Your Code Reviews Just Got 12 Expert Opinions. In 30 Seconds.
Here's what happened when we shipped yesterday: security audit, performance analysis, architectural review, pattern detection, and eight more specialized checks—all running in parallel. No meetings. No waiting. Just answers. That's compounding engineering: 24 specialized agents, 19 workflow commands, and 11 skills that make today's work easier than yesterday's.
Why Your Third Code Review Should Be Easier Than Your First
Think about the last time you fixed a Rails N+1 query. You found it. You fixed it. Then next month, different developer, same bug, same investigation. That's linear engineering—you solved it, but the solution evaporated.
"Most engineering work is amnesia. You solve a problem on Tuesday, forget the solution by Friday, and re-solve it next quarter. Compounding engineering is different: each solved problem teaches the system. The security review you run today makes tomorrow's review smarter. The pattern you codify this sprint prevents bugs in the next three."
Plan
Stop starting over from scratch
You know that moment when you open a ticket and think "how did we solve this last time?" The framework-docs-researcher already knows. The git-history-analyzer remembers what worked in March. Run /plan and three research agents work in parallel—one reading docs, one analyzing your repo's history, one finding community patterns. In 60 seconds, you have a plan built on institutional memory instead of starting cold.
Delegate
Work with experts who never forget
The security-sentinel has checked 10,000 PRs for SQL injection. The kieran-rails-reviewer never approves a controller with business logic. They don't get tired, don't skip Friday afternoon reviews, don't forget the conventions you agreed on in March. Run /work and watch your plan execute with quality gates that actually enforce your standards—every single time.
Assess
Get twelve opinions without twelve meetings
Type /review PR#123 and go get coffee. When you come back, you'll have a security audit (did you sanitize that user input?), performance analysis (N+1 spotted on line 47), architecture review (this breaks the pattern from v2.3), data integrity check (that migration will fail in production), and eight more specialized reviews. All running in parallel. All categorized by severity. All stored as actionable P1/P2/P3 todos you can knock out in order.
Compound
Make sure you never solve the same bug twice
Remember that CORS issue you debugged for three hours last month? Neither do I. That's the problem. Run /compound right after you fix something and it captures the solution as searchable documentation with YAML frontmatter. Next time someone hits the same issue, they grep for "CORS production" and find your answer in five seconds instead of re-debugging for three hours. That's how you compound.
24 Specialized Agents
Think of them as coworkers who never quit. The security-sentinel has seen every SQL injection variant. The kieran-rails-reviewer enforces conventions with zero compromise. The performance-oracle spots N+1 queries while you're still reading the PR. Run them solo or launch twelve in parallel—your choice.

Frequently Asked Questions
What is Compounding Engineering?
It's the opposite of how most teams work. Normally, you fix a bug, ship it, and forget it. Next month someone hits the same bug and re-solves it from scratch. Compounding engineering means each fix teaches the system. Your third code review is faster than your first because the agents learned patterns. Your tenth security audit catches issues you missed in audit #2. The work accumulates instead of evaporating.
How do agents differ from skills?
Agents are coworkers with specific jobs. The security-sentinel does security reviews. The kieran-rails-reviewer enforces Rails conventions. You call them directly: claude agent security-sentinel.
Skills are expertise Claude can tap into when needed. The dhh-ruby-style knows 37signals patterns. The gemini-imagegen knows how to generate images. Claude invokes them automatically when relevant, or you can explicitly call them: skill: dhh-ruby-style.
Why aren't MCP servers loading automatically?
Yeah, we know. It's a current limitation. The workaround is simple: manually add the MCP servers to your .claude/settings.json file. Check the README for copy-paste config. Takes 30 seconds and you're done.
Can I use this with languages other than Ruby/Rails?
Absolutely. We've got Python and TypeScript reviewers alongside the Rails ones. And the workflow commands, research agents, and skills like gemini-imagegen don't care what language you write. The security-sentinel finds SQL injection whether it's in Rails, Django, or Laravel.
How do I create my own agents or skills?
Run /create-agent-skill or invoke the create-agent-skills skill. Both give you templates, enforce best practices, and walk you through the structure. You'll have a working agent or skill in minutes instead of reverse-engineering from examples.
