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

No annotations are provided, so the description carries full burden. It mentions date format and filtering options, but lacks critical behavioral details such as rate limits, authentication needs, pagination, error handling, or what 'latest news' entails (e.g., recency, quantity). The contact info for queries/bugs is a minor addition but insufficient.

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 poorly structured and verbose with run-on sentences, unclear formatting (e.g., 'from date' to 'To date'), and includes extraneous contact information that doesn't aid tool selection. It's not front-loaded and wastes space on non-essential details.

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 no annotations, no output schema, and an empty input schema, the description is incomplete. It fails to explain return values, error cases, or operational constraints like rate limits, making it inadequate for a news API tool that likely involves network calls and data filtering.

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?

The input schema has 0 parameters with 100% coverage, so no parameters are documented in the schema. The description compensates by explaining implied parameters like date ranges, categories, and location, adding meaningful semantics beyond the empty schema. However, it doesn't specify if these are query parameters or how to pass them.

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 states the tool 'get[s] news' with date range and filtering capabilities, which provides a general purpose. However, it's vague about the exact resource (e.g., news articles, headlines) and doesn't clearly distinguish from siblings like 'top_news_by_category_powered_by_google', which also filters news by category.

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 implies usage for time-bounded news or latest news, but offers no explicit guidance on when to use this tool versus alternatives like sibling tools for category- or location-based filtering. No exclusions or prerequisites are mentioned.

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