create_custom_product_page

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

No annotations are supplied, and the description only states 'Create' without disclosing permission requirements, whether the page is immediately live, how to handle errors, or what the return value is. This is minimal behavioral information.

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, focused sentence with no redundant words. It conveys the essential purpose directly, though it lacks elaboration.

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 simple create tool with two parameters, the description is adequate but not comprehensive. It lacks information about prerequisites, consequences (e.g., does it require localization?), or what the created page looks like. No output schema or annotations exist to supplement.

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 100%, with both parameters (name, appId) described in the schema. The tool description does not add additional parameter context, so the baseline of 3 applies.

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), the resource (custom product page), and the scope (for an app). It distinguishes from sibling tools like update_custom_product_page and list_custom_product_pages by using the create verb.

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 usage guidance is provided. The description does not explain when to use this tool instead of create_iap or create_subscription_group, nor does it mention any prerequisites or alternative tools.

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