AI-Powered Development Tools That Get Smarter With Every Use
Make each unit of engineering work easier than the last. 24 specialized agents, 16 powerful commands, 11 intelligent skills, and 2 MCP servers for code review, research, design, and workflow automation.
The Compounding Engineering Philosophy
Every unit of engineering work should make subsequent units of work easier—not harder.
"Most engineering creates linear value: you build a feature, it works, done. Compounding engineering creates exponential value: each solved problem teaches the system, each pattern becomes reusable, each review strengthens future reviews."
Plan
Understand before you build
Before writing a single line of code, gather context. Research agents explore
documentation, analyze git history, and find best practices. The /workflows:plan
command orchestrates 3 research agents in parallel to create comprehensive implementation plans.
Delegate
Leverage specialized expertise
Each agent brings deep domain knowledge. The kieran-rails-reviewer knows Rails
conventions like an expert. The security-sentinel catches OWASP vulnerabilities.
The /workflows:work command executes plans while maintaining quality gates.
Assess
Multiple perspectives, comprehensive coverage
The /workflows:review command launches 12+ review agents in parallel: security,
performance, architecture, data integrity, patterns, and more. Findings are categorized by
severity (P1/P2/P3) and stored as actionable todo files.
Codify
Turn solutions into knowledge
Every solved problem should teach the system. The /workflows:codify command
captures solutions as searchable documentation. The feedback-codifier agent
extracts patterns from code reviews to improve future reviews.

What is Compounding Engineering?
Compounding Engineering is a philosophy that every unit of engineering work should make subsequent units easier—not harder. This plugin embodies that philosophy with tools that learn from patterns, automate repetitive tasks, and build institutional knowledge.
How do agents differ from skills?
Agents are specialized personas that can be invoked to perform specific tasks
(e.g., code review, research). They're called with claude agent [name].
Skills provide domain expertise that Claude Code can use on-demand. They include
reference materials, templates, and workflows. They're invoked with skill: [name].
Why aren't MCP servers loading automatically?
This is a known issue. As a workaround, manually add the MCP servers to your
.claude/settings.json file. See the README for the exact configuration.
Can I use this with languages other than Ruby/Rails?
Yes! While many agents are specialized for Rails, we also have Python and TypeScript reviewers. The workflow commands, research agents, and skills like gemini-imagegen work with any language.
How do I create my own agents or skills?
Use the /create-agent-skill command or the create-agent-skills skill
for expert guidance. The skill includes templates, best practices, and validation workflows.
