list_aggregators

Retrieve a ranked list of DEX, bridge, or yield aggregators filtered by volume, fees, and supported chains. Specify the aggregator kind to get curated results.

Instructions

DEX, bridge, or yield aggregators ranked by volume, fees, chain support. Required: kind ∈ {dex, bridge, yield}.

Tool call template

TDQS

A4/5.0
Behavior2/5

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 ranking criteria but does not disclose behavioral traits such as pagination, rate limits, or the maximum number of results returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise, with one sentence and a parameter hint, all front-loaded. Every part adds value without redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter, no output schema), the description covers the purpose, required input, and ranking criteria. It lacks details on result count or filtering, but these are minor for a straightforward list tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides 100% coverage for the single parameter, but the description adds semantic value by specifying the ranking dimensions (volume, fees, chain support) beyond the parameter's enum definition.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists DEX, bridge, or yield aggregators ranked by volume, fees, and chain support, with a required 'kind' parameter. This distinguishes it from sibling tools, which are mostly get_ or list_ operations on different entities.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly specifies the required 'kind' parameter and its valid values, providing clear guidance on how to use the tool. However, it does not mention when to use this tool versus alternatives or when not to use it.

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