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

No annotations are provided, so the description carries the entire behavioral burden, and it discloses nothing: no read-only vs. mutating status, no auth/permission requirements, no indication of what is returned or how a sheet is identified. The boilerplate phrase 'Run Google sheets action' adds zero behavioral content.

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?

It is very short and front-loaded, but the 'Run Google sheets action:' prefix is pure template padding that earns no place, and the remainder is under-specified rather than concise. There is no useful structure or content to organize.

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 annotations and no output schema, the description must explain operation semantics, but it supplies nothing — not what a 'get sheet' returns, not how the target sheet is determined, not any prerequisite. For even this simple one-parameter read tool, the definition is materially incomplete.

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 parameter ('detail') and schema description coverage is 100%, so the schema already documents it. The description adds no meaning beyond the schema, which is the expected baseline 3 when the schema does the heavy lifting.

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 reads 'Run Google sheets action: get sheet,' which is effectively the tool name restated with template boilerplate around it. It gestures at a verb (get) and resource (sheet) but conveys no scope, return content, or distinction from siblings like sheets__list_sheets or sheets__generate_sheet.

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 is present at all, and no alternative tools are referenced. An agent cannot tell from this text whether it should call get_sheet, list_sheets, or generate_sheet for a given request.

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