quickbooks_list_departments

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

Annotations already provide readOnly, idempotent, and non-destructive behavior; the description adds that effect must be 'read' and is verified by Spring and that routing goes through the project/account connector authority. The 'approval_ref ... when resuming a write' line is confusing on a read-only tool, but it is not a direct contradiction of the readOnlyHint.

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 compact and front-loaded: operation identity, routing constraint, then a tidy Args list. It is mostly free of fluff, though a couple of the parameter explanations are generic boilerplate.

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?

Output schema and annotations cover return shape and safety, and the parameter list is present. Still, the description is generic for a connector wrapper: it does not say what arguments may contain for list_departments and never clarifies the intended use of approval_ref on a read-only list. It is workable but not complete enough for all practical invocation questions.

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?

With 0% schema description coverage, the description compensates by enumerating and glossing all seven parameters, including project_id as an authenticated UUID, connector_account_ref as a project-bound alias, and idempotency_key as a stable business-action identity. However, the central arguments parameter is still only described generically as 'JSON string of arguments for the connector operation,' so it does not deserve a 5.

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 names the operation and resource ('Quickbooks connector operation list_departments') and gives the platform-level tool id, so an agent can tell it lists QuickBooks departments. It stops short of a plain behavioral sentence like 'Lists all departments in QuickBooks' and does not explicitly differentiate from sibling QuickBooks list tools beyond the resource name.

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 guidance about when to use this tool instead of other QuickBooks list operations, no exclusions, and no alternatives. The only contextual line is about routing through the governed connector authority, which is an invocation constraint rather than a usage decision.

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