get_space_news

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

No annotations are present, but the description clearly indicates a read-only operation and defines the content scope. It adds context about the types of news included, and no unexpected behaviors or side effects are suggested.

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 efficiently conveys the tool's purpose and scope.

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 zero-parameter, category-specific news getter with an output schema, the description is complete. It names the exact news category and subcategories, making it sufficient for selection among many siblings.

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 tool has zero parameters, so the baseline is 4. The description's mention of missions, science, and technology provides useful context but is not necessary for parameter understanding since the schema is empty and fully covered.

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 'Get space and aerospace news' with a specific verb and resource, and further specifies subcategories (missions, science, technology). This distinguishes it from sibling news category tools.

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 explicit usage guidance or mention of alternatives is provided. The category-specific name and description imply when to use it, but there is no direct comparison to sibling news tools.

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