create_inventory_transfer

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the creation of a transfer and does not mention side effects, permissions, reversibility, or what the response contains. For a mutation tool, this is a significant gap, similar to the update_drive calibration example.

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 a single clean sentence with no redundant words. It communicates the action, resource, and context efficiently, earning every word.

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?

The tool is relatively simple with three fully documented parameters and no output schema. The description is sufficient for basic usage but could benefit from noting whether inventory levels are affected immediately or if this is just a pending transfer record, especially given the absence of annotations.

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 provides 100% coverage with descriptions for all three required parameters, so the baseline is 3. The description adds no additional parameter semantics beyond the schema's existing originLocationId, destinationLocationId, and lineItems definitions.

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 uses a specific verb ('Create') and identifies the exact resource ('inventory transfer') along with the scope ('between locations'). It clearly distinguishes from sibling tools like get_inventory_transfer or receive_inventory_transfer, as this is the creation action.

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 creating a transfer between locations but does not explicitly state when to use this tool versus alternatives such as receive_inventory_transfer or get_inventory_transfer. No exclusions or alternative guidance is provided, but the context is understandable from the name.

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