create_item

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

With no annotations provided, the description carries the full burden for behavioral disclosure, but it only states the action without any side effects, permission requirements, or consequences. There is no mention of what happens on success, whether the operation is irreversible, or any rate limits. The description adds zero behavioral context beyond the obvious mutation implied by 'create'.

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 clear sentence with no wasted words. It is appropriately front-loaded with the action. However, it is so terse that it omits critical context, but that is a completeness issue rather than a conciseness failure.

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 the absence of an output schema and annotations, the description should explain how to use the resource and item_data parameters, but it does not. The nested object item_data is undefined, and the agent must guess what fields to provide. The existence of sibling get_schema tool could mitigate this, but the description itself is incomplete for a create operation with a flexible resource parameter.

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% description coverage, so both parameters (resource and item_data) are already documented. The description adds no additional meaning about parameter values, format, or relationships. Baseline 3 is appropriate because the schema does the heavy lifting, and the description does not contradict or enrich it.

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 'Create a new item in Business Central' clearly states the verb (create) and resource (item), distinguishing it from update/delete/list siblings. It is slightly tautological with the tool name but adds the Business Central context. No ambiguity about the operation's intent.

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?

No guidance is given on when to use this tool versus alternatives like update_item or delete_item. The usage is only implied by the name 'create_item', but there is no explicit context about prerequisites or decision criteria. The sibling tools are listed but not referenced in the description.

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