List SheetRender templates

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

With no annotations, the description carries the full burden; it discloses that the operation is a read ('lists'), is scoped to the user's account, and returns templates together with their ids. It is silent on ordering, result size/pagination, and account/permission requirements, which keeps it short of a 5 for an un-annotated tool.

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?

Effectively front-loaded: the domain context comes first, then the action, then the routing guidance. The closing 'Takes no arguments' is mildly redundant against the empty schema, and the middle sentence is long, but no sentence is wasted.

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?

Given a no-arg, annotation-free, no-output-schema listing tool, the description supplies the essential context: what it returns, why it exists, and when to call it. Some return-value detail (ordering, size limits) is absent, which is the only real gap.

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 the schema baseline is 4; the description reinforces this with 'Takes no arguments.' No additional parameter meaning is needed or missing.

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 states a precise verb+resource ('lists the templates saved in the user's account, with the id each one needs') and separates itself from siblings by noting that create_dataset and list_datasets take a template_id instead. The opening sentence even establishes the SheetRender domain so the agent understands what a template is here.

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?

It gives an explicit trigger condition ('Call it first whenever the user refers to a template by name') plus the concrete alternative behavior it enables: mapping a name to an id that 'every other tool here takes'. This is a clear when-to-use rule with the tool's role in the workflow spelled out.

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