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 discloses that a created page is a draft, starts from live version media, keywords must already be approved, search visibility occurs after approval, and the founder submits for review. However, it omits permissions required, rate limits, what 'list' returns, and side effects of creation beyond draft status.

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 single run-on sentence packs a lot of information but is awkward and not front-loaded; readers must parse multiple clauses to find the core action. It is efficient in length but weak in structure.

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?

Given 8 parameters, no required fields, no output schema, and no annotations, the description is partially complete: it clarifies draft creation, key constraints, and the ppid/app_site link. It still leaves significant gaps around listing behavior, parameter roles, and operational requirements.

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 only 25%, so the description must compensate. It adds meaning to keywords (approved-only, search after approval) and screenshots (captioned, from live media) and mentions ppid linkage, but does not explain name, appId, locale, deepLink, or action semantics. Partial compensation warrants a middle score.

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 dual action (list or create a draft custom product page) and enumerates the created artifacts (promotional text, deep link, keywords, captioned screenshots). It is specific but does not explicitly differentiate itself from siblings like app_metadata, app_screenshots, or app_site, other than mentioning ppid linkage.

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 explicit guidance on when to use this tool versus alternatives. The mention that the founder submits for review in App Store Connect and that linking uses app_site is contextual, but there are no when/when-not conditions or named alternatives for the core list/create decision.

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