:root { --color: blue; }
  div { --color: green; }
  #alert { --color: red; }
  * { color: var(--color); }

  <p>I inherited blue from the root element!</p>
  <div>I got green set directly on me!</div>
  <div id='alert'>
    While I got red set directly on me!
    <p>I’m red too, because of inheritance!</p>
  </div>

It seems every object is given variables (--abc). And then there are global variables and local variables. I guess this is the "cascading" feature. var is a function computed at the time of instantiation. And refers to local variables first. Then looks at global variable. Inheritance comes from ?? The p tag seems it is not root so therefore it is not blue.

Having explained it, I think about it better, but this really messes up how I thought of CSS. CSS is where the second stanza overwrites the first stanza. Yet global and local variables really hurts my head. A few complex CSS files later, it is bound to be unusable to determine result without getting a computer program to help.

Each agent builds up state via tool use. On each loop of the network, you inspect this state to figure out which agent to run next. You don't build DAGs or create odd graphs — you write regular code in a router.

Or, more generally:

* Each agent has a specific goal within a larger network. Several agents each working on smaller goals means easier prompt generation, testing, iteration, and a higher success rate.

* The network combines agents to achieve an overall objective, with shared state modified by each agent

* The network’s router inspects state and determines which agent should run next

* The network runs in a loop, calling the router on each iteration until all goals are met

* Agents run with updated conversation history and state on each loop iteration

Realistically the challenge with agents has classically been: how can I build something reliable, and how can this run in production reliably? These patterns are largely what we've seen work.
