TDQS

A4.7/5.0

Behavior5/5

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

Beyond the readOnlyHint annotation, the description reveals meaningful behavioral characteristics: the statistical z-score threshold, trailing average comparison, weekly comparison window, 3-hour derivation cadence, and GDELT source across 65+ languages. This tells an agent what kind of computation and freshness to expect without opening an output schema.

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?

The description is a single sentence that front-loads the core question ('What's surging in global news right now') followed by high-value specifics: statistical thresholds, time comparison, language coverage, and refresh cadence. Every clause adds distinguishing information, with no filler or repetition.

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 no parameters, no required arguments, readOnly annotations, and an output schema present, the tool is simple to invoke. The description supplies the remaining context an agent needs: what trending means, how often it updates, where the data comes from, and what scale of language coverage to expect. Nothing essential 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 input schema has zero parameters, so there is nothing to document. The description correctly avoids inventing parameter syntax and instead clarifies what the tool returns conceptually. The baseline of 4 for zero-parameter tools is appropriate here.

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 identifies the resource as global trending news and defines precisely what counts as trending: topics at least 2 standard deviations above their trailing average, week-over-week movers, and surging countries. This specificity distinguishes it from sibling tools like get_topic or get_country by emphasizing a global, statistical aggregation rather than a single entity or story.

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

Usage Guidelines4/5

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

The phrase 'right now' and the global framing provide clear context for when to use this tool: when an agent needs current worldwide news surges rather than a specific country, topic, or wire. It does not explicitly name sibling alternatives or say when not to use them, so it falls short of a 5, but the context is clear enough for correct selection.

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