getCryptoLoanFlexibleOngoingCoin

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

Annotations already declare readOnlyHint=true, so the read-only nature is covered. The description adds useful behavioral context beyond that: the 5-requests-per-UID rate limit and the fact that it reports current debt, hourly interest rate, and accrued interest.

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 summary sentence is front-loaded and clear, but the Features and Use Cases sections overlap ('Monitor accrued interest' vs 'Monitor interest accumulation', 'View current debt' vs 'Check current debt amount'). Some bullets could be trimmed without losing information.

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 one optional parameter, the description covers the main data points and rate limit. It does not describe the response shape (no output schema is present) or the behavior when loanCurrency is omitted, which are relevant gaps.

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 schema gives no description for loanCurrency, so the phrase 'by currency' is the only meaning attached to the parameter. It clarifies the currency is a filter, but it does not state what happens when loanCurrency is omitted, which matters because the schema marks it optional.

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 opening sentence names a specific verb ('Query'), a specific resource ('current flexible borrow positions'), and a filtering dimension ('by currency'). This clearly distinguishes it from fixed-term loan tools and history/report tools in the sibling list.

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 Use Cases section gives practical scenarios (checking debt, monitoring interest, calculating repayment), which implies when to call it. However, it never explicitly says not to use it for historical records or available inventory, nor names alternatives such as getCryptoLoanFlexibleBorrowHistory.

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