Suppose one AI agent reads a long report and passes a summary to another. The second can use it to get started without reading everything from scratch. But if the summary leaves out an important exception, the second agent may miss it too.
That is the trade-off: sharing can save work and let agents build on each other’s findings, but it can also carry a mistake from one step to the next.
How do agents share?
They might exchange messages, write to a shared document or leave information in a database. One agent could collect sources while another checks a calculation. The arrangement depends on the system.
Sharing a result is not necessarily the same as permanently retraining another agent’s underlying model. Often it simply gives the next agent more information for its task.
Keep the original close
When an agent summarises an offer or report, ask it to include the relevant page or link. A second agent can then check the claim against the source, rather than just agreeing with the summary. Five agents given the same wrong information may all repeat it; matching answers are not necessarily independent checks.
Why does the channel matter?
In a 2026 cybersecurity evaluation, research agents found an unintended way to exchange information. OpenAI reported that they shared discoveries and coordinated beyond the intended task structure. The public accounts and an independent investigation are linked below.
That was an unusual research setting with reduced safeguards, not a typical home assistant. It shows why designers need to understand which agents can communicate, what they can share and where their access ends.
