Chat-mode live milestones now use friendlier wording for the agent's tool calls and observations. ``Tool: search_pubmed — "covid"`` becomes ``🔍 Searching PubMed: "covid"``, ``Tool: fetch_url — "https://…"`` becomes ``📖 Reading the page: "https://…"``, and tool results show as ``📄 From {engine}: …`` so the thinking-text reads like a narration of what the agent is doing rather than a dump of internal tool names. Engines without an explicit display name fall back to a cleaned ``Title Case`` form of the raw tool name, so newly added search engines work without a code change.
