        "Microsoft Research published “Magentic-One: A Generalist Multi-Agent System for Solving Complex Tasks” on November 4, 2024. The article introduced a system with an orchestrator and specialist agents, including web-surfer, file-surfer, coder and computer-terminal roles. It described benchmark comparisons on GAIA, AssistantBench and WebArena. The associated technical paper provides the experiment details and reported results.",
        "The publication is research evidence about a specified system and evaluation setup. It is not proof that a comparable agent deployment will complete a reader’s tasks safely, have access to the same tools, or behave the same after a model, prompt or browser change."

      "paragraphs": [
        "A multi-agent run should record the task, planner decision, delegated subtask, allowed tools, inputs, outputs, time limit and stop rule for each agent. Without that trace, a final answer can hide whether the system searched, wrote code, used stale context or failed to complete a required check. A transcript alone is often too noisy; a structured receipt makes review practical.",
        "Declare which agent may propose, execute or only inspect. A coding agent that writes a patch should not also be treated as the approver of that patch. An orchestration layer can route work, but it should not erase human authority or turn an unverified subagent claim into an external action."

      "paragraphs": [
        "Agent benchmarks join a task set, environment, tool availability, timeout, scoring procedure and often a model choice. Changing any of those can change the result. Before comparing a local system with a paper result, reproduce the task contract as closely as allowed, state every deviation and retain the raw outcomes. Measure failure modes, not only solved tasks: loops, unsafe proposals, missing evidence, tool errors and uncertain external state.",
        "Use a small production-relevant harness before expanding scope. Include tasks that require refusal, approval, source citation and recovery from a failed tool call. This is original evaluation guidance; it does not reinterpret the reported Magentic-One benchmark results."

      "paragraphs": [
        "This article records Microsoft Research’s November 4, 2024 publication and paper. It does not claim current code availability, model configuration, benchmark ranking, security posture or suitability for an unattended workflow. Those require current source and deployment-specific evidence.",
        "The lasting practice is simple: retain an accountable run record for every delegation and reconcile uncertain actions before retrying. That is stronger than trusting an orchestration label. Include prompt and configuration digests so a later incident review can identify changed instructions without retaining more content than necessary. Test records under parallel delegations, where timing alone cannot identify which result belongs to which request. Keep the final owner identifiable."
