mailchimp_lists_get

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only says 'Get details' without explaining what details are included, the response format, or any permissions or side effects. This is minimal and leaves significant unknowns for a read operation.

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, concise sentence that directly states the tool's purpose. It is appropriately front-loaded and contains no unnecessary words, earning a perfect score.

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 simple GET with one parameter and no output schema, the description is functional but minimal. It fails to elaborate on what 'details' means, which could be important for an agent deciding whether to use this tool, but the low complexity prevents a lower score.

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 schema already describes list_id as 'List ID' with 100% coverage, and the tool description adds no further meaning. It doesn't explain where to find the list_id or its format, but the schema provides sufficient baseline, so a middle score 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 the tool retrieves details for a specific list/audience, using the verb 'get' and the resource 'list/audience'. This distinguishes it from sibling tools like mailchimp_lists_list (which lists all lists) and other list-specific tools, though 'details' is somewhat vague.

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 explicit guidance on when to use this tool versus alternatives. The phrase 'specific list' implies an ID-based lookup, but it does not mention alternatives like listing all lists or accessing related resources, leaving the usage context ambiguous.

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