codex plugin marketplace add "$PWD"
CODEX_HOME="$HOME/.codex/profiles/work" bun run src/index.ts install ./plugins/compound-engineering --to codex
CODEX_HOME="$HOME/.codex/profiles/work" codex
If you previously used the Bun-only Codex install, back up stale CE artifacts before switching:
bunx @every-env/compound-plugin cleanup --target codex
### 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
If you previously used the old Bun Copilot install, back up stale CE artifacts before switching to the native plugin:
bunx @every-env/compound-plugin cleanup --target copilot
### 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.
If you previously used the old Bun Droid install, back up stale CE artifacts before switching to the native plugin:
bunx @every-env/compound-plugin cleanup --target droid
### 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.
If you previously used the old Bun Qwen install, back up stale CE artifacts before switching to the native extension:
bunx @every-env/compound-plugin cleanup --target qwen
### OpenCode, Pi, Gemini, and Kiro
This repo includes a Bun/TypeScript installer that converts the Compound Engineering plugin to OpenCode, Pi, Gemini CLI, and Kiro CLI.
bunx @every-env/compound-plugin install compound-engineering --to opencode
bunx @every-env/compound-plugin install compound-engineering --to pi
bunx @every-env/compound-plugin install compound-engineering --to gemini
bunx @every-env/compound-plugin install compound-engineering --to kiro
**Pi prerequisites.** Pi does not ship a native subagent primitive, so the Pi install depends on [nicobailon/pi-subagents](https://github.com/nicobailon/pi-subagents) (required) and recommends [edlsh/pi-ask-user](https://github.com/edlsh/pi-ask-user) for richer blocking user questions:
pi install npm:pi-subagents # required — provides the `subagent` tool used by skills that dispatch parallel agents
pi install npm:pi-ask-user # recommended — provides the `ask_user` tool; skills fall back to numbered options in chat when it is missing
To auto-detect custom-install targets and install to all:
bunx @every-env/compound-plugin install compound-engineering --to all
The custom install targets run CE legacy cleanup during install. To run cleanup manually for a specific target:
bunx @every-env/compound-plugin cleanup --target codex
bunx @every-env/compound-plugin cleanup --target opencode
bunx @every-env/compound-plugin cleanup --target pi
bunx @every-env/compound-plugin cleanup --target gemini
bunx @every-env/compound-plugin cleanup --target kiro
bunx @every-env/compound-plugin cleanup --target copilot # old Bun installs only
bunx @every-env/compound-plugin cleanup --target droid # old Bun installs only
bunx @every-env/compound-plugin cleanup --target qwen # old Bun installs only
bunx @every-env/compound-plugin cleanup --target windsurf # deprecated legacy installs only
Cleanup moves known CE artifacts into a `compound-engineering/legacy-backup/` directory under the target root.
## Local Development
bun install
bun test
bun run release:validate
### From your local checkout
For active development -- edits to the plugin source are reflected immediately.
alias cce='claude --plugin-dir ~/Code/compound-engineering-plugin/plugins/compound-engineering'
Run `cce` instead of `claude` to test your changes. Your production install stays untouched.
**Codex and other targets** -- run the local CLI against your checkout:
# from the repo root
bun run src/index.ts install ./plugins/compound-engineering --to codex
# same pattern for other targets
bun run src/index.ts install ./plugins/compound-engineering --to opencode
### From a pushed branch
For testing someone else's branch or your own branch from a worktree, without switching checkouts. Uses `--branch` to clone the branch to a deterministic cache directory.
**Claude Code** -- use `plugin-path` to get the cached clone path:
# from the repo root
bun run src/index.ts plugin-path compound-engineering --branch feat/new-agents
# Output:
# claude --plugin-dir ~/.cache/compound-engineering/branches/compound-engineering-feat~new-agents/plugins/compound-engineering
The cache path is deterministic. Re-running updates the checkout to the latest commit on that branch.
**Codex, OpenCode, and other targets** -- pass `--branch` to `install`:
# from the repo root
bun run src/index.ts install compound-engineering --to codex --branch feat/new-agents
# works with any target
bun run src/index.ts install compound-engineering --to opencode --branch feat/new-agents
# combine with --also for multiple targets
bun run src/index.ts install compound-engineering --to codex --also opencode --branch feat/new-agents
Both features use the `COMPOUND_PLUGIN_GITHUB_SOURCE` env var to resolve the repository, defaulting to `https://github.com/EveryInc/compound-engineering-plugin`.
### Shell aliases
Add to `~/.zshrc` or `~/.bashrc`. All aliases use the local CLI so there is no dependency on npm publishing. `plugin-path` prints just the path to stdout, so it composes with `$()`.
CE_REPO=~/Code/compound-engineering-plugin
ce-cli() { bun run "$CE_REPO/src/index.ts" "$@"; }
# --- Local checkout (active development) ---
alias cce='claude --plugin-dir $CE_REPO/plugins/compound-engineering'
codex-ce() {
ce-cli install "$CE_REPO/plugins/compound-engineering" --to codex "$@"
}
# --- Pushed branch (testing PRs, worktree workflows) ---
ccb() {
claude --plugin-dir "$(ce-cli plugin-path compound-engineering --branch "$1")" "${@:2}"
}
codex-ceb() {
ce-cli install compound-engineering --to codex --branch "$1" "${@:2}"
}
Usage:
cce # local checkout with Claude Code
codex-ce # install local checkout to Codex
ccb feat/new-agents # test a pushed branch with Claude Code
ccb feat/new-agents --verbose # extra flags forwarded to claude
codex-ceb feat/new-agents # install a pushed branch to Codex
Codex installs keep generated plugin skills isolated under `~/.codex/skills/compound-engineering/` and do not write new files into `~/.agents`. The installer removes old CE-managed `.agents/skills` symlinks when it can prove they point back to CE's Codex-managed store, which prevents stale Codex installs from shadowing Copilot's native plugin install.
## Troubleshooting
### Codex skills work but review or research delegation fails
Run the agent install step:
bunx @every-env/compound-plugin install compound-engineering --to codex
Native Codex plugin install handles skills. The Bun step installs the custom agents those skills delegate to.
### Codex shows stale or duplicate CE skills
Back up old Bun-installed artifacts before switching to the native Codex plugin flow:
bunx @every-env/compound-plugin cleanup --target codex
## Limitations
Codex native plugin install currently handles skills, not custom agents. The documented Bun followup is required until Codex supports agents in its native plugin spec.
OpenCode, Pi, Gemini, and Kiro installs are converter-backed and may change as those target formats evolve.
Release versions are owned by release automation. Routine feature PRs should not hand-bump plugin or marketplace manifest versions.
## FAQ
### Do I need Bun for Claude Code?
No. Claude Code installs directly from the plugin marketplace. Bun is only needed for converter-backed targets, Codex's current agent followup, local development, and cleanup of old converted installs.
### Why does Codex need a separate Bun step?
Codex's native plugin flow installs skills from the Codex plugin manifest. It does not currently install the custom reviewer, researcher, and workflow agents that Compound Engineering skills delegate to. The Bun step fills that gap.
### Where do I see all available skills and agents?
Read the [Compound Engineering plugin README](plugins/compound-engineering/README.md). It lists the current skill and agent inventory.
### Where is release history?
GitHub Releases are the canonical release-notes surface. The root [`CHANGELOG.md`](CHANGELOG.md) points to that history.
