usmagazine_news

Read-only

Fetch Us Weekly top stories from the public feed; returns headline items from the general top-story stream. For a section-specific list, use usmagazine_headlines with a supported section slug. Use usmagazine_sections to discover section slugs.

A4.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the feed is public and what it returns (headline items from the general top-story stream), which is useful but thin — no auth, rate-limit, or freshness/recency context is disclosed.

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, each earning its place: purpose, alternative, and discovery path. The scoping statement is front-loaded and there is zero filler.

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?

An output schema exists, so return values needn't be explained, and a zero-param read tool needs little else. The description covers purpose, the routing alternative, and slug discovery, leaving no gap an agent needs to fill before calling.

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 schema carries no parameter semantics to document. Baseline 4 applies; nothing in the description contradicts or obscures this.

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 (Us Weekly top stories from the public feed), and explicitly scopes it to 'the general top-story stream' to distinguish it from the section-specific sibling. An agent can tell it apart from usmagazine_headlines without opening a schema.

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 names the alternative for section-specific lists (usmagazine_headlines with a section slug) and routes the agent to usmagazine_sections to discover slugs. This is clear when-to-use, when-not, and prerequisite discovery all in one.

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