get_news_by_location

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It only states the core action and data source; it does not mention output behavior, sorting, pagination, rate limits, or the distinction between summary-only and full-data retrieval. The read-only nature is implied but not explained.

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

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

The description is a single, efficient sentence with no wasted words. It front-loads the action and resource. However, it is so brief that it sacrifices useful guidance, keeping it from a 5.

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

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

With five parameters, an output schema, and fifteen sibling tools, this one-sentence description is not sufficient orientation. It does not explain the period, full_data/summarize relationship, or how this tool relates to nearby news-by-keyword/site/topic tools.

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

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

Schema description coverage is 100%, so the schema already documents all five parameters. The description adds no additional parameter semantics beyond indicating that location is the primary filter, which matches the schema. The baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb-resource pair: finding articles by location via Google News. It is distinguishable from siblings like get_news_by_keyword and get_news_by_site, though it does not explicitly call out those alternatives.

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

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

There is no guidance on when to prefer this tool over the many sibling news tools. The location-based purpose is implied by the name and description, but no context or exclusions are provided for choosing between location, keyword, site, topic, or trend tools.

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