malpedia_family_profile

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

With no annotations, the description carries the full burden. It explicitly discloses the MALPEDIA_API_KEY requirement, which is a meaningful behavioral constraint. The 'Get' verb implies a read-only operation, but the description doesn't explicitly state that there are no side effects or describe error behavior.

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?

Two concise sentences, with the action and content front-loaded and the API key note at the end. No filler or repetitive phrasing.

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 single-parameter lookup with no output schema, the description is complete: it states the required input, the API key prerequisite, and the profile contents the agent can expect. Nothing essential is missing.

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 coverage for the sole parameter is 100%, and the schema already describes family_name with examples. The tool description adds no additional parameter-level meaning, so the baseline score of 3 is appropriate.

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?

States a specific action ('Get') and resource ('full Malpedia malware family profile') and lists returned contents. It is clear and distinct from malpedia_actor_profile by resource, but it doesn't explicitly differentiate itself from malpedia_search or other family-related 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?

Implies use when a full family profile is needed, which is some guidance, but it never states when not to use it or names alternatives like malpedia_actor_profile or malpedia_search. The context is inferred rather than explicit.

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