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

Annotations already declare readOnlyHint=true, so the safety profile is covered and the bar is lower. The description adds useful context by naming the fields the call surfaces and the underlying GET endpoint, but says nothing about pagination, result volume, or account scoping that a listing tool typically needs.

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 dense sentence front-loads the purpose and field list, then tacks the API path on the end. Every clause earns its place and there is no filler.

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 output schema and no parameters, the description carries the burden of telling the agent what comes back, and the field enumeration does that reasonably well. It stops short of describing pagination or account scoping, which are the remaining gaps for a list endpoint.

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, which by the rubric sets a baseline of 4 — there is no parameter syntax for the description to clarify or obscure. The enumerations in the description instead describe outputs, not inputs, so nothing further is required here.

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 (List) and resource (membership levels) and even enumerates the salient fields returned — name, fee, renewal period, individual vs bundle, public applicability. It does not distinguish itself from the closest sibling, wildapricot_list_member_groups, leaving an agent to infer the difference between levels and groups.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as wildapricot_list_member_groups. The phrase about public applicability describes a returned field rather than a usage condition, so the agent gets no routing help.

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