postCryptoLoanFixedRepayCollateral

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. The description adds value by clarifying the collateral-to-loan-currency conversion mechanism and disclosing a rate limit of 1 request per UID. It does not contradict the annotations, but it does not describe post-action effects or reversibility beyond what annotations imply.

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 two sentences with no filler. The core action is front-loaded, and the rate limit is cleanly separated. Every sentence earns its place.

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 destructive mutation tool with 5 required parameters, no output schema, and no parameter descriptions except confirm, this description is incomplete. It lacks preconditions, post-action effects, amount semantics, and any indication of what the response contains. The confirmation parameter's description helps, but the tool-level description leaves too much for the agent to infer.

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 only 20%, with the confirm parameter carrying the only detailed schema description. The description gives some relational context between collateralCoin and loanCurrency, but it fails to clarify critical semantics such as whether 'amount' refers to collateral amount or loan amount, how loanId is obtained, or the expected format of coin/currency identifiers.

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 specific action: 'Repay loan by converting collateral to loan currency.' This clearly identifies the verb, resource, and mechanism. It does not explicitly distinguish itself from sibling tools like postCryptoLoanFixedFullyRepay or postCryptoLoanFlexibleRepayCollateral, so it falls just short of a 5.

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 no guidance on when to prefer this tool over alternatives such as accountRepay, quickRepayment, postCryptoLoanFixedFullyRepay, or postCryptoLoanFlexibleRepayCollateral. It implies the use case through the name and action, but does not state conditions, exclusions, or alternatives.

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