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 ('Reply to') which implies a write operation, but doesn't mention permissions required, whether replies are editable/deletable, rate limits, or what the output contains. This leaves significant gaps for a mutation tool.

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 that gets straight to the point with no wasted words. It's appropriately sized for a straightforward tool and is front-loaded with the essential information.

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?

While an output schema exists (which helps), the description is inadequate for a 4-parameter mutation tool with no annotations. It doesn't explain parameter meanings, usage context, or behavioral aspects like authentication needs or side effects. The existence of an output schema prevents a lower score, but significant gaps remain.

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 all 4 parameters are undocumented in the schema. The description doesn't explain what 'comment_id', 'reply_content', 'spreadsheet_id', or 'user_google_email' represent or how to obtain them. It fails to compensate for the complete lack of schema documentation.

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 ('Reply to') and target resource ('a specific comment in a Google Spreadsheet'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'reply_to_document_comment' or 'reply_to_presentation_comment' beyond specifying 'Google Spreadsheet' as the context.

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 like 'resolve_spreadsheet_comment' or 'create_spreadsheet_comment'. The description lacks any context about prerequisites, such as needing an existing comment to reply to, or when this operation is appropriate.

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