end_app_availability_pre_orders__create

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

Annotations indicate it's not read-only, not idempotent, not destructive, but the description adds no behavioral context beyond 'create'. No mention of side effects, authorization, or rate limits.

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 short and gets straight to the point. However, it could benefit from a bit more structure, such as mentioning required relationships or the purpose of the pre-order.

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?

Lacks details about return values (no output schema), no explanation of the concept of end app availability preorders, and no differentiation from related tools. For a complex nested schema, more context would help an agent.

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 schema has 100% coverage with a generic description for the body parameter, but the tool description does not add any meaning about what the body should contain or how parameters are used. It relies entirely on the 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 clearly states the action ('Create') and the resource ('end app availability pre order'), and includes the HTTP endpoint. It distinguishes itself from sibling tools, which cover different resources like app_clip_advanced_experiences__create or beta_groups__create.

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 on when to use this tool vs alternatives (e.g., app_availabilities_v2__create). No prerequisites, context, or exclusions provided.

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