Get an endpoint group

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds the required permission scope (view_endpoints), which is genuinely useful behavioral context, but says nothing about error behavior for missing IDs or what the response contains.

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?

Three short sentences, front-loaded with the action, so an agent can parse the intent immediately. The first two sentences restate the same fact ('Get an endpoint group' / 'Gets a specific endpoint group by its ID'), which is minor redundancy rather than bloat.

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?

With rich annotations, an output schema and full schema description coverage, the description is sufficient to call the tool correctly. However, it leaves the agent without guidance on how org_id interacts with group_id or when a get versus list call is appropriate, which is a noticeable gap for a lookup tool in a large sibling set.

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 all four parameters are documented in the schema itself, and the description's 'by its ID' merely echoes group_id. Nothing is added about org_id scoping, the meaning of verbose, or response_format selection beyond what the schema states.

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?

States a specific verb and resource (get an endpoint group) and clarifies that it fetches a single group by ID, which distinguishes it from the list-style siblings such as action1_list_endpoint_groups. It never names a sibling explicitly, so differentiation is only implicit.

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 offers no when-to-use guidance: nothing tells the agent to prefer this over action1_list_endpoint_groups or action1_list_group_contents, or what to do if the ID is unknown. The only contextual hint is the permission requirement 'Perm: view_endpoints'.

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