qbo_transfers_update

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

Without annotations, the description discloses the sparse-update behavior and required fields (Id and SyncToken). However, it omits details on authorization, rate limits, concurrency handling, or potential side effects. The behavioral disclosure is adequate but not comprehensive.

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

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

The description is exceptionally concise with only two sentences, each delivering essential information. The key concept 'sparse-update' is front-loaded, and there is no redundant or extraneous wording.

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

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

Given no annotations, no output schema, and 7 parameters including nested objects, the description covers the core sparse-update concept and required fields. However, it lacks details on return format, error handling, or prerequisites, making it somewhat incomplete for a tool of this complexity.

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

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

The input schema has 100% coverage with descriptions for all parameters, so the baseline is 3. The description adds a high-level explanation of sparse update and reiterates the requirement for transferId and SyncToken, but does not add new semantic meaning beyond the schema's existing descriptions.

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

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

The description clearly states the action 'sparse-update' and the resource 'existing Transfer record', effectively distinguishing it from related tools like qbo_transfers_create (which creates). It specifies that only provided fields are changed, solidifying the purpose.

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

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

The description implies usage for partial updates ('Only provided fields are changed') but does not explicitly state when to use this versus alternatives like create or full update. No direct 'use when' or 'do not use' guidance is provided, leaving some ambiguity.

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