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

With no annotations, the description carries the disclosure burden. It adds a payment requirement/cost ('PAID $0.01') and outlines what data will be returned, but it does not explicitly state read-only behavior, side effects, or failure modes, leaving the safety profile implicit.

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-loads the payment fact, followed by a dense but mostly valuable metric list. There is no filler, though the run-on comma-separated output list could be structured more cleanly.

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?

It lists the key output fields, which is critical because there is no output schema, and it states the venue/chain granularity. However, it does not describe the response shape, grouping, or usage boundaries, and with no annotations the read-only nature is left unstated.

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 100% and the schema already explains the two-step x402Payment flow. The description adds only the fee amount, which is useful context but not additional invocation semantics, so it meets the baseline.

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 names a specific resource scope ('cross-venue lending stress') and enumerates the exact metrics returned (positions at risk, debt at risk, liquidatable count, health factor). It lacks an explicit verb and does not name sibling tools, so it stops short of full differentiation, but the purpose is concrete.

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 implies a use case: when a cross-venue/chain lending stress snapshot is needed. It provides no explicit when-to-use guidance, exclusions, or alternatives among the many farm_* siblings, so an agent must infer when this is the right endpoint.

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