create_tasklist

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

No annotations are present, so the description must fully disclose behavior. It notes that emojis render fine, which is a helpful behavioral detail, but fails to mention side effects, permissions, limits, or return value. The word 'Create' implies mutation, but deeper transparency is missing.

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?

Two sentences with no extraneous words. The first sentence states the primary action concisely; the second gives a specific, useful tip. Every sentence earns its place.

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?

Despite being a simple creation tool with one parameter, the description does not explain what a task list is, what the return value is, or how it relates to other tools like 'create_task.' With no output schema, the agent lacks information about the result, making it incomplete for effective planning.

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%, providing a baseline of 3. The description adds value by noting that emojis are supported in titles, which is not evident from the schema's generic 'Title of the new task list' description. This extra nuance helps the agent choose appropriate title values.

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 'Create a new task list,' establishing a specific verb and resource. The sibling tools (list, get, update, delete) imply different actions, so the purpose is distinct. However, it does not explicitly differentiate from 'create_task' or mention that task lists are containers for tasks, which could be improved.

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?

No guidance is provided on when to use this tool versus alternatives like 'create_task' or 'update_tasklist.' The description lacks context on prerequisites, such as whether a user or workspace must be specified, or when creating a new list is appropriate.

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