bulk_create_items

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

With no annotations provided, the description carries full burden. It details required item fields but omits behavioral traits: partial failure behavior, authentication needs, rate limits, idempotency, or transaction guarantees. This gap is critical for a bulk operation.

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?

Two concise sentences: first states purpose, second details item structure. No extraneous text, information is front-loaded and easy to parse.

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 description does not mention return values, error responses, or constraints (e.g., maximum items per call). Given the complexity of bulk creation and lack of annotations/output schema, this leaves significant gaps in understanding the tool's full behavior.

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 coverage is 0%, and the description adds significant value by explaining that 'items' is an array of objects with required keys ('code', 'name', 'unit') and optional ones, and that 'section_id' applies to all. This compensates for the schema's minimal definition (additionalProperties: true).

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 'Create many items under one section in a single call,' distinguishing it from the sibling tool 'create_item' which creates single items. The verb 'create' and resource 'items' are specific, and the scope ('many,' 'under one section') is explicit.

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 batch usage via 'many items' and 'single call,' but does not explicitly state when to use this tool versus alternatives like 'create_item' for single inserts or other batch methods. No exclusions or prerequisites are mentioned.

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