TDQS

A4.4/5.0
Behavior5/5

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

Even though annotations already mark this as destructive and non-read-only, the description adds meaningful behavioral context: no penalty for early repayment, interest is calculated only up to repayment time, partial/full repayment is allowed, and there is a rate limit of 1 request per UID. This goes beyond the annotations without contradicting them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well structured with a one-sentence summary, feature bullets, and use-case bullets. Every bullet adds useful information, and the most important purpose is front-loaded. There is no redundant or filler content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core action, key features, use cases, and rate limit, which is strong for a repayment tool. However, it omits some preconditions and edge cases, such as requiring an existing flexible loan position, the need for sufficient repayable balance, and behavior when the repayment amount exceeds the outstanding loan. These gaps are minor but noticeable for a destructive financial action.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 33%, so the description must compensate for the undocumented 'amount' and 'loanCurrency' parameters. It partially does by indicating repayment uses the loan currency and that partial/full amounts are supported, but it does not specify amount format, decimal rules, minimum amount, or how loanCurrency relates to the existing loan position.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a clear action and resource: 'Repay flexible loan with loan currency.' The feature list further clarifies partial/full repayment and interest behavior. The phrase 'with loan currency' distinguishes this from the sibling postCryptoLoanFlexibleRepayCollateral, and 'flexible' distinguishes it from fixed-loan repay tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'Use Cases' section provides explicit situations for using this tool: repaying when funds are available, partial repayment to reduce interest, and full repayment to release collateral. It does not explicitly name alternative tools or state when not to use this tool, so it falls short of a 5, but the context is clear.

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