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

With no annotations, the description carries the burden of disclosing behavior. It does mention costs and asynchronous minting, which is valuable. However, it leaves 'Confirm (yes/no)' ambiguous—there is no corresponding parameter in the schema—and does not explain side effects, reversibility, or what the returned JSON contains. It is a moderate disclosure but incomplete.

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 somewhat concise but contains a redundant first sentence repeated almost verbatim twice. The structure with @param lines is clear, but the duplication wastes space and adds no value. The 'Confirm (yes/no)' line is also not well-integrated, making the beginning clunky.

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?

The tool has 5 parameters, an output schema, and no annotations. The description covers costs and async, but omits important operational details such as how confirmation is performed, possible errors, and what the JSON return actually contains. The output schema exists but cannot be seen by the agent from the description alone; the '@return: a json object' is insufficient. Overall, it is not fully complete for an operation of this complexity.

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 @param lines in the description are the only source of parameter meaning. They add context for all five parameters: source of api_key, token, wallet_fk, account_type_fk (with reference to /account/types and default 7), and currency_fk (with reference to /currency/list and default 7). This fully compensates for the absent schema descriptions and gives the agent actionable details.

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 a specific action: "Mints a new account of an account type into the wallet." The verb "mint" is unique among sibling tools and distinguishes this from other account operations like buy, sell, send, or charge. It also specifies the resource (account) and target (wallet).

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?

No explicit guidance is given on when to use this tool instead of alternatives. It mentions costs and asynchronous behavior but does not compare with other account creation or wallet-related tools. The phrase 'Confirm (yes/no) before executing' hints at a usage step but is not elaborated and does not clarify selection criteria.

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