quickbooks_pay_bill

DestructiveIdempotent

Pay outstanding bills in QuickBooks through a governed connector. Uses idempotency and approval checks to ensure accurate, controlled accounts payable processing.

Instructions

Quickbooks connector operation pay_bill (platform tool quickbooks.pay_bill).

Routes only through the exact project/account governed connector authority.

Args: arguments: JSON string of arguments for the connector operation. project_id: Authenticated Project UUID. project_ref: Exact project correlation reference. connector_account_ref: Project-bound connector account alias. idempotency_key: Stable business-action identity. effect: Claimed read or write effect; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

C2.8/5.0
Behavior4/5

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

Annotations already convey read/write/idempotent/destructive traits, and the description adds meaningful context: the operation routes only through a governed connector authority, effect is declared and verified by the platform, and approval_ref is required when resuming a write. It also identifies idempotency_key as a stable business-action identity, complementing the idempotentHint annotation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The Args list is compact and readable, but the opening sentence redundantly restates the tool name and platform path. The description is not bloated, yet the first sentence adds little information beyond the tool name itself.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite annotations and an output schema, the description omits the core domain semantics needed to invoke the operation correctly: what arguments the arguments JSON expects, prerequisites such as an existing bill/vendor, and the effect a successful pay_bill has on QuickBooks records. The approval/governance scaffolding is present, but the domain payload contract is absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry parameter meaning, and it does for all seven parameters. Each arg has a one-line explanation; however 'arguments: JSON string of arguments for the connector operation' is generic and does not reveal what the QuickBooks pay_bill payload should contain.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description restates the tool name as 'Quickbooks connector operation pay_bill' and its platform identifier, but never states what paying a bill accomplishes or what domain action is performed. Without the self-explanatory name, an agent would not know this records a payment against a QuickBooks bill.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use or when-not-to-use guidance, and no comparison to alternative tools such as quickbooks_list_bills, quickbooks_create_bill, or xero_pay_bill. The only contextual guidance is the governance routing constraint and approval_ref for resuming writes, which is operational detail rather than selection guidance.

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