xero_list_statements

Read-onlyIdempotent

Fetch Xero bank statements for an approved read operation. Returns statement records tied to the governed project account to support reconciliation and review.

Instructions

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

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: Required and must be read; Spring verifies it. approval_ref: Approved platform task UUID when resuming a write.

TDQS

D1.7/5.0
Behavior2/5

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

The annotations indicate readOnlyHint and openWorldHint, but the description does not mention that this operation is read-only or non-destructive. It also fails to describe return format, pagination, or any side effects beyond the generic 'routes through connector authority' boilerplate.

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 description is short and not verbose, but it is repetitive boilerplate that likely appears verbatim across many unrelated tools. It does not efficiently convey tool-specific information, so while concise in word count, it is not concise in meaning.

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?

For a connector operation that lists statements, critical context is missing: what a 'statement' refers to (bank statement, financial statement?), what filters or inputs are supported, what the response schema looks like, and how it differs from sibling tools. There is no output schema description either, despite one being present in the system, leaving the agent completely uninformed.

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?

The input schema has no descriptions for any parameter. The 'arguments' field is a generic JSON string with no indication of what properties are expected (e.g., account ID, date range, status filters). The required 'effect' parameter is constrained to 'read' but its purpose is not explained. Schema coverage is 0%, and the description adds no value.

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 names the operation 'list_statements' but provides no specifics about what statements are being listed, in what context, or what the output represents. It is essentially a placeholder that repeats the tool name without adding meaningful purpose.

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?

There is no guidance on when to use this tool versus other Xero listing tools (e.g., xero_list_invoices, xero_list_bank_transactions). No prerequisites, scenarios, or examples are provided.

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