xero_create_tracking_option

DestructiveIdempotent

Create a new tracking option in Xero to categorize transactions by custom fields such as projects, departments, or locations for detailed reporting.

Instructions

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

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

C2.4/5.0
Behavior3/5

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

Annotations already flag destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the bar for additional behavioral disclosure is lower. The description adds some context around governed routing, effect verification, and the approval_ref resume mechanism for writes, which is useful. However, it never states what side effects the operation has on Xero data.

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

Conciseness4/5

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

The description is short, organized as a routing note and a clean parameter bullet list. It avoids excessive prose, though the opening sentence is largely redundant with the tool name.

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?

For a create operation with 7 parameters, no schema descriptions, and a core arguments payload, the description is materially incomplete. The output schema exists but does not compensate for the absence of domain behavior, required argument fields, and relationship to tracking categories.

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

Parameters2/5

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 the parameter documentation burden. It gives terse labels for plumbing parameters (project_id, project_ref, connector_account_ref) but leaves the critical 'arguments' parameter as an opaque 'JSON string of arguments for the connector operation.' An agent cannot know what fields to place in the arguments JSON to create a tracking option.

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 ('Xero connector operation create_tracking_option') without explaining what a tracking option is or what creating one does in Xero. The routing sentence adds authority context but not domain purpose. An agent cannot tell from the description what business object this tool creates.

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 guidance on when to use this tool versus alternatives like xero_create_tracking_category or xero_update_tracking_options. The only usage-related statement is about routing through governed connector authority, which is a constraint rather than a selection criterion.

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