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

With no annotations provided, the description carries full burden for behavioral disclosure. While it states this is a creation operation (implying mutation), it doesn't address critical aspects like required permissions, whether the operation is idempotent, error conditions, or rate limits. The description adds minimal behavioral context 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 well-structured with clear sections (purpose, Args, Returns) and uses minimal sentences. Each section earns its place by providing necessary information without redundancy. The only minor improvement would be integrating the purpose statement more seamlessly with the parameter explanations.

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 moderate complexity (creation operation with 3 parameters), no annotations, and an output schema that only specifies return type (not content), the description is adequate but incomplete. It covers the basic operation and parameters but lacks behavioral context, error handling, and detailed output information that would be helpful for an agent.

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?

With 0% schema description coverage, the description provides essential semantic context for all three parameters through the Args section, explaining what each parameter represents. This significantly compensates for the lack of schema descriptions, though it doesn't provide format details (e.g., email validation, ID patterns) or constraints beyond basic requirements.

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 tool's purpose with a specific verb ('Creates') and resource ('new sheet within an existing spreadsheet'), making it immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'create_spreadsheet' (which creates entire spreadsheets rather than sheets within them), though the distinction is implied by the description's wording.

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., needing an existing spreadsheet), compare it to similar tools like 'create_spreadsheet', or specify scenarios where this operation is appropriate versus other sheet-related tools in the sibling list.

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