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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'List' weakly implies a read-only operation, but the description never states that, nor does it describe scope (all sheets? within a file?), pagination, or return shape.

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?

A single short sentence with no redundancy, so it is not verbose, but the brevity comes at the cost of under-specification rather than economy of expression.

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?

With no output schema and no annotations, the description must explain what a caller gets back; it says nothing about the return payload or how results are scoped. For a list tool in a family of similar sheet operations, this is an incomplete definition.

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?

There is a single optional parameter 'detail', fully described in the schema as 'Task-specific details from the objective.' Schema coverage is 100%, so the baseline of 3 applies; the description adds no additional meaning about how detail influences the listing.

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 names a verb ('list') and resource ('sheets'), so the intent is inferable, but it is wrapped in a generic 'Run Google sheets action:' template that adds nothing. It does not distinguish this from the sibling get_sheet, which an agent could easily confuse for the same read operation.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as get_sheet or generate_sheet. The agent is left to guess whether 'list' means enumerate sheet names, enumerate tabs within a spreadsheet, or something else.

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