get_permission_group

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

No annotations are provided, so the description carries the behavioral disclosure burden. It transparently indicates a read operation by saying 'Get details,' but it does not disclose access requirements, error behavior, or what 'details' encompasses, which would add useful context for an agent.

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 one short, front-loaded sentence with no filler. Every word adds meaning, and the core action and resource are immediately visible.

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, the description is minimally adequate, but with no output schema or annotations it does not specify the returned shape, permission requirements, or relationship to list_permission_groups. The agent can invoke it correctly from the schema, but richer context would improve selection confidence.

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 schema already documents account_id and group_id. The description does not add further parameter-level detail beyond naming the resource type, which meets only the baseline expected from the schema.

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 action (get details) and a specific resource (IAM permission group), making the tool's purpose clear. It differentiates reasonably from sibling list tools like list_permission_groups by implying a single-group lookup, and from get_resource_group by naming IAM permission group specifically.

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 gives no explicit guidance on when to choose this tool over alternatives such as list_permission_groups or get_resource_group. Usage context is only weakly implied by the word 'get' and the singular 'a permission group'.

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