beta_groups__list

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is clear. The description does not contradict these and adds the HTTP method context. No additional behavioral nuance (e.g., pagination defaults, rate limits) is provided, but with the annotations covering the critical safety aspects, the description is adequate.

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 extremely concise at two sentences with no wasted words. It front-loads the core purpose and includes the HTTP endpoint for technical context. One could argue the endpoint is redundant with the tool's behavior, but it's not harmful.

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?

Given the tool has 13 parameters, no output schema, and is a simple list operation with rich annotations, the description is minimally adequate. It doesn't explain return value format or pagination behavior (e.g., how limit and next_url interact), but the schema covers parameters well. For a read-only list tool, this is acceptable but not exemplary.

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 100% description coverage, so the schema already documents all 13 parameters thoroughly. The description adds no new semantic meaning beyond what the schema provides (e.g., it doesn't clarify edge cases or usage patterns for parameters like filter_app or filter_builds). Baseline of 3 is appropriate.

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 clearly states 'List beta groups' which is a specific verb+resource combination. It distinguishes itself from sibling tools like beta_groups__create, beta_groups__get, beta_groups__delete, and beta_groups__update. The HTTP method hint reinforces the read-only nature.

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 a minimal usage hint via the HTTP endpoint, but it does not explicitly state when to use this over other list tools (e.g., apps__beta_groups__list) or provide when-not-to-use guidance. No alternative tools are named.

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