xero_update_receipt

DestructiveIdempotent

Update an existing Xero receipt through a governed connector account, using authenticated project credentials and idempotency key to ensure accurate, repeatable write operations.

Instructions

Xero connector operation update_receipt (platform tool xero.update_receipt).

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

C2/5.0
Behavior3/5

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

The annotations already disclose destructive and idempotent behavior, satisfying the baseline. The description adds a routing constraint ('Routes only through the exact project/account governed connector authority') but does not describe any side effects or what changes are made to the receipt. Since annotations cover the key traits, this is adequate but not enhanced.

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

Conciseness2/5

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

The description is brief but repetitive, with each parameter explanation merely restating the parameter name in a generic way. It is not well-structured for quick reference, as the parameter list lacks meaningful details and the opening sentence adds no actionable information beyond the tool name.

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

Completeness1/5

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

The description omits essential context about the receipt update operation, such as the expected structure of the arguments, required fields, how the update interacts with Xero data, or what the response contains. Despite having an output schema, it is not referenced, leaving the tool's behavior largely unspecified.

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

Parameters1/5

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

None of the seven parameters have schema descriptions, and the description's own explanations are generic boilerplate (e.g., 'JSON string of arguments for the connector operation'). There is no indication of what fields must be included in the 'arguments' JSON to update a receipt, making it nearly impossible to construct a valid call.

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

Purpose3/5

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

The description clearly identifies the tool as an operation to update a receipt in Xero, and the name itself conveys the primary purpose. However, it lacks any detail about what updating a receipt entails or how it differs from creating a receipt, so it only partially distinguishes from sibling tools.

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

Usage Guidelines1/5

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 versus alternatives like xero_create_receipt or xero_list_receipts. There is no mention of prerequisites, conditions, or typical scenarios, leaving the agent without any usage direction.

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