append_rows_to_sheet

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

With no annotations, the description must disclose behavior. It states 'empty rows' but doesn't clarify default values, formatting, or reversibility. For a mutation tool, this is insufficient to understand side effects or requirements.

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 single sentence is concise, but minimalism comes at the cost of omitted details. It is not verbose, but could benefit from additional context without being wasteful.

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 the complexity (three required params, sibling tools like 'append_rows' and 'insert_rows', no output schema), the description is incomplete. It lacks parameter explanations and usage scenarios, making it insufficient for informed selection.

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?

Schema coverage is 0% and the description does not explain parameters. While 'spreadsheet_id' and 'sheet' are somewhat inferable, 'length' could be ambiguous (number of rows? rows vs columns?). No example or clarification is provided.

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 clearly states the action 'append empty rows' and the target 'to the end of a sheet'. It distinguishes from sibling tools like 'append_rows' (which appends data) and 'insert_rows' (which inserts at a position). The verb and resource are specific.

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 is provided on when to use this tool versus alternatives like 'append_rows' or 'insert_rows'. The description offers no context for selection, leaving the agent to infer based solely on the tool name.

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