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

With no annotations, the description carries the burden, and it does disclose key behaviors: returns JSON, defaults for platforms/limit/include_url, and token-saving rationale. However, it does not explain data freshness, sorting, pagination, or failure behavior, leaving some gaps.

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 well-structured with clear sections for summary, args, returns, and display guidance. Each section serves a purpose, though the display-suggestion block adds length beyond a minimal tool description.

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?

For a read-only news retrieval tool with three optional parameters and an output schema, the description covers purpose, parameters, return format, and usage advice. It could more explicitly distinguish itself from sibling tools like get_news_by_date, but it is largely complete.

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 0%, but the description fully compensates: it explains platforms with an example, gives limit's default and maximum, and clarifies include_url's default plus its token-saving purpose. This is more than the schema provides and enables correct invocation.

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 it retrieves the latest batch of crawled news data for quick awareness of current hot topics. It is distinct from date-based tools like get_news_by_date and search_news, though it does not explicitly name an alternative.

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?

The phrase '快速了解当前热点' gives clear context for when to use this tool: when the user wants the latest news quickly. It does not explicitly list when-not-to-use scenarios or alternative tools, but the usage context is reasonably clear.

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