getCryptoLoanFlexibleRepaymentHistory

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

No annotations are provided, so the description must fully disclose behavioral traits. It mentions features like querying by repayment ID or currency, pagination support, and viewing details including principal and interest. It also notes a rate limit. However, it does not specify pagination mechanics (e.g., cursor usage), whether results are ordered, or if both completed and pending repayments are included. This leaves gaps in transparency.

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 bullet points and sections (Features, Use Cases). It is appropriately sized and front-loaded with the core purpose. While clear, some sentences (e.g., 'Rate limit: 5 requests per UID') could be integrated more succinctly. Overall, it earns its space.

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 absence of an output schema, the description should provide more detail on return values. It mentions 'repayment details including principal and interest' but does not describe the full response structure, pagination metadata, or behavior for empty results. With 4 parameters (0 required) and moderate complexity, the description is somewhat complete but leaves users guessing about the response shape.

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 4 parameters with 0% schema description coverage. The description adds basic semantics: 'Query by repayment ID or currency' maps to repayId and loanCurrency, and 'Pagination support' maps to limit and cursor. However, it does not clarify that no parameters are required, nor does it explain parameter formats or allowed values. The added value is limited.

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 'Query historical flexible repayment records with pagination,' specifying the verb (Query) and resource (flexible repayment records). It distinguishes itself from sibling tools like getCryptoLoanFlexibleBorrowHistory and getCryptoLoanFixedRepaymentHistory, which target different aspects of crypto loans.

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 lists explicit use cases: 'Track repayment history, Verify repayment transactions, Calculate total interest paid.' It also mentions a rate limit as a usage constraint. However, it does not provide guidance on when not to use this tool or compare it to similar tools (e.g., fixed repayment history), leaving some ambiguity.

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