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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action ('Append rows') but lacks details on permissions required, rate limits, error handling, or what the output might contain. This is inadequate for a mutation tool with zero annotation coverage.

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 extremely concise—a single sentence with no wasted words. It's front-loaded with the core action, making it easy to parse quickly, which is ideal for brevity.

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 (a mutation tool with 3 parameters, 0% schema coverage, no annotations), the description is insufficient. It doesn't explain parameter semantics, behavioral traits, or usage context. While an output schema exists, the description doesn't provide enough guidance for effective tool selection and invocation.

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 by explaining parameters. It mentions 'rows' and 'sheet' but doesn't clarify the meaning of 'spreadsheet', 'range', or 'values' parameters beyond what's implied. This adds minimal value over the bare schema, failing to address the coverage gap.

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 verb ('Append') and resource ('rows to the end of a sheet'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'sheets_write' or 'sheets_add_table', which might also modify sheet content, so it doesn't reach the highest score.

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. It doesn't mention sibling tools like 'sheets_write' (which might overwrite vs. append) or 'sheets_add_table', nor does it specify prerequisites or contexts for usage, leaving the agent without direction.

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