apple_create_custom_product_page_version

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

No annotations are provided, so the description carries the full burden. It does convey the resulting state ('new editable version'), but says nothing about whether existing content is copied, whether a prior draft blocks creation, permission requirements, or side effects on the live approved version.

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?

A single front-loaded sentence with no filler. It is efficient, though its brevity is also the source of the missing detail rather than a deliberate trade-off.

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 mutation tool with no annotations, no output schema, and 0% parameter coverage, the description does too little. An agent cannot tell what the call returns (presumably a new version ID), how to use deepLink, or what to do next after the version is created.

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 mentions neither parameter. 'pageId' is at least inferable from 'custom product page', but 'deepLink' (a URI-formatted string) is completely unexplained — its purpose, format, and whether it is optional are left entirely to guesswork.

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 ('Start a new editable version') against a specific resource ('an approved custom product page'), so an agent knows this creates a new draft version rather than modifying an existing one. It does not explicitly name sibling tools like apple_update_custom_product_page_version or apple_create_custom_product_page, so differentiation is left to inference.

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?

'of an approved custom product page' implies the precondition that a page must already be approved before a new version can be started, which is useful context. However, it never states when to choose this over apple_update_custom_product_page_version or apple_create_custom_product_page, nor what to do when a draft version already exists.

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