xero_create_history_note

DestructiveIdempotent

Create a history note in Xero for a project-bound connector account, enforcing idempotency and approval for governed write operations.

Instructions

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

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.

C2.6/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=true, so the description does not need to restate them. It does add useful operational context: authority routing, a claimed read/write effect verified by Spring, and an approval_ref requirement when resuming a write. However, it does not describe actual side effects or what destructive behavior may occur, so it adds only partial behavioral clarity.

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 compact, uses a clean argument list, and does not pad itself with fluff. The first line is somewhat redundant with the tool name, but the rest of the content is tightly structured and easy to scan.

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 write-capable connector tool with zero schema parameter descriptions, the definition is incomplete: it never explains what Xero history-note creation means, what fields the `arguments` JSON must contain, or how the operation behaves from the Xero domain's perspective. The output schema exists and annotations are rich, but the agent still cannot determine the actual payload needed to invoke this tool correctly.

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

Parameters3/5

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

Schema description coverage is 0%, so the description must compensate, and it does label all seven parameters with semi-meaningful descriptions. Yet the most important parameter, `arguments`, is only explained as 'JSON string of arguments for the connector operation,' which is self-referential and gives no concrete shape for creating a history note. The other parameter labels add value but remain high-level.

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 mostly restates the tool name as 'Xero connector operation create_history_note' and its platform alias, which is close to tautology. It does not say what creating a history note actually does in Xero, what resource it applies to, or how it differs from the many sibling xero_create_* / xero_list_history operations.

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?

The only guidance is 'Routes only through the exact project/account governed connector authority,' which is an invocation constraint, not a usage guideline. There is no statement of when to prefer this tool over alternatives, no exclusions, and no contextual trigger for calling it.

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