create_event_inventory_tier

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It merely restates the creation action and does not mention effects such as capacity counting, defaulting of count_against_event_capacity, idempotency, or what the created tier looks like in the response. The description adds no behavioral transparency beyond the tool name.

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 compact sentence with no filler and the core action is front-loaded. It is appropriately brief, though the brevity borders on under-specification.

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 creation tool with four parameters and no annotations, the description is too thin to be fully self-sufficient. The presence of an output schema covers return shape, but parameter semantics and usage context are not supplied. An agent would still need to infer key details about the tier's purpose and required inputs.

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%, and the description does not explain any of the four parameters. It does not clarify how quantity_total is used or what count_against_event_capacity means beyond its schema default. The description adds no value beyond the parameter names already visible in the input schema.

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 ('Create a new') and a resource ('inventory tier for an event'), and the verb alone distinguishes it from sibling tools like update_event_inventory_tier, delete_event_inventory_tier, and list_event_inventory_tiers. The purpose is unmistakable and correctly scoped.

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?

There is no explicit 'use when' or 'use instead' guidance, so an agent must infer when to call this tool from the verb and the sibling names. It is implied that this tool is for creating rather than updating or deleting a tier, but no context is given about when such a tier should be created.

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