Post Instances Customers Bank Accounts Offramp Wallets

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

The annotations already indicate this is a non-read-only, non-destructive, open-world operation, but the description adds no behavioral context beyond the bare action. It does not explain what the created offramp wallet represents, how it relates to the bank account, or any permission or side-effect considerations.

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 three-word phrase with no wasted text, but it is under-specified rather than appropriately concise for a mutation endpoint with five parameters. It front-loads the action but omits all necessary context.

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's complexity, nested request body, low schema description coverage, and lack of an output schema, the description is far too thin. An agent cannot determine required setup, parameter meaning, or expected outcome from 'Create Offramp Wallet' alone.

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 only 40%, so the description needs to compensate, but it provides no parameter information at all. Required fields such as instance_id, bank_account_id, and requestBody.network are not explained, and the nested request body is left entirely to the schema.

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 states a specific verb and resource: 'Create Offramp Wallet'. This is clearer than a tautology, but it does not distinguish the operation from sibling wallet-creation or bank-account-related endpoints.

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 provides no guidance on when to use this tool instead of alternatives such as PostV1InstancesCustomersBankAccounts or other wallet creation endpoints. It also omits prerequisites, such as needing an existing customer and bank account.

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