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

With no annotations, the description carries the burden of behavioral disclosure, and it does communicate access requirements, costs, default window size, and the effect of omitting the chain parameter. However, it does not state whether this is a read-only operation, whether pagination or rate limits apply, or how authentication failures behave.

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 appropriately sized and has no filler wording; it explains access, payment, data shape, and window semantics in a compact form. It is slightly disadvantaged by leading with the long payment/auth sentence before stating what the tool actually does, but every sentence serves a purpose.

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 only two optional parameters and the presence of an output schema, the description covers the essential calling context: the data being retrieved, chain optionality, and window constraints. It could be slightly clearer that 'per chain, protocol and direction' describes output categories rather than input parameters, but overall no critical call-time information 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?

The input schema only provides 'chain' and 'window' with no units, ranges, or defaults. The description adds critical meaning: 'window in hours, default 24, max 720' and 'Omit chain for all.' This directly compensates for the absence of schema descriptions and makes both parameters clear enough to call the tool correctly.

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 that the tool returns lending liquidation data per chain, protocol, and direction over a window, including event counts, borrowers, liquidators, debt covered, and collateral liquidated. It is clear about the resource and scope, though it lacks an explicit verb and does not directly distinguish itself from sibling tools by name.

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 gives no guidance about when to choose this tool over the many available sibling tools, nor does it mention alternatives or exclusion cases. The only usage hints are 'Omit chain for all' and the window defaults, which are parameter-level details rather than tool-selection guidance.

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