news_search

Read-only

Search recent news and return ranked articles with titles, URLs, and snippets. Retrieve current events and headlines for time-sensitive queries.

Instructions

Search recent news and return ranked articles (title, url, snippet) — current events, headlines, timely reporting. This is search locked to topic: news; same options as search (domain / text filters, language filter, time window, highlight / full_content, media) except topic, which is fixed to news.

For a single news lookup this is the right tool. For a multi-angle news question ("what shipped across the industry this month", "how are different outlets covering X"), use broad_search with topic=news instead of looping news_search.

keywords: news search, latest news, headlines, current events, breaking news, recent, today, this week, press coverage

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
countNoNumber of results to return (1-100). Default 5.
queryYesNon-empty search query. Max 500 chars.
formatNoFormat of returned content. Default text.text
timeoutNoRequest timeout in seconds (1-60). Defaults to 30s if unset.
end_timeNoUpper bound for the time window, ISO 8601.
languageNoLanguages to filter results by, as ISO 639-1 codes. Empty = no filter.
highlightNoReturn a ranked highlighted snippet per result. Omit to use the server default.
safesearchNoAdult-content filter. Default strict.strict
start_timeNoLower bound for the time window, ISO 8601 (e.g. '2025-01-01T00:00:00Z').
time_basisNoWhich timestamp the time window filters against: page `published` date, last `crawled` date, or `auto`. Default auto.auto
time_rangeNoRelative time window (e.g. `week`, `month`). Mutually exclusive with `start_time`/`end_time` — if both are given, the absolute range wins.
exclude_textNoDrop results whose content contains any of these strings. Max 5, each ≤30 chars.
full_contentNoReturn the cleaned full page body per result. Heavier than `highlight` — use only when the snippet isn't enough. Omit to use the server default (off).
include_textNoOnly return results whose content contains all of these strings. Max 5, each ≤30 chars.
include_imagesNoReturn image URLs (and a cover image) found on each result page.
exclude_domainsNoDrop results from these domains. Max 1200, each ≤60 chars.
include_domainsNoOnly return results from these domains (e.g. 'arxiv.org'). Max 1200, each ≤60 chars.

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already mark the tool as read-only, open-world, and non-destructive, so the description does not need to repeat that. It adds useful behavioral details beyond annotations: output is ranked articles with title/url/snippet, supports highlights/full content/images, and applies time-window and domain filters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core description is concise and front-loaded with purpose and usage guidance. The trailing 'keywords' line is mildly redundant with the first sentence, but the overall structure is clean and easy to scan.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 17 parameters and no output schema, the description adequately summarizes the return shape (ranked articles with title, url, snippet) and main capabilities (time windows, filtering, highlighting, full content, images). It does not specify response envelope details like pagination or error codes, but those are commonly implied in such tools and not critical for basic invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and each parameter has a clear explanatory description with defaults and constraints. The description adds extra semantic guidance for parameters like `full_content` (heavier than highlight, use only when snippet isn't enough) and `time_range` (mutually exclusive with absolute times).

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool searches recent news and returns ranked articles with title, url, and snippet. It explicitly distinguishes this tool from `search` (locked to topic news) and from `broad_search` (for single vs multi-angle queries).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives concrete guidance on when to use this tool versus `broad_search`: use for a single news lookup, use `broad_search` for multi-angle questions. It also clarifies that this is `search` with topic fixed to news, so options are inherited from `search`.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
