set_iap_price

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 indicates a write operation via 'set or update' but does not disclose side effects, reversibility, authorization requirements, or behavior on failure. Lacks behavioral detail beyond the mutation itself.

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?

Single sentence, front-loaded with the action, and contains no filler words. The mention of 'price point ID' is relevant and concise.

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 two-parameter setter, the description provides the essential information: what action is performed and the key input. However, it lacks context about validation, whether the price is immediately effective, or how to discover price points (though the schema mentions the API). It is adequate but not rich.

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 descriptions for both iapId and pricePointId, so the schema carries the parameter meaning. The description reinforces the role of pricePointId but adds no new details beyond what the schema already states.

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 ('set or update'), the target resource ('in-app purchase'), and the specific aspect ('price'). It also specifies the mechanism ('using a price point ID'), distinguishing it from sibling tools like update_iap and set_subscription_price.

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 description implies usage for changing IAP pricing but provides no explicit guidance on when to use this tool versus alternatives such as update_iap or set_subscription_price. There is no mention of prerequisites like listing price points first (though that is in the schema) or exclusions.

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