setAutoRepayMode

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

Beyond annotations, it discloses the actual runtime behavior: automatic repayments at :00 and :30 every hour, no asset conversion, repayment amount formula based on min(available spot balance, current liability), and global vs per-currency scope. This gives an agent a concrete model of side effects.

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: a one-line purpose, a concise behavior paragraph, and bullet points for parameter scoping. It front-loads the core action and includes only useful operational details; no filler.

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 2-parameter config setter with no output schema, the description covers purpose, scheduling, amount determination, and parameter scoping. It could additionally state the response/success semantics or required permissions, but nothing critical is missing for correct invocation.

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 coverage is 0%, but the description compensates fully: it explains autoRepayMode='1' enables auto-repay (and '0'/disabled is implied), and it details exactly how currency omission vs specification changes behavior. Both parameters gain meaning beyond the bare schema.

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?

Description opens with 'Set spot automatic repayment mode,' naming a specific verb and resource and making clear this is a configuration write, not a manual repay/read action. It further clarifies scope (all currencies vs one), distinguishing it from related loan/repay siblings.

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 implies when to use it: enable/disable automatic spot repayment by toggling autoRepayMode. It gives clear conditions for currency omission vs specification, but it never names alternatives such as accountRepay, accountNoConvertRepay, quickRepayment, or getSpotMarginTradeAutoRepayMode, so an agent must infer tool selection.

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