Create Reminder List

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It only states the action without mentioning side effects, what happens if a list with the same name already exists, permissions required, or the return value. This lack of detail leaves the agent without important behavioral context, though the description is not misleading.

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 front-loads the verb and object. Every word earns its place, and there is no redundancy or filler. It is appropriately sized for the tool's simplicity.

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 only one parameter and no output schema, so the description is mostly adequate. However, it does not address edge cases like duplicate list names, naming constraints, or what happens on success/failure. Given the low complexity, this is a moderate gap, making the description minimally viable but not complete.

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 input schema fully describes the 'name' parameter with a clear description: 'Name of the list to create.' The description's phrase 'with the given name' adds no new meaning beyond what the schema already provides. Since schema coverage is 100%, the baseline is 3, and the description does not elevate it.

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's function: 'Create a new reminder list with the given name.' It uses the specific verb 'create' and names the resource 'reminder list', distinguishing it from siblings like 'rename-list' and 'delete-list'. This is a clear and unambiguous purpose statement.

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 versus alternatives, such as 'list-lists' to check existing lists or 'rename-list' to modify one. There are no prerequisites, exclusions, or context about when creation is appropriate. The agent must infer usage solely from the tool name and description.

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