apple_create_custom_product_page

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

With no annotations, the description carries the full burden. It discloses the useful atomic behavior (page + first version + localizations created together) and that copying is optional. It does not state the resulting state of the page (draft vs. live), permission requirements, or failure behavior for a mutation that creates several resources.

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?

Three short sentences, each earning its place: purpose, optional behavior, follow-up workflow. The core capability is front-loaded with zero preamble.

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 multi-resource mutation with no annotations and no output schema, the description covers what gets created, the optional copy sources, and the follow-up path. It omits the resulting page state, permissions, and what the caller gets back, which an agent would want before invoking.

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 50%: deepLink, locale, and both template params are documented in the schema. The description adds meaning for the two template IDs by framing them as an optional copy source. But the required name and appId parameters are undocumented in both places, so it only partially compensates.

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?

States a specific verb (create) and resource (custom product page) plus the key scope detail that it also creates the first version and localizations in one request. That 'in one request' phrasing implicitly separates it from the granular sibling tools like apple_create_custom_product_page_version and apple_create_custom_product_page_localization. It isn't explicit about sibling distinction, keeping it at 4.

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?

Explains the conditional use of the template parameters ('optionally copy screenshots and text from an App Store version or another custom page') and gives a workflow pointer ('add visuals afterwards with the Asset Library placement tools'). It lacks an explicit 'use this instead of X when...' exclusion, but the context is clear.

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