apple_get_custom_product_page

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

No annotations are provided, so the description carries the full burden, yet it discloses almost no behavioral traits: no indication of whether versions are returned in full or as references, no behavior when pageId is invalid or the page is unpublished, no auth or permission notes, no pagination hints.

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 short sentence, front-loaded with the verb and resource, with no filler. It is efficiently written but so terse that the brevity reflects under-specification as much as conciseness.

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?

With no annotations, no output schema, and an undocumented required parameter, the description leaves key questions unanswered: what fields the page and its versions contain, whether a missing id errors or returns empty, and how this differs from the version-listing tool.

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 single parameter pageId has no description in the schema or in the tool description. The only clue is the parameter name itself, so the description adds essentially nothing to the parameter's meaning or expected format.

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 ('Get a custom product page') and adds a useful scope note that the returned page includes its versions. It is distinguishable from apple_list_custom_product_pages and apple_update_custom_product_page by name, though it never explicitly contrasts itself with those siblings.

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 guidance on when to use this versus apple_list_custom_product_pages or apple_list_custom_product_page_versions. The agent must infer from the name alone that this is a single-item fetch by id.

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