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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing beyond the operation itself. It does not state that deletion is irreversible, what happens if the id does not exist, whether it fails silently, or what permissions are required — key omissions for a destructive operation.

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?

A single front-loaded sentence with zero filler; the operation and selector come first. Nothing is wasted, though there is also very little content.

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 destructive one-parameter tool with no annotations and no output schema, the description is too thin: irreversibility, failure behavior on unknown ids, and auth expectations are all unstated. The rich schema on the single parameter partly compensates, but the mutating semantics are not covered.

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%, and the schema already specifies the parameter as a "UUID from list_notifications," so the baseline is 3. The description's "by id" adds nothing beyond what the schema field already documents.

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 gives a specific verb ("Remove") and resource ("notification subscription") and indicates the selector ("by id"), so the agent knows exactly what operation it performs. It does not explicitly name its siblings (create_notification, list_notifications), so differentiation is inferable rather than stated.

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 on when to use this versus alternatives such as create_notification or list_notifications, nor any prerequisite or precondition (e.g. needing the subscription to exist). The agent must infer usage entirely from the tool name.

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