startribune_news

Read-only

Fetch current Minnesota Star Tribune top stories from its public RSS feed. Summaries are publisher teasers, not full article text; include attribution when republishing feed content.

TDQS

A4.3/5.0
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 genuinely new context beyond them: the data comes from a public RSS feed, summaries are publisher teasers rather than full article text, and attribution is required when republishing. It still does not mention refresh cadence or feed-size limits, keeping it short of a 5.

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 sentences, both front-loaded and purposeful: the first states what is fetched and from where, the second flags the content limitation and the attribution obligation. No 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?

With an output schema present, return structure need not be explained, and with zero parameters there is no input to document. The description covers source, content nature, and reuse constraints, leaving nothing an agent needs in order to call it correctly.

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 and the input schema is empty with 100% coverage, so there is nothing for the description to clarify. Baseline 4 applies.

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 and resource: 'Fetch current Minnesota Star Tribune top stories from its public RSS feed.' The scope (top stories only, RSS source, Minnesota Star Tribune) is unambiguous even among the hundreds of sibling news tools, and no other Star Tribune tool exists that could be confused with it.

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

Usage Guidelines3/5

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

The word 'current' implies use for live headlines, but the description never states when to use this versus fetching a specific article or another outlet, nor any explicit exclusions. Usage is inferable but not spelled out.

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