Create a task list

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

The description adds valuable behavioral context beyond the annotations: the created list is returned, the API accepts only a title, the returned id is central to later task operations, and Google caps lists per account with quota failures surfacing as HTTP errors rather than silent failures. No contradiction with annotations.

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?

Every sentence earns its place: return shape, scope of accepted settings, downstream importance of the id, and quota/error behavior. The description is compact, front-loaded, and free of filler.

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 single-parameter creation tool with no output schema, the description is complete: it states what happens, what is returned, how the result is used, and what error behavior to expect. The low complexity means no significant gaps remain.

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 coverage is 100% and the title parameter is already well documented in the input schema. The description adds context by emphasizing that title is the only accepted setting, which reinforces the schema but does not fundamentally enrich the parameter semantics.

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 opens with a specific verb and resource: 'Creates a new task list and returns it.' It also names the returned fields, distinguishing this creation tool from the many sibling get/update/delete/list tools in the same family.

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 context is clear: this is the tool for creating a list, and the description explains that the returned id becomes the tasklist_id required by task tools. It does not explicitly compare itself to alternatives like update_tasklist, but its role is unambiguous from the description and sibling set.

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