Compounding Engineering Plugin

AI-powered development tools that get smarter with every use. Make each unit of engineering work easier than the last.

Getting Started

After installing, run /ce-setup in any project. It diagnoses your environment, installs missing tools, and bootstraps project config in one interactive flow.

Skills

Core Workflow

The primary entry points for engineering work are skills invoked with slash syntax:

Skill	Description
/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	Create structured plans for any multi-step task -- software features, research workflows, events, study plans -- with automatic confidence checking
/ce-code-review	Structured code review with tiered persona agents, confidence gating, and dedup pipeline
/ce-work	Execute work items systematically
/ce-debug	Systematically find root causes and fix bugs -- traces causal chains, forms testable hypotheses, and implements test-first fixes
/ce-compound	Document solved problems to compound team knowledge
/ce-compound-refresh	Refresh stale or drifting learnings and decide whether to keep, update, replace, or archive them
/ce-optimize	Run iterative optimization loops with parallel experiments, measurement gates, and LLM-as-judge quality scoring

For /ce-optimize, see skills/ce-optimize/README.md for usage guidance, example specs, and links to the schema and workflow docs.

Research & Context

Skill	Description
/ce-sessions	Ask questions about session history across Claude Code, Codex, and Cursor
/ce-slack-research	Search Slack for interpreted organizational context -- decisions, constraints, and discussion arcs

Git Workflow

Skill	Description
ce-pr-description	Write or regenerate a value-first PR title and body from the current branch or a specified PR; used directly or by other skills
ce-clean-gone-branches	Clean up local branches whose remote tracking branch is gone
ce-commit	Create a git commit with a value-communicating message
ce-commit-push-pr	Commit, push, and open a PR with an adaptive description; also update an existing PR description (delegates title/body generation to ce-pr-description)
ce-worktree	Manage Git worktrees for parallel development

Workflow Utilities

Skill	Description
/ce-demo-reel	Capture a visual demo reel (GIF demos, terminal recordings, screenshots) for PRs with project-type-aware tier selection
/ce-report-bug	Report a bug in the compound-engineering plugin
/ce-resolve-pr-feedback	Resolve PR review feedback in parallel
/ce-test-browser	Run browser tests on PR-affected pages
/ce-test-xcode	Build and test iOS apps on simulator using XcodeBuildMCP
/ce-setup	Diagnose environment, install missing tools, and bootstrap project config
/ce-update	Check compound-engineering plugin version and fix stale cache (Claude Code only)
/ce-release-notes	Summarize recent compound-engineering plugin releases, or answer a question about a past release with a version citation

Development Frameworks

Skill	Description
ce-agent-native-architecture	Build AI agents using prompt-native architecture
ce-dhh-rails-style	Write Ruby/Rails code in DHH's 37signals style

Review & Quality

Skill	Description

Automation & Tools

Skill	Description
ce-gemini-imagegen	Generate and edit images using Google's Gemini API

Beta / Experimental

Skill	Description
/ce-polish-beta	Human-in-the-loop polish phase after /ce-code-review — verifies review + CI, starts a dev server from .claude/launch.json, generates a testable checklist, and dispatches polish sub-agents for fixes. Emits stacked-PR seeds for oversized work
/lfg	Full autonomous engineering workflow
