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

With no annotations, the description carries full burden for behavioral disclosure. It lists actions but doesn't explain that 'details' and 'default_content' require template_id, whether results are paginated, or any other behavioral traits. The description adds little beyond the schema's parameter docs.

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 concise and front-loaded, naming the resource and then the actions in a clear list. It wastes no words, though the parenthetical for 'default_content' is slightly redundant with the action name. Still, it's efficient and scannable.

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?

The tool has 4 parameters and 3 distinct actions, but the description doesn't specify which parameters are required for each action (e.g., template_id is needed for details/default_content), what the return shape looks like, or how count/offset apply across actions. Given no output schema and no annotations, this is a significant completeness gap.

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 baseline is 3. The description adds semantic grouping by associating each action with its output, but it does not add new parameter-level details beyond what schema already provides. It earns the baseline, not more.

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 resource (email templates) and enumerates three distinct actions (list, details, default_content), which distinguishes it from sibling tools focused on other Mailchimp resources. However, it lacks a strong action verb like 'retrieve' or 'manage', so it's slightly less direct than ideal.

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 explains what actions are available but gives no guidance on when to use this tool versus alternatives (e.g., mailchimp_campaigns or mailchimp_landing_pages). It does not mention prerequisites or typical use cases, leaving the agent to infer usage from the sibling names alone.

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