Verify Notification Delivery

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

Annotations already indicate readOnlyHint=false, openWorldHint=true, and idempotentHint=false. The description adds useful behavioral context beyond this: the operation is harmless, runs server-side, and involves sending then polling back. It also discloses a permission requirement, which helps the agent anticipate invocation failures.

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?

Two concise sentences with no filler. The core action is front-loaded, and the permission caveat is placed in the second sentence. Every phrase earns its place.

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 zero parameters, an output schema, and annotations, the description covers enough to call the tool at a basic level. However, it leaves out practical guidance about how the check/poll behavior works in detail, what the output represents, and most importantly how this tool relates to notify_check. This is an adequate but not rich description.

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 zero parameters and the schema description coverage is 100%, so there is nothing for the description to add about parameter meaning. The description appropriately focuses on behavior rather than inventing parameter details.

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 states a specific action ('Send a harmless server-side notification check and poll it back') tied to the tool's name and title, so the core purpose is clear. However, it does not explicitly differentiate this from the sibling notify_check or notify_user, so it loses a point on sibling distinction.

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 only usage guidance is the permission prerequisite ('Requires the same human-alert permission as notify_user'), which is a constraint, not a selection rule. It does not say when to use this tool instead of notify_check, when not to use it, or what conditions warrant verification.

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