signupgenius_list_signedupfor

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

The readOnlyHint annotation already marks the tool as read-only, and the description aligns with that by saying 'List'. The additional phrase 'personally signed up for' adds slight contextual scope but no deeper behavioral traits such as return format, pagination, or authentication requirements. This is consistent with the annotations and adds only marginal value.

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 action. It contains no redundant or filler content, making it appropriately sized for a zero-parameter tool.

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?

For a zero-parameter, read-only listing tool with no output schema, the description is largely complete. It clearly states what the tool returns. However, it does not clarify the difference from the legacy 'get_my_signups' sibling, leaving a small ambiguity in context.

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 is empty, so there are no parameters to describe. The baseline for zero parameters is 4, and the description correctly makes no claim about parameters. No additional semantic information is needed.

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 uses a specific verb ('List') and resource ('sign-ups the user has personally signed up for'), clearly indicating the tool's function. It differentiates from related sibling tools like signupgenius_list_invited and signupgenius_list_created by specifying the user's own sign-ups, but does not explicitly distinguish from the similar signupgenius_legacy_get_my_signups.

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?

The description provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or exclusions. Given the presence of several similar list tools, the lack of usage direction is a notable gap.

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