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

Annotations already declare destructiveHint=true and openWorldHint=true, so the bar is lower, and the description does add real value by disclosing that channel notifications may be dispatched as a side effect. However, it never explains what 'refresh' destroys or mutates, nor whether the notification dispatch is conditional on configuration or alert severity.

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 clause, front-loaded with the action and scoping the side effect with 'may'; nothing is wasted. It is arguably too terse for a destructive, open-world tool, which keeps it short of a 5.

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?

With no parameters and an output schema present, the description does not need to cover return values. But for a tool flagged destructive and open-world, it omits when to run it, what state it alters, and when the channel notifications fire, leaving meaningful gaps.

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 tool takes zero parameters and schema coverage is 100%, so there is nothing for the description to clarify. Baseline 4 applies for a parameterless tool.

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 verb and resource ('Refresh alerts') plus a side-effect clause, so the general intent is inferable, but 'refresh' is ambiguous — it does not say whether it re-scans for new alerts, recomputes existing ones, or both. It also does not distinguish itself from close siblings like notifications_list, notifications_ack, or notifications_resolve.

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 call this versus notifications_list, notifications_summary, notifications_ack, or notifications_resolve. The agent is left to infer timing and prerequisites entirely.

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