batch_write_ranges

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

With no annotations, the description bears full responsibility for disclosing behavioral traits. It only mentions idempotency, but omits critical details like side effects (e.g., overwriting data), authentication needs, rate limits, or error behavior. Significant gaps remain.

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 sentence with no wasted words, achieving high conciseness. However, it sacrifices completeness for brevity. It could include more detail while remaining efficient, hence not a 5.

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?

Despite having an output schema (not shown), the description does not explain return values, the structure of the data array, or the behavior of the optional value_input_option parameter. Given the tool's complexity (nested objects, enums), the description is far from complete.

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 the description must elaborate on parameters. It provides zero information about spreadsheet_id, data (the array of BatchWriteRange objects), or value_input_option (though an enum is defined). The agent cannot infer correct parameter usage from the description alone.

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 'write' and the resource 'several rectangular ranges', and includes 'idempotent' as a key qualifier. It distinguishes this tool from siblings like write_range (single range) and batch_read_ranges (read), making its purpose unambiguous.

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 implies use for batch writing multiple ranges, but it does not explicitly state when to use this tool versus alternatives like write_range, nor does it mention any prerequisites or when not to use it (e.g., for non-rectangular writes). The context is clear but lacks exclusions.

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