create_item

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

No annotations are provided, so the description must carry the full burden of disclosing behavioral traits. It only states 'Create' with no mention of side effects, required permissions, idempotency, or return behavior. For a mutation tool, this lack of transparency is a significant gap.

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 sentence with no filler or redundant phrasing. It is appropriately brief and front-loaded with the core action.

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 a mutation tool with a nested object parameter and no output schema, the description is insufficient. It does not explain what the tool returns, what fields are required in 'item_data', or how the resource parameter maps to actual Business Central entities. Sibling tools like get_schema may be needed to understand usage, but the description should provide more context.

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?

Schema description coverage is 100%, and both parameters have descriptions in the schema. The tool description adds no extra meaning beyond the schema, so it meets the baseline. The nested object parameter 'item_data' is unclear, but the schema already covers 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 uses a specific verb ('Create') and a resource ('item') with a clear scope ('in Business Central'), which clearly distinguishes it from sibling tools like update_item, delete_item, and list_items. The purpose is immediately unambiguous.

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 items, but it does not explicitly state when to use this tool versus alternatives, nor does it mention exclusions or prerequisites. It is a one-line statement with no guidance on distinguishing from update/delete scenarios.

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