# 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 |
