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 three 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 or more 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 with YAML frontmatter for fast lookup.

Frequently Asked Questions

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.
