Where a task falls apart as it passes through three agents

Picture a workflow. Three agents handle it: agent A does the research, agent B does the analysis, agent C writes the final output. A's results feed B, B's feed C, you read what C produces. On paper, this is the part that should already be working.

It isn't. The interesting thing is that it falls apart in four different places, and each one looks like a separate problem until you sit with it for a while.

First, the handoff. Agent A, B, and C are built by three different teams. How do they find each other, and how does A's output actually get into B? Right now, the answer is you. You copy-paste between tabs. Or someone wrote a brittle custom integration that breaks the first time A changes its output schema. There's no shared standard for one agent to hand work to another built by a different team.

Second, the trust. Suppose the handoff works. How does B know A's output is correct? How do you know C's final report is built on accurate intermediate results? Nobody is independently checking. Worse: if anything in the chain quietly alters A's data in transit, the final output still looks normal. You'd never know it was tampered with. There's no shared way for agents to verify each other's outputs.

Third, attribution. Three agents did the work. How are credit and payment split? Right now, whichever platform sits in the middle decides, or there is no mechanism at all. There's no neutral record of who contributed what, or what each is owed.

Fourth, discovery. When the next task comes around, the agent that did well this time isn't the one that gets found. Nothing surfaces agents by actual performance; what gets seen is whatever has marketing behind it.

These look like four separate problems. They aren't. Handoff, verification, attribution, discovery: what's missing in every one of them is the same thing. There's no shared layer for these agents to stand on. Each agent is locked inside the platform it runs on.

This is what I keep coming back to. You can't solve any one of these in isolation, because the next one still breaks. A clean handoff doesn't help if the output can't be trusted. Verification doesn't help if no one can find the agent that was verified. Discovery doesn't help if the way it ranks agents isn't fair. They have to be one layer, or they are nothing.

That layer is going to get built. The only question is whether it's open, neutral, with rules anyone can read, or whether it's another platform you have to depend on.
The agents are here. What's underneath them isn't yet.
