insert-excel-range

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

The description aligns with the destructiveHint annotation by mentioning shifting existing content. It adds context about the body format but does not disclose side effects like permanence or formula behavior.

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 description is short but the first line 'Invoke action insert' is somewhat tautological and vague. The tip is useful, but the structure could be more front-loaded with the core purpose.

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 tool's complexity (multiple required parameters, no output schema), the description lacks details on constructing the address, prerequisites (e.g., worksheet existence), error conditions, or return values. It is minimally adequate.

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 86%, so the baseline is 3. The description adds meaning for the body parameter's shift property but does not elaborate on other parameters like driveId or address, which remain as schema-described path parameters.

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 'Insert blank cells at the given range, shifting existing content,' which is a specific verb+resource combination. It effectively distinguishes from sibling tools like clear-excel-range or delete-excel-range.

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?

The description provides a tip on using the body format with shift 'Down' or 'Right' and suggests when to use 'Down' for blank rows. However, it does not explicitly compare to alternatives or state when not to use this tool.

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