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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is fully covered. The description adds only the 1-14 day window (which the schema also states) and the fact that top replies are included; it says nothing about result volume, per-reply grouping, or whether the window is calendar or rolling days.

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 sentences, no filler, with the return content front-loaded and the routing condition second. Every clause carries information an agent needs.

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 only two parameters, no output schema, and rich annotations, the description is nearly sufficient: it says what comes back (views, likes, top replies) and when to call it. The remaining gap is the shape of the output, e.g. how many top replies are returned and whether totals are aggregated — modest for a read-only stats tool.

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 100%, so the schema already documents both parameters. The description's "1 to 14 days" and "for an account" merely echo the schema's bounds rather than adding format, default, or semantic detail.

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 specific verb and resource: views and likes earned by cloud patrol replies, plus scope (1-14 days, top replies). It is clearly an analytics read rather than a configuration or log operation, but it never names the nearby cloud_patrol_log / get_cloud_patrol siblings to sharpen the 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?

"Applies when the user asks whether patrol is working or which keywords perform" gives a concrete trigger condition tied to user intent. There is no statement of when not to use it and no named alternative for the log-vs-stats choice, so it stops short of a 5.

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