manage_task_list

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

With no annotations, the description carries the full behavioral burden. It does disclose that delete and clear_completed are destructive and that create/update are mutating, but it omits details about irreversibility, permission requirements, or side effects on child tasks when deleting a list. The Returns line is minimal but present.

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 appropriately sized, front-loads the core purpose, and uses a clear Args/Returns structure. Each sentence adds necessary information, with no filler or redundant prose.

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 multi-action tool with conditional parameter requirements, the description covers all parameters and the return type adequately. It falls short of a 5 only because it does not explain how to obtain a task_list_id, mention auth prerequisites, or clarify what happens to child tasks when a list is deleted.

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 0% description coverage, but the description fully compensates by enumerating valid action values and specifying which parameters are required for each action: task_list_id for update/delete/clear_completed, and title for create/update. This is essential semantic information that the schema alone does not provide.

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, 'Manage task lists,' and immediately enumerates the exact supported actions: create, update, delete, and clear_completed. This sharply distinguishes it from sibling tools like manage_task, which operates on individual tasks within a list.

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 does not provide explicit guidance on when to use this tool versus related siblings such as list_task_lists, get_task_list, list_tasks, or manage_task. The supported actions imply usage, but there is no stated alternative or exclusion condition.

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