get_latest_news

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

No annotations exist, so the description carries full burden. It discloses that include_url=false saves tokens, and explains default display behavior. It does not explicitly state read-only or nondestructive nature, but the context implies it.

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?

Description is structured with Args, Returns, and display suggestions. It is clear but slightly verbose with the display suggestions; could be more concise.

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 output schema exists, return value explanation is sufficient. Parameter descriptions are thorough, and display suggestions complete the usage context. Comprehensive for a list-style tool.

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%, so description fully compensates. Each parameter is explained: platforms (list, defaults all), limit (0-1000, default 50), include_url (default false, token-saving). This adds crucial semantics.

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 gets the latest batch of crawled news data for understanding current hotspots. It uses specific verbs and distinguishes from siblings like get_news_by_date and search_news.

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 description provides display suggestions but does not explicitly compare with sibling tools like get_news_by_date or search_news. The advice on data presentation is helpful, but when-to-use guidance is missing.

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