get_lists

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It names the resource ('lists/segments from RogerRoger') but doesn't state pagination limits (max 30 items per page), what happens if no lists exist, or whether this is a read-only operation (though 'Retrieve' implies read-only). The alternative term 'segments' adds useful context about what these objects represent.

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, efficient sentence with zero wasted words. It's front-loaded with the action verb and resource. Could arguably be slightly more informative without violating conciseness, but the current form is appropriately terse.

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 listing tool with pagination, key information is missing: there's no output schema explaining the response structure, no mention of sorting/ordering, and no note about pagination defaults beyond what the schema provides. The schema documents parameters well, but the description doesn't clarify behavior around the 'lists/segments' naming (are these email marketing lists? CRM segments? The term 'RogerRoger' is unexplained).

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 the schema already documents both parameters (page and itemsPerPage) with defaults and max values. The description adds no additional parameter meaning beyond what the schema provides, but given the high coverage, the baseline of 3 is appropriate.

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 states it retrieves all lists/segments from the system, using a specific verb + resource. It's distinct from sibling tools (get_list for single, create_list/update_list for mutations), though it doesn't explicitly differentiate from get_list in the description itself.

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. It doesn't mention pagination behavior in prose, alternative filtering approaches, or when one might prefer another tool. 'All lists/segments' implies full retrieval, but there's no explicit context about trade-offs vs get_list.

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