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

There are no annotations, so the description carries the full burden of behavioral disclosure. It does reveal several important traits: the tool is paid ($0.01), it returns a ranked index, and it is cross-chain and exclusive in data coverage. However, it does not disclose the two-step payment requirements flow, output format, thresholds for 'near-liquidation', or any auth or rate-limit behavior, leaving a moderate transparency gap.

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 compact and front-loaded with the most important facts: payment, ranking, and scope. The second sentence adds a differentiation claim but is somewhat redundant with 'Sole-source.' Overall it is efficient with no meaningful bloat.

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?

With no output schema and no annotations, the description must supply more contextual detail than it does. It names the output fields but omits the payment flow, response shape, pagination behavior, and the criteria defining 'near-liquidation.' This is insufficient for a paid data tool of this complexity.

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 description coverage is 100%, so the schema already documents chain, limit, and x402Payment. The description adds no parameter-level meaning beyond listing output fields that are not parameters. This meets the baseline but does not compensate beyond it.

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 defines the tool as a 'Ranked cross-chain liquidation-distress index' and enumerates the returned fields (borrower, venue, chain, health factor, debt, collateral), so the core purpose is identifiable. It is not a tautology and provides concrete resource scope. However, it does not explicitly differentiate itself from the sibling farm_liquidations tool, stopping just short of full clarity.

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 offers no explicit guidance on when to use farm_distress versus alternatives such as farm_liquidations or farm_health. The 'Sole-source' claim implies uniqueness but does not state a decision criterion or exclusion. The paid nature is flagged, but the actual invocation flow is left entirely to the schema and inference.

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