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

Annotations already declare this read-only, idempotent, and closed-world, so safety is covered. The description adds useful relational context: each method has a `code` used by other tools, and search spans name, currency, code, or network. It does not describe return shape, ordering, or whether the method list is static, which would help for a lookup tool.

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 purpose is front-loaded and the description is short. The `code` and `search` details are relevant. Formatting with hard line breaks is slightly awkward but not wasteful.

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, so the description should explain enough about the returned methods. It mentions each method has a `code`, but it does not describe other likely fields or how `side` and `lang` affect results. Adequate for a simple lookup, but with clear 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?

Schema description coverage is 0%, so the description must carry parameter meaning. It explains `search` well with concrete examples, but leaves `side` and `lang` substantially undocumented. The give/receive framing hints at `side`, but it does not explain the `all` default or the language toggle.

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?

It clearly states the resource: pay methods of the exchange, split into what the client can give and receive. The verb is implicitly "list," but the purpose is unmistakable. It does not explicitly distinguish itself from the sibling list_receive_options, which is the main clarity gap.

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 browsing available payment methods but gives no explicit guidance on when to use this tool versus list_receive_options, get_quote, or get_reserves. There are no exclusions or routing cues for an agent choosing among siblings.

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