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

Annotations only declare readOnlyHint=true; the description adds genuinely new behavioral context by scoping results to 'current employees' (implying inactive/terminated records are excluded) and revealing that hierarchy is returned as a flat list with a reports_to_employee_id rather than a nested tree. It omits size/pagination limits, which matters for a whole-org dump.

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 sentence that front-loads the operation, then the returned fields, then the question it answers. No filler.

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 no input parameters and no output schema, the description must carry the return-shape burden, and it does name the key fields and the manager-id linkage. It stops short of describing ordering, pagination, or volume, which is a modest gap for an org-wide listing.

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 tool takes zero parameters, so the baseline is 4; there is nothing for the description to disambiguate with the schema coverage at 100%.

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 concrete verb and resource ('List all current employees') plus the exact fields returned (manager's reports_to_employee_id, job title, role) and the question it answers. An agent can tell this produces a reporting hierarchy rather than a plain roster, though it never names talenthr_list_employees as the distinction.

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 phrase 'to answer who reports to whom' implies the use case, but there is no explicit when-to-use versus talenthr_list_employees or talenthr_get_employee, and no stated exclusions. The agent must infer routing from the sibling names alone.

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