group_details

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states the success case ('Returns a group object') without mentioning error handling (e.g., invalid identifier), authentication requirements, or any side effects. A more complete description would address these gaps.

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 efficiently conveys the core function. It is front-loaded with the action and result. However, it could include more detail without becoming verbose, such as clarifying the schema_file requirement.

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 simple retrieval task, the description is incomplete. It lacks details about the schema_file parameter's necessity, return format (since no output schema), and error conditions. For a tool with a required unconventional parameter like schema_file, additional context is warranted.

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 description coverage is 100%, so the baseline is 3. The description adds no additional meaning beyond the schema: the group_id parameter is described as 'The unique identifier for the group' and the schema_file parameter instructs the user to read a specific schema file. The tool description does not elaborate further on parameter usage or constraints.

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 'Returns a group object if a valid identifier was provided,' which clearly indicates a retrieval operation for a specific group. It distinguishes from sibling tools like create_group, delete_group, or list_all_groups. However, it does not explicitly mention that the identifier is the group_id parameter, which is already defined in the schema.

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 such as list_all_groups or group_service_account. There is no mention of prerequisites, context for use, or exclusionary conditions. The tool's purpose is implied but not explicitly contextualized among its siblings.

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