create_payment_method

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

No annotations are supplied, so the description carries the full behavioral burden, yet it only implies a mutation via the verb 'Create'. It does not disclose permission/auth requirements, duplicate-name handling, whether a created method can be deleted, or anything about the response body. For a write tool with zero annotation coverage this is a substantial gap.

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?

One short sentence with the verb and resource front-loaded and no filler. The parenthetical examples are the only arguable padding, and they are at least short.

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?

A create/mutation tool with no annotations, no output schema, a nested parameter object, and no explanation of the type enum or return behavior. An agent could call it but could not predict side effects, duplicate handling, or what comes back.

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% and the single parameter is a nested object, so the description must compensate. The examples ('Cash, Check, Credit Card') usefully signal that `name` is a free-text label rather than an enum value, but they do nothing to explain the `type` field's CREDIT_CARD/NON_CREDIT_CARD enum or its relationship to the name, and could even mislead an agent into treating 'Credit Card' as a type.

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 ('Create a new payment method') and scopes it to QuickBooks Online, which separates it from the many create_* transaction siblings like create_payment and create_bill_payment. It stops short of naming the reference-data siblings (get_payment_method, update_payment_method, search_payment_methods) but the entity is unambiguous.

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?

There is no when-to-use guidance: nothing says whether this is reference data that should exist before creating payments/invoices, what to do if a method with the same name already exists, or how it differs from the search/update siblings. The agent is left to infer usage entirely from the name.

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