unsubscribe_notification

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'Unsubscribe from a notification', which implies a state change but fails to explain effects (e.g., idempotency, confirmation side effects, authentication needs). The description is too minimal for an agent to understand implications.

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 short sentence with no redundant information. It is front-loaded with the verb and resource. However, it could include more detail without being verbose, so it scores high but not perfect.

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?

Given the lack of output schema, no behavioral annotations, and a nested input object, the description should provide more context about return values, prerequisites, and the optional email parameter. It only covers the basic action, leaving significant gaps for agent understanding.

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 descriptions for 'id' and 'email' sub-properties, but the top-level 'input' parameter has no description. The tool description only mentions 'by ID', adding no extra meaning beyond the schema. The optional 'email' parameter is not referenced, so the description does not compensate for the 0% schema description coverage at the top level.

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 verb 'unsubscribe' and the resource 'notification by ID'. It distinguishes this tool from siblings like 'unsubscribe_notification_global' (which unsubscribes from all notifications) and 'undo_notification_unsubscribe' (which reverses), making it clear that this tool targets a specific notification by ID.

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 vs alternatives. Siblings like 'undo_notification_unsubscribe' and 'unsubscribe_notification_global' exist, but there is no mention of appropriate contexts or exclusions.

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