news_country

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 behavioral disclosure. It only states 'get news' without mentioning any side effects, data format, pagination, or potential limitations. For a read-only tool this is thin, but acceptable for a simple fetch; still, it lacks any details an agent might need to anticipate the response.

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, front-loaded sentence with no unnecessary words. It is concise, but could include a brief mention of output type or usage context without bloating.

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?

Given the large sibling set with multiple news-related tools, the description does not provide enough context to distinguish when 'news_country' is appropriate versus 'news_category' or 'news_general'. There is no output schema, and the description doesn't explain what the news result looks like. The tool is simple, but the lack of contrast with siblings leaves the agent guessing about alternatives.

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% (the parameter 'country' has a description 'Country name or code'). The tool description adds nothing about the parameter beyond what the schema already says, so it meets the baseline of 3 without adding value.

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 'Get news for a specific country' clearly identifies the verb (get), resource (news), and a specific filter (country). It implicitly distinguishes itself from siblings like news_general (all news), news_ticker (news for a ticker), and news_category (news by category), so an agent can infer its specific scope.

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?

No guidance is given on when to use this tool versus the many news siblings (news_general, news_category, news_ticker, etc.). The description implies usage (when you want news for a country) but doesn't explicitly state exclusions or alternative conditions, leaving the agent to infer the selection logic.

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