I spent 30 days building and polishing this Claude Code plugin for agent builders. It has 5 slash commands I use every day.
Now let me show you how magical they are and how I built and polished them over the past 30 days.
## 1st command
/generate-code-map-headers - Generate code map headers
When we use Claude Code to vibe code, sometimes it needs multiple steps to search and find the most related code and figure out the data flow trace stack, etc.
If you run it every day when you finish work, the next morning Claude will understand the code relationships in one step and code much faster.
## 2nd command
/design-refine - Iteratively refine website design to professional standards
If you're building frontend like me, you'll find it's annoying to deal with small design problems. You have to screenshot and tell Claude Code to fix them.
This slash command will run a browser agent and take screenshots of mobile and desktop at different sizes and fix the design problems.
You can also run it when you finish a day's work, and the next morning it will have fixed most of the small problems.
## 3rd command /linus-review-my-code - Get roasted for complexity (Linus-style: direct & honest)
You'll always find that Claude Code loves to add try-catch, if-else, and other over-engineering things. So you need a style guide for it, like "let it crash," or "not too many classes, just simple functions," or "no over-abstraction."
I found that this prompt makes it review code like Linus, which finds most problems. It's really good when you just finish some auto-accept edits—let this review your code and fix the problems.
## 4th command /aaron-review-my-code - Get reviewed by the creator (Aaron: educational & principled)
If you're using ConnectOnion to build agents and don't want to read documentation, but still want to build elegant agents that follow the principles "make simple things simple and make complicated things possible," then run this!
## 5th command /aaron-build-my-agent - Let Aaron build your agent (scaffolding done right)
If you want to build an agent but don't want to build it yourself, just run this and input what you want to build—let this prompt build one for you!
