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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains each action's purpose, including the 'ping' health-check behavior and the required IDs for sub-resource actions. It stops short of discussing rate limits or read-only guarantees, but the action-by-action breakdown is substantial.

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 well-structured: a brief overview sentence followed by a scannable, enumerated list of actions. Each action's explanation is concise and information-dense, with no redundant phrasing.

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?

Given the tool's complexity (7 parameters, 11 distinct actions), the description is thorough, covering every action and its required parameters. It also describes return content for key actions. Pagination behavior is absent, but the schema covers the count/offset parameters, so the description is complete enough.

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 each parameter with 100% coverage, so the baseline is 3. The description adds further meaning by linking each ID parameter to its specific action and summarizing the expected output (e.g., 'plan, contact, total subscribers, industry benchmarks' for overview). This adds real interpretive value beyond the schema.

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 tool as handling account-level administration, listing the specific resources it covers (plan, API health, domains, etc.). This distinguishes it from sibling tools like mailchimp_audiences or mailchimp_campaigns, which address different domains.

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 opening sentence establishes a clear context for when to use this tool (any account-level administrative task). It does not explicitly name alternatives or exclusion criteria, but the resource scope is unambiguous and the action enumeration provides concrete deployment guidance.

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