Subscriptions_CancelaSubscripti

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

No annotations are provided, and the description does not disclose behavioral traits such as destructive effects, required permissions, or side effects. The agent receives no information about whether the cancellation is reversible, what happens to related items, or if confirmation is needed.

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 a single sentence, which is concise and front-loaded. However, it is overly minimal and does not provide additional context beyond the tool name, meaning it does not fully earn its place by adding value.

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?

Despite the tool's simplicity (no parameters, no annotations), the description lacks completeness. It does not explain the return value or confirm the action. Without an output schema, the agent is left guessing about the response format or success indicators.

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 input schema has no parameters, so the description does not need to explain parameters. The schema coverage is 100% (empty), meaning the description adds no parameter semantics, but this is acceptable given the absence of parameters.

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 'Cancel a Subscription' explicitly states the verb (cancel) and resource (subscription), clearly indicating the tool's purpose. However, it closely mirrors the tool name 'Subscriptions_CancelaSubscripti', adding minimal additional clarity. It distinguishes from siblings like 'Subscriptions_Updateasubscripti' and 'Subscriptions_Retrieveasubscrip' but offers no further detail.

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 provides no guidance on when to use this tool versus alternatives such as updating a subscription or other cancellation operations like 'cancelCharge'. There are no suggestions, prerequisites, or exclusions.

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