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 mentions the actions but doesn't clarify critical aspects like permissions required (e.g., edit access to the spreadsheet), whether deletions are permanent, how duplicates are named by default, or error handling. For a mutation tool with multiple actions, this is a significant gap in transparency.

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, efficient sentence that front-loads the core functionality (rename, delete, duplicate) and specifies the resource (sheet tab within a spreadsheet). There is no wasted verbiage, and every word earns its place in conveying 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's complexity (6 parameters, mutation actions) and the presence of an output schema (which handles return values), the description is minimally adequate but incomplete. It lacks usage guidelines, behavioral details, and parameter context, though the output schema reduces the need to explain returns. For a mutation tool with no annotations, it should do more to guide safe 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?

The description implies parameters like 'action' and 'new_name' but doesn't add meaningful semantics beyond what the schema provides. With 67% schema description coverage (4 of 6 parameters have descriptions), the baseline is 3. The description doesn't compensate for the uncovered parameters (user_google_email, spreadsheet_id) or provide additional context like format examples.

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 specific actions (rename, delete, duplicate) and the resource (sheet tab within a spreadsheet) in a concise verb+resource format. It effectively distinguishes this tool from siblings like 'delete_doc_tab' or 'update_doc_tab' by specifying it's for spreadsheet sheets, not document tabs.

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 prerequisites (e.g., authentication needs), exclusions (e.g., when not to delete a tab), or related tools (e.g., 'list_sheet_tables' for identifying tabs). This leaves the agent with no context for tool selection.

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