merit_list_item_groups

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

With no annotations, the description carries the burden. It correctly implies a read-only operation via 'List', but it does not disclose output format, pagination, or any side effects. For a simple zero-parameter list tool, this is adequate but minimal.

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, front-loaded sentence that contains exactly the needed information: what the tool lists, the endpoint, and the key limitation. No wasted words.

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 tool with no parameters, no output schema, and no annotations, the description is nearly complete. It gives the resource, endpoint, and filtering constraint. The only minor omission is explicit mention of return structure or pagination behavior, but these are less critical for such a simple list operation.

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?

There are 0 parameters and the schema is an empty object, so the baseline is 4. The description adds meaningful clarity by explicitly stating 'No filters', which prevents the agent from assuming query parameters are supported.

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 specific verb ('List'), a clear resource ('Merit Aktiva item groups'), and the underlying endpoint. It is easily distinguished from sibling tools like merit_list_customer_groups, merit_list_vendor_groups, and merit_create_item_groups.

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 'No filters' gives a clear constraint: use this tool when you need all item groups without filtering. However, it does not explicitly mention alternatives or provide when-not-to-use guidance, leaving some inference to the agent.

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