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

No annotations are provided, so the description carries the full burden, and it discloses nothing: not whether a sheet is created, overwritten, or derived; not auth requirements; not the effect on an existing spreadsheet. It is effectively opaque beyond the name.

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?

One short sentence, but its brevity comes from under-specification rather than efficiency. "Run Google sheets action:" is filler that consumes the whole description without conveying information.

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 mutation-style generate action with no annotations, no output schema, and no explanation of what "generate" produces, the description is far too thin. An agent cannot confidently call it or predict the result.

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?

Single parameter with 100% schema description coverage, so the schema already documents "detail" as task-specific objective details. Per the baseline for high coverage, a 3 is appropriate; the description adds no meaning beyond it.

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?

"Run Google sheets action: generate sheet" restates the tool name in wrapper phrasing without adding specificity. It does not distinguish generate_sheet from sibling create_sheet, converse, or update_sheet, all of which operate on the same resource.

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 guidance on when to use this tool versus create_sheet or the other sheets siblings. The agent is left to infer that "generate" differs from "create" purely from the name, which is not explained.

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