sheets_update_borders

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

The annotations provide idempotentHint=true and destructiveHint=false, but the description adds no behavioral context beyond that. It fails to clarify whether unspecified border sides are preserved or cleared, or how to remove borders, which are important operational details for this 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, front-loaded sentence with no filler, efficiently conveying the core purpose. While concise, it is slightly thin for the tool's complexity, so it does not reach a perfect score.

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 complex nested borders schema, no output schema, and many related siblings, the description is too sparse. It omits key details about partial border updates, clearing borders, and how this tool relates to formatting or border-reading tools, making it incomplete for reliable 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?

With schema description coverage at 0%, the description bears full responsibility for parameter semantics but provides none. It does not explain the A1 range notation or the structure/meaning of the borders object, leaving the rich nested schema to stand alone without guidance.

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 states a clear verb ('Update') and resource ('borders of cells in a Google Sheet'), making the tool's function immediately understandable. However, it does not distinguish this tool from siblings like sheets_format_cells or sheets_get_border_map, so it earns a 4 rather than a 5.

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?

There is no guidance on when to use this tool versus alternatives. The description does not mention exclusions, prerequisites, or related tools, leaving the agent without direction on tool selection beyond the tool's name.

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