ransomlookGroups

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the return type (582+ groups), the fields (names and URLs), and the data source (RansomLook). For a read-only listing operation, this is adequate transparency, although it omits details like pagination or rate limits.

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 two concise sentences, front-loaded with the core purpose ('List all ransomware groups tracked by RansomLook'), followed by output details and source context. Every sentence earns its place with no redundancy or filler.

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, read-only list tool with no output schema, the description is complete. It explains exactly what is returned (582+ groups with names and URLs), identifies the data source, and positions it relative to ransomware.live. No critical information is missing for an agent to invoke and interpret the results.

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 as per the rubric. The description adds value by explaining what data is returned, which is useful even though no parameter documentation is needed.

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 uses a specific verb ('List') and resource ('all ransomware groups tracked by RansomLook'), clearly stating the output ('582+ groups with names and associated onion/clear-web URLs'). It also distinguishes itself from siblings by noting it is 'Complementary source to ransomware.live', which differentiates it from the similarly named 'ransomwareGroups' tool.

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 clear usage context by indicating this is a complementary source to ransomware.live, implying it should be used when RansomLook data is desired, possibly alongside ransomware.live data. It does not explicitly exclude alternatives or name sibling tools, but the context is sufficient for guiding tool selection.

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