repay_to_lending

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not disclose that this is a state-changing transaction, that it requires a prior borrowing position, or that gas fees/network interactions apply. It also does not mention any risks or side effects beyond the literal act of repaying.

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 a single, front-loaded sentence with no wasted words, making it highly concise. It could be slightly more informative by mentioning partial repayment or protocol names, but the structural efficiency is strong.

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 that this is a complex transaction tool with six parameters, no output schema, and no annotations, the one-line description is insufficient. It omits crucial context such as whether 'amount' supports partial repayment, the role of interestRateMode, and what happens after repayment (e.g., transaction hash, position update).

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 100%, with all six parameters individually described in the input schema. The tool description itself adds no parameter-level information, so the baseline score of 3 is appropriate; it neither enhances nor harms the schema's clarity.

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 'Repay borrowed assets to a lending protocol' clearly states the action (repay) and the resource (borrowed assets in a lending protocol), which is distinct from sibling operations like borrow_from_lending and withdraw_from_lending. However, it lacks explicit mention of repaying an existing debt position or the protocol-specific context, so it falls short of a perfect score.

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 use this tool versus alternatives such as borrow_from_lending or withdraw_from_lending. It does not mention prerequisites like an existing debt position, nor does it clarify scenarios where partial vs full repayment is appropriate.

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