batch_update_cells

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

The annotations include destructiveHint=true, but the description only says 'update' without clarifying that overwrites values. It does not disclose behavioral traits like irreversibility, required permissions, or side effects beyond what annotations provide.

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 concise with a one-sentence summary followed by structured Args and Returns sections. Every sentence serves a purpose with no redundancy.

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?

The tool is complex with multiple ranges, but the description lacks context on limits, error handling, or authorization. The output schema exists, so return details are not required, but additional usage guidance would improve completeness.

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 meaningful explanations for all three parameters, including an example for 'ranges'. It adds value over the bare schema, though it could specify valid range formats or constraints.

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: 'Batch update multiple ranges in a Google Spreadsheet.' This verb+resource combination is specific and distinguishes it from alternatives like 'update_cells' (single range) among siblings.

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 indicates when to use this tool (for batch updates of multiple ranges). However, it does not explicitly state when not to use it or compare with siblings like 'update_cells' or 'append_rows', leaving some ambiguity for an AI agent.

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