variety_news

Read-only

Fetch Variety top stories from the public feed; returns headline items from the general top-story stream. For a section-specific list, use variety_headlines with a supported section slug. Use variety_article with a returned article URL when you need one story's body.

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds useful behavioral context beyond that – it is a public feed and returns headline items from the general stream rather than full bodies. It stops short of describing pagination or result limits, but is solid given annotations.

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?

Three tight sentences, front-loaded with the primary action and followed by two routing cues. Zero filler; every sentence earns its place.

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

Completeness5/5

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

Fully adequate for a no-param list tool. Return format is covered by an output schema, safety by annotations, and cross-tool routing is spelled out, so nothing an agent needs to invoke it correctly is missing.

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?

The tool takes zero parameters, so the baseline is 4. There is nothing for the description to disambiguate, and it correctly signals the no-argument nature by simply describing the fetch.

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?

States a specific verb (Fetch) and resource (Variety top stories) with scope (from the public feed, general top-story stream). It clearly distinguishes itself from the sibling family by naming the section-specific and article-body variants explicitly.

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 routes the agent: use variety_headlines for section-specific lists (with a section slug) and variety_article when a story body is needed. Both alternatives and the conditions that select them are named.

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