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. The description adds real value by disclosing the scope of returned content (failing monitors, plugin issues, beacon silence, domain/ownership, safe updates, paused alerts, billing), which tells the agent what a call will surface. It omits ordering, freshness, and whether results aggregate across all sites.

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 naming the resource first, followed by the enumeration. The list is long but each item is a distinct notification category, so it earns its space; a slightly tighter grouping (e.g., 'domain/ownership' vs 'billing') would read cleaner.

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 zero-parameter, read-only tool with no output schema, the description carries the return-value burden well by enumerating what notifications exist. It is nearly complete — only the lack of any note on ordering, aggregation scope, or next-step tooling keeps it from a 5.

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?

There are zero parameters, so per the rubric the baseline is 4. The description correctly adds no parameter detail because there is none to add, and the enumerated categories function as implicit scoping information.

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 names the resource (the dashboard's notifications) and enumerates the exact categories returned, so an agent knows precisely what data comes back. It stops short of explicit sibling differentiation — nothing distinguishes it from get_alert_settings or get_activity_log, which surface related dashboard data.

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?

Usage is only implied: with zero parameters and a read-only listing, the agent can infer this is the 'view current notifications' tool. There is no stated when-to-use, no condition selecting it over get_alert_settings or site_overview, and no mention of how its output relates to the fix/recommendation tools in the sibling set.

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