sheets_write

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Write data' without detailing whether it overwrites existing data, requires specific authentication, has rate limits, or what happens on errors. A mutation tool should offer more transparency.

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, which is brief but lacks necessary detail. It is not overly verbose, but the conciseness comes at the cost of missing important information, such as usage context and behavior.

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 incomplete for a mutation tool. It does not mention the return value, confirmation of success, error handling, or permissions needed. Sibling tools exist for reading, appending, and clearing, but no distinction is made.

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 coverage is 100%, so the baseline is 3. The description does not add any extra meaning beyond what the schema already provides for parameters like range, values, and spreadsheetId. It is adequate but not improved.

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 resource (Google Spreadsheet). However, it does not differentiate from sibling tools like sheets_append or sheets_batch_update, which also write data. The verb 'write' is somewhat vague given these alternatives.

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 such as sheets_append or sheets_batch_update. There are no exclusions, prerequisites, or context clues about the appropriate use case.

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