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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered; the description adds only the GET endpoint and filter dimensions. It says nothing about pagination behavior, result size or ordering that would help an agent drive repeated calls.

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?

Three short clauses, purpose front-loaded, nothing padded. The telegraphic fragments are efficient though slightly clipped; no information is wasted.

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?

A simple four-parameter list tool with full schema docs and read-only annotations needs little more; the endpoint and filter list round it out. Only the absence of any pagination or result-shape hint keeps it below a 5, given there is no output schema.

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 each parameter is self-documenting, so the baseline of 3 applies. The description repeats that name and identifier act as filters but adds no matching semantics (partial vs exact, case sensitivity) beyond what the schema states.

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?

Names the concrete resource and disambiguates the term by glossing business units as 'departments, teams', then states the filterable fields and underlying endpoint. It is clear what the tool returns a list of, though it never distinguishes itself from the closely-named sibling intellihr_list_business_entities.

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 statement of when to reach for this tool versus alternatives such as intellihr_list_business_entities, and no prerequisite or scoping context beyond the filter fields. A caller has to infer the appropriate use from the name alone.

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