get_group_by_id

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

No annotations are present, so the description must carry the behavioral disclosure burden. 'Get' implies a read-only operation, but it does not disclose the return format, error behavior (e.g., not found), or any required permissions. This is a minimal description that only states the basic action.

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 exactly one sentence, front-loaded with the verb and resource, and contains no filler. It is highly efficient and appropriate for the simplicity of the tool.

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 simple get-by-ID tool with one parameter and an output schema, the description is minimally adequate. However, given the large set of siblings and the absence of any usage or behavioral context, it could do more to help the agent select it appropriately. The output schema exists so return values need not be explained, but the lack of guidance on when to use this tool versus search/list alternatives is a gap.

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 one parameter 'group_id' with 0% description coverage. The description's 'by its ID' clarifies that the parameter is the group identifier, adding some meaning. However, it does not specify expected format or constraints, so the description only partially compensates for the lack of schema documentation.

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 the specific verb 'Get' with the resource 'specific group by its ID', clearly distinguishing it from sibling tools like get_all_groups and search_groups_by_name. It fully answers what the tool does in a single, unambiguous phrase.

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 guidance is provided on when to use this tool versus siblings. While the description implies it is for fetching by known ID, there is no explicit mention of alternatives like searching by name or listing all groups, leaving the agent to infer the appropriate context.

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