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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does surface that a ChainHelix API key/bearer token is required and that each call has a cost, which is useful context. However, it does not describe rate limits, error behavior, empty responses, or pagination, leaving the behavioral picture incomplete.

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 content is dense and mostly high-signal, but it opens with the auth/payment block rather than stating what the tool does. A front-loaded description starting with 'Get lending liquidations...' would make tool selection much easier.

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 two optional params and an output schema, the description covers the required essentials: purpose, filter semantics, defaults, auth, and cost. It does not cover edge-case behavior explicitly, but for a simple query-style tool this is reasonably complete.

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 is 0%, so the description must compensate, and it does meaningfully: it explains window as hours, gives the default and maximum values, and clarifies that omitting chain returns all chains. The chain enum still supplies the allowed values, but the description adds practical parameter semantics the bare schema lacks.

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 identifies the resource as lending liquidations and enumerates the returned dimensions: event count, borrowers and liquidators, debt covered, and collateral liquidated. It lacks an explicit verb like 'fetch' or 'get' and does not explicitly distinguish itself from sibling tools, but the resource and metrics are specific enough.

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?

It gives concrete invocation guidance: window is measured in hours, defaults to 24, has a maximum of 720, and chain can be omitted to query all chains. It does not explicitly discuss when not to use this tool or mention alternatives, but the call behavior is clear.

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