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

With no annotations, the description carries the full load. It discloses non-obvious behavior: FIAT auto-conversion, a yes/no confirmation gate, and the same-blockchain constraint. But it is silent on irreversibility, fees, permission/auth requirements, and rate limits — important for a high-stakes wire operation.

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?

Purpose is front-loaded and the @param block is well organized, but the opening sentence is duplicated verbatim, which is pure waste. The '@return: a json object' line is uninformative 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 7-parameter mutation with no annotations and no output schema, the description covers parameters and core mechanics but leaves gaps around auth, fees, failure modes, and the actual response shape. Adequate but short of complete for a funds-transfer tool.

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 compensate, and it does document every parameter via @param lines. It adds genuine meaning beyond types, e.g. account_fk is a DB ID not an address and may not be 0, and digital_asset_fk=0 means FIAT.

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?

States a specific verb and resource ('Sends FIAT or Digital Assets from this account to a blockchain address') and adds the material scope detail that FIAT is converted by the system. This is enough to distinguish it from fund-moving siblings like account_send or withdraw_to_bank, though it never names an alternative explicitly.

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?

Implicit usage is clear (move funds out of an account) and it states a real prerequisite ('The FIAT account must be associated to the same blockchain as the destination address') plus a confirmation requirement. However, it never says when to choose this over account_send, account_pay, or crypto_spend, so routing between siblings is left to inference.

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