get_ad_user_or_group

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

No annotations are provided, so the description must carry the full behavioral disclosure burden. It only says 'Get detailed information' and does not mention lookup behavior, authentication needs, error conditions, or what happens when the AD user or group is not found.

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 sentence with no filler. The action and target are front-loaded, making it easy to scan and understand immediately.

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 one-parameter tool with an output schema, so the basics are covered. However, the description lacks when-to-use guidance and behavioral context, leaving the agent with only the minimal information needed to invoke it.

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 schema already provides 100% coverage by describing ad_id as 'AD user or group ID.' The description adds no additional parameter semantics beyond echoing the resource type, so it meets the baseline without adding value.

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?

Description uses the verb 'Get' with a specific resource, 'a specific AD user or group,' making the operation clear. It doesn't explicitly differentiate from the sibling search_ad_users_or_groups, so it misses the chance to distinguish itself by contrast.

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 given on when to use this tool versus alternatives. The obvious sibling, search_ad_users_or_groups, is never mentioned, leaving the agent to infer the distinction between 'get specific' and 'search' without support.

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