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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Copy') but doesn't clarify if this is a read-only operation, what permissions are required, whether it overwrites existing sheets, or how errors are handled. This leaves significant gaps in understanding the tool's behavior beyond the basic action.

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, clear sentence with no wasted words. It's front-loaded with the core action and resource, making it easy to grasp quickly. Every part of the sentence contributes directly to understanding the tool's 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 has an output schema (which reduces the need to describe return values) but no annotations and 0% schema coverage, the description is incomplete. It covers the basic action but lacks details on permissions, error handling, or parameter usage. For a mutation tool with three parameters, this leaves too much unspecified for reliable agent use.

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 schema provides no parameter details. The description mentions 'a sheet from one spreadsheet to another', which implies parameters for source, sheet, and destination, but doesn't explain what these parameters represent (e.g., IDs, names, URLs) or their formats. This adds minimal semantic value beyond what can be inferred from the tool name.

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 ('Copy') and the resource ('a sheet from one spreadsheet to another'), making the tool's purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'drive_copy' or 'sheets_read', which would require more specific context about what makes this tool unique.

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 no guidance on when to use this tool versus alternatives like 'drive_copy' or 'sheets_read'. It lacks context about prerequisites, such as whether both spreadsheets must exist or have proper permissions, and doesn't mention any exclusions or specific scenarios where this tool is appropriate.

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