news_search

Search recent news articles by query and retrieve ranked results with titles, URLs, and snippets. Use for current events and timely reporting.

Instructions

Search recent news with Octen and return ranked articles (title, url, snippet). This is web search locked to topic: news — use it for current events, headlines, and timely reporting. Same options as search (domain / text filters, time window, highlight / full_content, media) except topic, which is fixed to news.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
countNoNumber of results to return (1-100). Default 5.
queryYesSearch query. Max 500 chars.
formatNoFormat of returned content. Default text.text
timeoutNoRequest timeout in seconds (1-60).
end_timeNoUpper bound for the time window, ISO 8601.
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.
include_videosNoReturn video URLs found on each result page.
exclude_domainsNoDrop results from these domains. Max 150, each ≤30 chars.
include_domainsNoOnly return results from these domains (e.g. 'arxiv.org'). Max 1000, each ≤30 chars.
Behavior3/5

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

No annotations provided, so description carries burden. Describes it as locked to news topic and returns ranked articles, but lacks details on rate limits, errors, or auth. Adequate but not rich.

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

Conciseness5/5

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

Two efficient sentences: first states purpose and output, second compares to sibling. Every sentence earns its place.

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?

All parameters documented, output format described (title, url, snippet), and relationship with sibling clarified. Lacks details on empty results or edge cases, but sufficient for typical use.

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

Parameters3/5

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

Schema coverage is 100%, so description doesn't need to compensate. It mentions categories like domain/text filters but adds no new meaning beyond what's in the parameter descriptions.

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?

Clearly states it searches recent news with Octen, returns ranked articles with title/url/snippet, and distinguishes from sibling 'search' by being locked to news topic.

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?

Explicitly says use for 'current events, headlines, timely reporting' and notes it has same options as search except topic fixed to news, providing clear guidance on when to use vs sibling.

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