A content feed for AI agents is a structured stream of source-grounded updates that an agent can store, route, cite, and use before or instead of open-ended web search.
The useful word is feed. Search starts after a question. A feed starts when a watched source changes.
That distinction matters because many agent workflows are not one-off questions. A company monitor, research dashboard, policy tracker, market brief, or newsletter app needs recurring coverage. It needs to know what changed since the last run, which source changed, when it changed, and whether the source is worth citing.
A good AI content feed should include at least a source URL, source name, published date, stable ID, concise summary, extracted signals or claims, tags, pagination, and freshness or usage state. It should also have a clear production delivery surface: REST for backend routes, webhooks for event-driven systems, S3 for durable archives, and MCP for agent-native exploration.
The thing to avoid is handing the agent a raw search result page and asking it to do all of the cleanup every time. The model can do that, but it spends tokens on work the system should have already done: dedupe, source inspection, freshness checks, extraction, classification, and citation assembly.
Synorb packages this as Streams and Manifests. A Stream is the feed scope. A Manifest is the source-grounded object the agent receives. It can include a Brief, Signals, source metadata, tags, stable IDs, and citation fields.
That gives the agent a better starting point: not "go find something," but "here is what changed in the coverage area you are responsible for, with source links attached."
Web search is still useful. You use it when the topic is unknown, the source is outside your watched coverage, or the agent needs exploratory discovery. But for repeatable work, a feed is often the cleaner primitive.
Search finds pages. A content feed keeps agent state current.
