get_user_details

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only signals a read operation through the word 'Get' but does not mention return behavior, authentication requirements, scoping, or any other operational traits. This is minimal but not actively misleading.

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 concise and front-loaded with no filler words, which is positive. However, it is under-specified to the point of being a near-tautology of the tool name, and it lacks the structural detail needed to make the short text useful.

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 tool with three parameters, no annotation coverage, and no schema descriptions, this description is incomplete. The output schema may explain return values, but the input semantics and selection context are left entirely unspecified, so an agent cannot confidently invoke the tool.

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 0%, and the description adds nothing about the parameters zoid, zuid, or email_address. An agent cannot determine which identifier is authoritative, how the optional email_address affects the lookup, or what the required parameters represent.

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 verb and resource ('Get specific user details'), so it is not missing entirely, but it is essentially a restatement of the tool name and leaves 'details' undefined. It does not distinguish this tool from sibling tools like get_user_storage_details or get_account_details, making the purpose vague for an agent.

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?

There is no guidance about when to use this tool versus alternatives such as get_all_users, get_user_storage_details, or get_account_details. The phrase 'specific user' weakly implies a single-user lookup, but no context, prerequisites, or exclusions are provided.

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