tasks_create_tasklist

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the fact that a task list is created, without mentioning side effects, required permissions, idempotency, or what the response looks like. This is extremely minimal and does not disclose any behavioral traits beyond the obvious mutation.

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 sentence and is not verbose, but it is under-specified. It essentially restates the tool name without adding useful detail. While conciseness is good, the description does not earn its place because it adds no information beyond the tool name.

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?

This is a simple one-parameter creation tool, but the description is still insufficient given the absence of annotations and parameter documentation. It does not explain the return value or any behavioral nuances, leaving the agent without enough context to fully understand the tool's operation.

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 has one required parameter 'title' with 0% schema description coverage. The description 'Create a new task list.' does not mention the title parameter at all, nor does it explain its format, constraints, or role. It fails to compensate for the lack of schema documentation.

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 'Create a new task list.' clearly states the action and resource. It is not vague, but it does not explicitly differentiate from sibling tools like tasks_create (which likely creates a task within a list) or tasks_list_tasklists. The purpose is clear, but the differentiation is only implicit via the name.

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. There is no mention of prerequisites, context, or exclusions. For example, it does not say to use this when creating a new list as opposed to adding a task to an existing list.

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