beta_groups__beta_testers__list

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is clear. The description adds no further behavioral details (e.g., pagination behavior or whether only active testers are returned), but it does not contradict the annotations.

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 sentence with the endpoint token, front-loading the action and object. There is no filler or redundancy.

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?

This is a simple read-only list tool with good annotations and fully described parameters; the description adequately communicates the scope. It lacks explicit return-format or pagination prose, but the schema documents limit/next_url and the endpoint implies a standard list response.

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?

Schema coverage is 100%: id, limit, next_url, and fields_betaTesters are all documented in the input schema. The description adds no additional parameter meaning, but the schema already carries that burden.

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 identifies both the resource ('beta testers') and the scope ('belonging to a beta group'), clearly distinguishing it from broader tools like beta_testers__list. The endpoint pattern reinforces the relationship.

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 implies usage when you need the testers for a specific beta group (requiring the id parameter), but it does not explicitly contrast with sibling tools such as beta_testers__list or builds__individual_testers__list. There is no when-not-to-use guidance.

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