Deactivate Purchase Option Offer

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

With no annotations provided, the description carries the full behavioral burden. It does disclose the core effect on new buyers and notes the read-only-mode restriction, but it omits whether the action is reversible, what permissions are required, and how this differs from canceling an offer.

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 two short sentences, with the action and effect front-loaded and a necessary execution caveat following it. There is no redundant or filler text.

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 four-parameter mutation tool with full schema descriptions and an output schema, the description is mostly adequate for direct invocation. It is incomplete mainly in not guiding the agent away from similar sibling tools and not clarifying side effects beyond new-buyer availability.

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 100%, so the description does not need to compensate for undocumented parameters. It adds no parameter-specific meaning beyond what the input schema already provides, so the high-coverage baseline of 3 is appropriate.

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 names the verb (deactivate), the resource (one-time product offer), and the intended effect (making it unavailable to new buyers). However, it does not explicitly distinguish this from sibling tools like activate_purchase_option_offer or cancel_purchase_option_offer, so it falls short of a 5.

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?

There is no guidance about when to choose this tool over alternatives such as activate_purchase_option_offer, cancel_purchase_option_offer, or batch state update tools. The read-only-mode caveat is a constraint, but it does not help the agent select among related offer-management tools.

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