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

The annotations already state readOnlyHint=true, openWorldHint=false, and idempotentHint=true, so the safety profile is covered. The description adds almost nothing beyond that: it does not explain result shape, filtering behavior, localization behavior, pagination, or what happens with an unknown method code.

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, which is structurally efficient. However, the parenthetical '(by its `code`)' is slightly confusing because the parameter itself is named `give`, and the sentence is too terse to structure the three-parameter behavior.

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?

There is no output schema, three parameters with 0% schema description coverage, and only one sentence of description. The annotations cover read-only/idempotent behavior, but the definition still lacks enough detail about inputs and return values for an agent to invoke it confidently.

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 0%, so the description must explain all three parameters. It only hints that 'give' relates to a method code, and it says nothing about the `lang` enum or the nullable `search` parameter. This leaves the agent guessing about accepted values and filtering semantics.

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 conveys that the tool returns receive options for a method supplied by code, so the broad purpose is inferable. However, it never explicitly says it lists options, and 'what the client can receive' is ambiguous without domain context. It does not clearly distinguish itself from list_pay_methods or other 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?

There is no guidance on when to use this tool versus list_pay_methods or other siblings, no exclusions, and no prerequisites. The only usage signal is the implicit dependency on a method code, which is not enough to route an agent reliably.

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