update_spreadsheet_properties

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

With no annotations, the description carries the full burden for behavioral disclosure. It contains zero behavioral info: no mention of side effects, permissions, constraints, or what happens upon mutation. The description is entirely opaque.

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 extremely short (a single phrase), which is under-specified rather than concise. It fails to provide necessary detail, making it insufficient for effective tool usage.

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 description is completely inadequate for a tool with 5 parameters and no output schema. It explains nothing about what properties are updated, the return value, prerequisites, or behavior. Rich annotations and schema coverage do not compensate for missing context.

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?

Since the input schema has 100% description coverage (each parameter has a minimal Japanese description), the baseline is 3. The tool description adds no extra meaning beyond the schema's parameter descriptions, so a score of 3 is appropriate.

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 is a tautology: it simply restates the tool name as 'Update Spreadsheet Properties' in Japanese with an emoji. It does not specify the verb-resource combination or distinguish it from siblings like update_sheet_data or manage_sheet_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?

No guidance is provided on when to use this tool versus alternatives. No exclusions, prerequisites, or context for invocation are given.

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