getCryptoLoanCommonLoanableData

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

With no annotations provided, the description fully handles behavioral disclosure. It discloses that the endpoint is public, has a rate limit, supports filtering by currency and VIP level, and covers both flexible and fixed-term loans. It does not describe the response format, but the key behavioral traits are transparent.

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 well-structured with a short introductory sentence, clearly labeled Features and Use Cases sections, and bullet points. Every sentence adds value, and the most important information is front-loaded.

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 the tool has 2 optional parameters and no output schema, the description covers usage scenarios, filtering options, and rate limits. It does not explain default behavior when parameters are omitted, but overall it is fairly complete for a simple query tool.

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 has 2 parameters with 0% schema description coverage, but the tool description adds meaning by explaining that 'currency' allows querying by specific currency or all, and 'vipLevel' filters by VIP level. It does not specify data types or formats, which is a minor gap.

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 states the tool queries information about currencies available for borrowing, using a specific verb and resource. It distinguishes from sibling tools like getCryptoLoanCommonCollateralData by focusing on loanable data. The features and use cases further reinforce its purpose.

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 provides explicit use cases, such as checking currency availability and viewing interest rates, and mentions that it is a public endpoint. However, it does not explicitly state when not to use this tool or compare with alternatives like other crypto loan query tools.

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