setup_virtual_account

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

No annotations provided, so description bears full burden. It discloses that the tool creates a virtual account and auto-converts deposits, but does not mention side effects (e.g., whether customer must exist, or if it's idempotent) or permission requirements.

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?

Description is a single dense paragraph, but front-loaded with purpose and efficient. Could be improved with bullet points for parameter values, but overall concise without waste.

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 creation tool with 6 parameters and an output schema, description covers purpose, parameter meanings, and key behavior. Does not repeat return values (covered by output schema), making it adequate.

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%, so description explains 5 of 6 parameters with example values (e.g., 'usd'/'eur', 'sol'/'ethereum'). Customer_id is mentioned only as required but not explained. Integral default is clarified.

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?

Description clearly states verb 'Create' and resource 'virtual account' for automatic fiat-to-stablecoin conversion. It distinguishes from sibling tools like 'get_virtual_account' or 'list_virtual_accounts' by specifying the exact conversion purpose.

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?

Description implies usage context (fiat-to-stablecoin conversion) but does not explicitly state when not to use or provide alternatives. It gives example values for currency and network, aiding selection, but lacks explicit guidance.

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