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

Annotations already declare openWorldHint=true and destructiveHint=true, so the agent knows this reaches outside the system and can destroy state. The description contributes the useful detail that notifications may be pushed to configured channels, but it never says what actually gets destroyed or consumed (e.g., whether alerts are marked read or cleared), which is the key gap given destructiveHint.

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 short clauses with the action front-loaded and the side effect second; nothing is padded. It is arguably too terse for the risk profile, but that is a completeness issue rather than verbosity.

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?

An output schema and annotations cover return shape and safety, so the description need not explain those. What remains unexplained is material: what "refresh" does to existing alert state (destructiveHint=true), and when "may notify" fires — none of which the structured fields answer.

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, so there is nothing for the description to disambiguate; the baseline applies. No parameter claim in the description is misleading.

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?

"Refresh alerts" names a resource and an action, but "refresh" is ambiguous in this namespace — it could mean re-fetch, re-evaluate, or re-emit alerts. It does not distinguish itself from notifications_list, notifications_summary, notifications_ack, or notifications_resolve, so an agent cannot tell from the description which of the five to reach for.

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 statement of when to use this versus notifications_list (read them) or notifications_ack/notifications_resolve (act on them). The "may notify configured channels" clause hints at a side effect but gives no conditions or prerequisites for calling it.

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