NOS

Use this for vague or date-driven news requests when the user does not give a real topic. After calling this tool, show the widget and the tool's one-sentence content only. Do not summarize, interpret, or explain the articles unless the user explicitly asks for a summary. Call only this NOS tool for one user prompt; do not also call `search_articles`. Examples: - "latest news" - "most important news" - "anything happened two weeks ago?" - "what was in the news last week?" - "what happened around 2026-03-10?" Set `start_date` and `end_date` to match the requested period. Do not invent a specific topic query. Do not use this when the user gives a specific topic, person, event, or keyword. This tool returns the best recent cards for that period.

latest_articles

Use this when the user wants the 4 most relevant NOS articles for a specific topic, person, event, or keyword. After calling this tool, show the widget and the tool's one-sentence content only. Do not summarize, interpret, or explain the articles unless the user explicitly asks for a summary. Call only this NOS tool for one user prompt; do not also call `latest_articles`. Keep the words that make the question specific. Both of these work: - "waarom zijn er zo veel boten in Amsterdam" - "veel boten Amsterdam Canal Parade" Put time expressions in `start_date`/`end_date`, not in the query text: "waarom zijn er zo veel boten in Amsterdam vandaag" becomes query="veel boten in Amsterdam" with start_date and end_date both set to today. Do not narrow the window further than the user asked for: the tool always fills the cards from the window, so too narrow a range returns unrelated articles. Leave both dates unset when the question names no period of its own. "Wat is het laatste nieuws over Trump?" asks about a topic, not about today: query="nieuws over Trump" with no dates. Restricting that to today hides the story that has been running all week. Do not reduce it to a bare topic, which drops the words that disambiguate: - "Amsterdam" (matches any Amsterdam news, including a fatal boat accident) - "stemming" (a vote in parliament, or the mood — both match) - "spits" (a striker, or rush-hour traffic) Do not use generic phrases in the query like: - "latest news" - "recent headlines" - "most important news" For generic recent or important news without a topic, use `latest_articles` instead. `start_date` and `end_date` control the date window for recency filtering. Returns exactly the top matching cards for display.
