defi_get_aggregators

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 only says 'Get... data,' with no details about scope, filtering, output format, or whether it returns a list, aggregate, or per-protocol details. This is minimal but not entirely absent.

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 sentence and front-loaded, which is efficient. However, it is under-specified and lacks useful context, so it is not a model of conciseness that earns its place—it just barely meets the minimum.

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 the large number of similar sibling tools and the absence of an output schema, the description is incomplete. It does not explain what 'aggregators' refers to, how the data is presented, or how this tool differs from closely related volume tools.

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, and the schema is empty. Per the rubric, a baseline of 4 applies when there are no parameters. There is nothing to add beyond the empty schema.

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 a specific verb ('Get') and resource ('DEX aggregator volume data'), so it is more than a tautology. However, 'aggregators' is ambiguous and not differentiated from similar sibling tools like defi_get_dex_volume or defi_get_chain_dex_volume, making the purpose vague.

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 guidance is provided on when to use this tool versus alternatives. Many sibling tools also retrieve volume data, and the description does not mention exclusions, prerequisites, or distinguishing use cases.

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