getCryptoLoanFixedRenewInfo

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

With readOnlyHint=true and openWorldHint=true annotations already establishing a safe read operation, the description adds a useful rate-limit constraint (5 requests per UID). It does not describe pagination or response behavior, but given the annotation coverage this is a reasonable supplemental disclosure.

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 short and front-loaded, with the rate limit placed after the main purpose. It has little waste, though 'and information' is slightly vague and could be more specific without hurting conciseness.

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?

For a read-only query with no output schema and four undocumented optional parameters, the description is too sparse: it doesn't describe return fields, pagination semantics, or how the parameters filter the renewal history. The rate limit is helpful but does not fill the invocation gap.

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 0%, so the description needed to explain what limit, cursor, orderId, and orderCurrency mean. It does not; it only says 'history and information,' leaving agents to guess pagination semantics and filter meaning.

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 a clear action ('Query') and resource ('loan renewal history and information'), which is specific enough to signal this tool concerns loan renewal data rather than repayment or borrowing. However, it doesn't explicitly differentiate itself from closely related siblings like getCryptoLoanFixedRepaymentHistory or getCryptoLoanFixedBorrowOrderInfo, relying mostly on the tool 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?

No guidance is given on when to choose this tool over alternatives or whether it complements other loan-history endpoints. The description implies use whenever renewal history is needed, but it never states exclusions, prerequisites, or sibling routing.

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