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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds nothing beyond that — no mention of default filtering (status defaults to 'open'), pagination behavior, or ordering.

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?

It is extremely short, but that brevity comes from under-specification rather than efficiency — there is no front-loaded detail to speak of, so it fails to be appropriately sized for a five-parameter tool.

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 exists, so return values need not be explained. Still, for a five-parameter tool with zero schema descriptions and several filtering siblings, the definition omits the filtering/pagination context an agent needs to call it correctly.

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 description coverage is 0% across five parameters (limit, cursor, status, severity, connection_context), and the description names none of them. Critical semantics such as the 'open' default for status, the 1-100 limit range, or the opaque cursor format are left entirely undocumented.

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?

States a clear verb (List) and resource (notifications), so an agent knows the general operation. However, it does not distinguish this from close siblings like notifications_scan, notifications_summary, or notifications_ack, nor clarify the scope of what is listed.

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 tool versus notifications_scan, notifications_summary, or the ack/resolve siblings. The agent must infer that this is the plain enumeration entry point purely from the name.

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