copy_range

Destructive

Copy a range of cells to another location within a worksheet. Specify source and target ranges to duplicate data without altering the original.

Instructions

Copy a range of cells to another location.

TDQS

C2.6/5.0
Behavior2/5

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

The annotations declare destructiveHint=true, so the agent knows this is a mutation, but the description does not disclose what gets destroyed or overwritten. It does not explain that copying to an occupied target may replace existing cell contents, which is critical behavioral context for a destructive operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is front-loaded and free of filler, but it is under-specified for a seven-parameter destructive mutation. Conciseness is not the issue; the description is too thin for the tool's complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, sparse annotations, and very low schema description coverage, the description should carry more weight. It omits overwrite behavior, range format expectations, dry_run semantics, and target sheet defaults, leaving significant gaps for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 14% across seven parameters, so the description must compensate—but it provides no detail on parameter meaning. It does not specify the expected range notation for source_start, source_end, or target_start, whether target_start is a top-left anchor, or what dry_run does.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ("Copy a range of cells") and a destination ("to another location"), which is clear enough to understand the operation. It does not differentiate from sibling tools like copy_worksheet or delete_range, leaving the agent to infer the distinction from names alone.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives, no prerequisites (e.g., target sheet must exist), and no exclusions. The agent is told what it does but not when to choose it over sibling operations.

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