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

The annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the parenthetical clarification that business entities are legal employers and notes the underlying GET endpoint, but does not add behavioral details such as pagination behavior or response contents.

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 two short, front-loaded statements with no filler. It gives the resource meaning immediately and appends the endpoint, keeping the definition easy to scan.

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?

This is a simple read-only list tool with two fully documented parameters and annotations that cover its safety profile. The description does not explain return values, but given the low complexity and fully specified input schema, an agent has enough information to invoke it correctly.

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%, so both page and limit are fully documented in the schema. The description adds no parameter-specific meaning beyond what the schema already provides, which is acceptable at the baseline for full schema coverage.

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 clearly identifies the resource as the organisation's business entities and clarifies them as legal employers. It is specific enough to distinguish the resource from generic people or jobs, but it does not explicitly differentiate this tool from nearby siblings such as list_business_units or list_locations.

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 description provides no guidance on when to use this tool, when not to use it, or which sibling list tool to choose instead. The endpoint reference implies a straightforward list operation, but the agent must infer all usage context from the name and schema.

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