Get department

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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about read-only semantics, permission requirements, or what happens when the accountId has no department. Only the bare 'by accountId' lookup hint is offered.

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?

It is short and front-loaded, but the brevity comes from under-specification rather than efficiency: nearly every sentence slot that could carry useful information is empty.

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 one-parameter lookup the bar is low, but with no annotations, no output schema, and no mention of not-found behavior or the relationship to 'get_departments', the definition leaves gaps an agent would hit immediately.

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% and the single parameter (accountId) is documented in-schema as the ALSO Cloud Account ID. The description repeats the parameter name but adds no format or sourcing guidance beyond the schema, so the baseline of 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 'GetDepartment — department by accountId' essentially restates the tool name and title, adding only the parameter name. It does not say whether this returns a single department object or clarify the scope versus the sibling 'get_departments'.

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 indication of when to use this tool rather than 'get_departments' (list) or 'get_department' vs 'get_company'/'get_reseller' lookups. The singular/plural relationship with its closest sibling is left entirely to inference.

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