create_beta_group

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true; the description's 'MUTATES' mostly restates that. It adds no details about side effects beyond the annotations, such as whether duplicate names are allowed, whether existing groups are affected, or what permissions are required.

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 front-loaded sentence with no filler. It immediately tells the agent the mutation and target, though it is terse.

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 destructive mutation with three required, undocumented parameters and no output schema, the description is too thin. Annotations cover the safety profile, but the agent still lacks parameter guidance and operational 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?

Schema coverage is 0% for three required parameters, so the description should compensate but does not. It only loosely hints at appId and isInternalGroup via 'for an app' and 'internal or external', and says nothing about name.

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 states a specific verb 'create' and resource 'beta group', plus scope 'internal or external' and 'for an app', so the action is clear. It does not explicitly differentiate from siblings such as list_beta_groups or add_tester_to_beta_group, so it stops short of a 5.

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?

No when-to-use guidance, alternatives, or prerequisites are given. The only cue is 'create', which implies usage but does not help an agent choose between this and add_build_to_beta_group or add_tester_to_beta_group.

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