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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and closed-world scope, so the safety profile is fully covered by structured data. The description adds value by concretely naming the metrics returned (month vs. last, all-time, supporter count, pending count), but says nothing about freshness, caching, or data staleness.

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 that leads with the resource ('headline numbers from the creator dashboard') and then lists the four metric groups. No filler, though the colon-and-list construction is slightly dense.

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 an output schema present, the description is not obligated to explain return structure, and it correctly focuses on what the summary contains at a high level. The only gap is the absence of any scoping note (whose dashboard) or distinction from get_analytics.

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 4 baseline applies. No parameter information is missing or 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?

The description states a specific resource (creator dashboard summary) and enumerates exactly what the returned numbers are: month-over-month revenue, all-time total, supporter count, pending approvals. It is clear what the tool does, but it does not differentiate itself from siblings like get_analytics or get_wrapped, which could also plausibly return dashboard-style figures.

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: describing headline figures for a dashboard suggests 'use this for a quick overview', but the description never says when to prefer this over get_analytics or get_wrapped, nor states any prerequisites (e.g. that it returns only the authenticated creator's own data). No explicit when/when-not guidance is given.

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