submit_iap_for_review

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the agent knows this is an irreversible external mutation. The description adds only the 'independent of app version' scope note and says nothing about side effects such as the IAP becoming locked from edits while in review or the failure mode on duplicate submission, which would be the valuable extra context given destructive/non-idempotent flags.

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?

One front-loaded sentence with the differentiator at the end; nothing redundant and nothing that could be cut.

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 single-parameter mutation with fully documented schema and annotations covering safety and idempotency, the description covers the essential purpose and scope. It could be slightly more complete about post-submission state changes, but there is no major gap.

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?

Only one parameter and schema coverage is 100%, with the schema documenting iapId as 'The in-app purchase ID'. The description adds no format, source, or lookup guidance, so baseline 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?

States a specific verb (submit) and resource (in-app purchase) plus a scope qualifier ('independently of the app version') that separates it from the sibling submit_for_review, which presumably submits the app version itself. An agent can pick this over submit_for_review and submit_beta_review without opening a schema, though the differentiation is implied rather than stated by name.

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?

The phrase 'independently of the app version' hints at the use case (IAP review that isn't tied to an app version submission), but it never says when to choose this over submit_for_review, nor what prerequisites exist (e.g., IAP must be in a ready state, no pending review).

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