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

No annotations are supplied, so the description carries the full burden. The wording implies a read-only aggregate and tells the agent what the numbers represent, but it never states that it is non-mutating, whether it requires an authenticated profile, or how the week window is defined (calendar week vs rolling seven 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?

One short sentence with the primary content first and the secondary breakdown after; nothing is redundant or padded.

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 no output schema, the description does the needed work by sketching the two parts of the response: the sent-vs-goal comparison and the per-status counts. It falls just short by not defining the week boundary or the set of statuses counted.

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 schema to document and the baseline of 4 applies. The description correctly signals that no scoping inputs exist — the week and status grouping are fixed by the 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 names a concrete resource and scope: applications sent this week against the weekly goal, plus per-status counts. That is enough to distinguish it from applications_list, which lists applications rather than aggregating them, though the verb is implied rather than stated.

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 explicit when-to-use guidance and no mention of alternatives. The agent is left to infer that this is the dashboard/summary call and that applications_list should be used for per-record detail.

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