bulk_create_items

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

With no annotations, the description carries the full disclosure burden. It usefully states the batch limit of 20, the expected item shape, and supported types, but it does not mention permissions, atomicity/partial-failure behavior, or other operational constraints for this write 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?

The description is front-loaded with the core action and limit, then supplies the payload shape and type list without unnecessary prose. The compact JSON example earns its place by clarifying the otherwise undocumented `items` schema.

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?

For a two-parameter bulk-create tool with an output schema, the description provides enough payload detail to invoke it correctly. It is slightly incomplete on `board_id` semantics and operational behavior, but the core invocation requirements are covered.

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 0%, so the description must compensate. It does this well for the complex `items` parameter by showing the entry shape and supported types, though it does not explain the required `board_id` parameter beyond its name.

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 states a specific verb and resource ('Create ... items') and adds the bulk scope ('up to 20 items in one call'), which distinguishes it from the singular create_* siblings. It also names the supported item types, making the tool's scope clear without opening the schema.

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 bulk framing and 'up to 20 items in one call' imply when to use this instead of individual creators, but there is no explicit guidance naming alternatives or stating when not to use it. Usage is inferable but not fully spelled out.

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