execute_transfer

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

No annotations provided, so the description must compensate. It discloses idempotency behavior and network support, but does not mention side effects, auth requirements, rate limits, or async nature, leaving gaps.

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 paragraph of 4 sentences, front-loaded with the main purpose. It is reasonably concise, though structured lists for networks could improve readability.

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 the tool has 8 parameters (7 required) and an output schema, the description covers purpose, idempotency, and networks, but misses explanation of customer_id, error handling, or result format, making it incomplete for complex use.

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%. The description explains required parameters like source_id, destination_id, amount, currencies, networks, and lists supported networks. However, it omits the optional customer_id parameter entirely, and lacks format/examples.

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 clearly states it executes a money transfer with automatic idempotency, explicitly listing required parameters and supporting networks. It distinguishes from sibling tools like get_transfer or list_transfers as a write operation.

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 explains what parameters are needed and mentions idempotency and supported networks, but lacks explicit guidance on when to use this tool versus alternatives (e.g., submit_cctp_offramp) or when not to use it.

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