ise_ers_get_identitygroup

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

No annotations are provided, so the description carries the full burden. 'Get' implies a read operation, which is reasonable. However, it doesn't disclose whether authentication/credentials are required, what happens if the ID doesn't exist (error vs null), or any pagination/result shape for a GET that returns a single object. It's a minimal but not misleading behavioral disclosure.

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 short sentence. It's efficient and front-loads the key action. However, it could have used a bit more space to explain the id parameter format, but as-is it is concise with no wasted words.

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?

This is a simple single-object getter with 2 params and no output schema. The description conveys the core purpose adequately. Missing context: no information about how to obtain the ID (from list/search), and no mention of the returned object format. However, for a straightforward getter tool, the description is near-minimum-viable but could be more helpful.

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 50%. The deployment parameter is well-documented in the schema with valid formats and a reference to ise_list_deployments. However, the 'id' parameter has no description in the schema, and the tool description doesn't explain what format the ID takes or how to obtain it (e.g., from a list/search call). Given partial coverage, the description adds nothing beyond naming the param in purpose.

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 'Get a single Identity Groups object by ID' uses a specific verb (Get) plus a specific resource (Identity Groups object) scoped by ID. It clearly distinguishes from the list_identitygroup and search_identitygroup siblings, though it doesn't explicitly compare to them.

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 guidance on when to use this tool vs alternatives like ise_ers_search_identitygroup or ise_ers_get_by_name. It doesn't state when you'd have an ID vs name to look up, or mention prerequisites. The schema's deployment param references ise_list_deployments, but the description itself offers no usage context.

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