signupgenius_list_created_expired

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

The description adds useful behavioral disclosure beyond the readOnlyHint annotation by stating that v3 returns active and expired records together, and that client-side filtering on enddate is necessary. This is valuable because it warns the agent that the tool does not actually return only expired signups despite the name.

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?

The description is a single concise sentence that is front-loaded with the alias relationship and then explains the v3 behavior and filtering requirement. Every phrase carries meaningful information, with no wasted words.

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?

Although there are no parameters and a readOnly annotation, the description is incomplete because it never explicitly states what the tool returns. It relies on the agent already knowing what signupgenius_list_created_active does, and there is no output schema to fall back on. The agent is left without a clear understanding of the list structure or return behavior.

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 input schema has zero parameters, so per the rubric the baseline is 4. The description does not need to add parameter details because there are none to explain.

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 does not clearly state what the tool does. It calls it an 'alias of signupgenius_list_created_active', which is ambiguous and does not differentiate it from other siblings. The name implies it lists expired created signups, but the description says v3 returns active + expired together, making the purpose confusing rather than specific.

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 guidance on when to use this tool versus alternatives such as signupgenius_list_created_active or signupgenius_list_created_all. The only operational note is 'Filter on enddate client-side', which is a filtering instruction rather than a usage guideline.

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