beta_testers__beta_groups__list

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read-only operation. The description adds the specific relationship and GET endpoint but does not disclose pagination behavior, return format, or permission requirements, providing only modest additional context.

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 compact sentence with the endpoint reference, containing no redundant or filler information. It is front-loaded and immediately communicates the core purpose.

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 straightforward read-only list operation, the description, annotations, and schema are largely sufficient. Pagination and field selection are covered by the schema parameters, and the 'List' semantics imply a collection response, though the absence of an output schema means the response shape is not explicitly disclosed.

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 provides clear descriptions for all four parameters (id, limit, next_url, fields_betaGroups) with 100% coverage, so the description does not need to compensate. The description itself adds no parameter-specific detail, so the baseline score of 3 applies.

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' with the resource 'beta groups' and clearly scopes them to 'belonging to a beta tester', which distinguishes it from the inverse sibling tool beta_groups__beta_testers__list. The endpoint URL further reinforces the exact operation.

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 does not explicitly state when to use this tool versus alternatives such as beta_groups__beta_testers__list, nor does it mention any exclusions or prerequisites. The intended context is only implied by the tool name and the phrase 'belonging to a beta tester', which is not sufficient guidance.

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