apple_set_review_details

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

With no annotations, the description carries the full burden and does well: it declares "External action" (a remote mutation), discloses partial-update semantics ("Only the fields passed are changed"), and reveals a hidden side effect ("Passing demo_account_name turns on demoAccountRequired automatically"). It stops short of stating auth/permission requirements or reversibility.

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?

Purpose and the key constraint (partial update) are front-loaded. The subscription-app rationale is somewhat digressive but genuinely instructive, so it earns most of its space.

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?

An output schema exists, so return values need not be described. The description covers the mutation's key behavioral traits and the demo-account workflow, though the unexplained contact/notes parameters and unstated auth requirements leave modest gaps.

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 0% across 8 params, so the description must compensate. It explains the demo_account fields' purpose and the demoAccountRequired side effect well, but says nothing about notes, contact_email, contact_phone, or contact_first/last_name semantics, leaving half the surface undocumented.

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 and resource: filling in App Review contact/demo-account details before testing. An agent can tell it apart from listing or submission siblings like apple_review_details and apple_submit_for_review, though it never explicitly names 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?

Provides conditional context ("when the app has content behind a login" the demo account must reach the purchase flow), which is genuine usage guidance. However, there is no explicit when-to-use-this-vs-alternatives statement, e.g. versus apple_set_app_info or apple_review_details.

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