AgentsRoom Customize Agents: write your rules once, get your own AI coding agent in every project
A real session, filmed in the app: the shop rules you paste into Claude Code every session (prices in cents, no default exports, a test for every function) are written once in the system prompt of a custom agent, "Shop Reviewer", saved in your account. Asked to review a cart file with not one rule in the message, it answers with a short checklist that applies them: the price stored as a float, the default export, the missing tests. In another project, Add agent already offers it under Your agents.

Still pasting the same rules into Claude Code every day? This is AgentsRoom, the desktop app where your AI coding agents work side by side. Here are my shop rules: prices in cents, no default exports, a test for every function.
Every new session, I paste them again. Instead, I write them once. Add agent, then Create custom agent.
I give it a name, say what it does, and put my rules in its system prompt. It is saved in my account. Next time, I just type its name, and there it is, under Your agents.
I pick it, keep Claude and the model I want, and add it to the project. Then I ask it to review the cart file. Not one rule in my message.
Its answer is a short checklist: the price stored as a float, the default export, the missing tests. My rules, applied. And in my other project, Add agent already offers it.
Customize Agents is in AgentsRoom, with Claude Code, Codex and the other coding CLIs. The link is in the description.
