copy_range

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

Although the annotation destructiveHint=true exists, the description does not disclose what destructive behavior occurs (e.g., overwriting target cells). It adds no behavioral context beyond the annotation, leaving key safety implications unexplained.

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 a single concise sentence with no fluff, but it is under-specified for a tool with 7 parameters. Conciseness is good, but it sacrifices necessary detail, making it minimally adequate.

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 (7 parameters, destructive annotation, no output schema), the description is incomplete. It does not clarify what happens on execution (e.g., return value or confirmation) or explain dry_run, overwriting behavior, or cross-sheet copying via target_sheet.

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 description coverage is 0%, so the description must compensate, but it does not explain parameter meanings, formats, or relationships. Names like source_start and target_start are self-explanatory at a high level, but critical details such as cell reference format or the role of target_sheet are omitted.

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 a specific verb (copy) and resource (range of cells) with a destination (another location). It distinguishes from sibling tools like copy_worksheet by specifying 'range' rather than whole worksheet.

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. It does not mention prerequisites, edge cases, or why to choose copy_range over similar tools like copy_worksheet.

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