merit_list_departments

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

There are no annotations, so the description carries the behavioral burden. It discloses that the call takes no filters and identifies the endpoint, which implies a read-only listing operation. However, it does not mention permissions, response shape, pagination, or any rate-limit expectations. For a simple list tool this is adequate but not rich.

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 a single compact sentence that front-loads the action and resource, then adds the endpoint and the key behavioral constraint. Every word earns its place with no redundancy.

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 zero-parameter list tool with no output schema, the description covers the essential facts: what it returns conceptually, the endpoint, and the absence of filtering. It could additionally describe the response structure or pagination, but such omissions are minor given the tool's simplicity.

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 has zero parameters and the schema is empty, so parameter documentation is inherently unnecessary. The description reinforces this with 'No filters,' making it clear that no input is required. This matches the baseline for zero-parameter tools.

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 states the exact action ('List'), the resource ('departments'), and the product context ('Merit Aktiva'), and even includes the endpoint. This clearly distinguishes it from the many sibling list tools that target different resources like locations, banks, projects, and customers.

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 makes the usage context clear: call this when you need the full list of Merit Aktiva departments, with no filters. It does not explicitly name alternatives, but the resource name is unique among siblings and there is no competing department-list variant, so the intended use is unambiguous.

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