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

The description mentions the return of an updated order summary but does not disclose side effects like irreversibility or potential error conditions. With no annotations provided, this lack of detail limits the agent's understanding of the tool's full behavioral impact.

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 concise, consisting of two short sentences that convey the core action and the return value without any extraneous information. It is well-structured and easy to parse.

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?

The description provides the essential context of what the tool does and what it returns, which is sufficient for most use cases. It lacks details on error handling or preconditions, but given the simple nature of the operation, it is reasonably complete.

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?

The schema descriptions already cover all parameters with clear meaning, and the description adds only the word 'optionally' for the notify_customer parameter, which is minimal. Since schema coverage is 100%, this baseline score reflects that the description does not significantly enhance parameter understanding.

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 tool's action with a specific verb 'cancel' and identifies the resource 'order'. It also notes the optional email action, which distinguishes it from other order-related tools like fulfilling or listing orders.

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 when an order needs to be cancelled, but it does not explicitly contrast with alternatives such as fulfilling or updating an order. However, the purpose is straightforward and unambiguous enough for an agent to decide when to invoke it.

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