calendar_task_lists

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

No annotations are provided, so the description carries the full burden. It does not state that this is a read-only operation, whether it requires auth, whether pagination applies, or what the response shape is beyond 'names'. The one genuinely useful disclosure — that the values feed the `list` argument elsewhere — is the only behavioral detail 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 text is short but ends in a dangling 'Args:' fragment, which is noise from an incomplete template and misleads the agent into looking for arguments that do not exist. The remaining sentence is not front-loaded as a verb+object action statement.

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?

There is no output schema, so the description is responsible for conveying return values; it only hints that names are returned. For a tool whose whole purpose is producing identifiers for other calls, the agent is left unsure whether it gets a list of strings, objects with ids, or counts.

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 tool takes zero parameters, so per the baseline this scores 4. However the trailing dangling 'Args:' indicates a truncated or omitted documentation block, which is a defect even though there are no parameters to document.

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 fragment 'The Google Tasks lists' identifies the resource and implies a read of task lists, and the parenthetical tells the agent the returned names can be used as `list` elsewhere. But it is a noun phrase with no verb, no statement of what is returned (names only? ids? ordering?), and it does not distinguish itself from calendar_tasks or calendar_task_list_create/delete.

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?

There is no explicit when-to-use or when-not-to-use guidance. The nested hint that names are usable as `list` in other task ops weakly implies 'call this before task ops', but the agent must infer that; nearby siblings like calendar_task_list_create and calendar_task_list_delete are not mentioned.

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