Administrator: Get_administrator_login

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safe-read profile is covered. The description adds nothing beyond that — no note on what fields constitute 'login details', whether sensitive data is masked, or any auth/permission requirement. It essentially restates the read annotation.

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?

A single front-loaded sentence with zero padding. It is appropriately sized, though its brevity comes at the cost of the missing detail noted elsewhere.

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 one required parameter, no output schema, and simple read annotations, the definition is minimally adequate. However, for a tool whose whole value is the shape of the returned 'login details', the absence of any hint about the response content leaves a real gap.

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% — the single administratorId parameter is documented as 'The Brivo administrator id.' The description adds no format, accepted type, or source guidance, so the baseline 3 applies.

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 names a verb and resource ('Retrieve login details for an administrator'), which is better than a tautology, but 'login details' is left undefined — an agent cannot tell whether this returns username, email, last-login timestamp, or credential info, nor how it differs from the sibling Get_administrator.

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 when-to-use guidance and no mention of alternatives, despite three closely related siblings (Get_administrator, Get_current_administrator, List_administrators). The agent is left to guess which of these to call.

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