sheets_update_table

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

No annotations provided, so description must carry full burden. It only says 'update' but doesn't disclose permissions required, reversibility, side effects (e.g., whether existing data is affected), or what happens to unspecified fields. Lacks crucial behavioral context.

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 very concise (one sentence, 8 words) and front-loaded with key action and resource. However, it could be slightly more informative while remaining concise; still, no wasted words.

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?

With 7 parameters, no output schema, and no behavioral details, the description is incomplete. It doesn't explain what the update does to the table structure, how fields mask works, or return value. Should provide more context for a non-trivial mutation.

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%; all parameters have descriptions. The description adds no extra meaning beyond 'Update... by tableId'. Baseline 3 is appropriate as the schema does the heavy lifting.

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 the specific action 'Update', the resource 'existing native Google Sheets table', and the identifier 'tableId'. It clearly distinguishes from siblings like sheets_add_table (create) and sheets_delete_table (delete).

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 on when to use this tool versus alternatives, prerequisites (e.g., tableId from getTables), or when not to use it. Implicit differentiation from siblings is possible but not stated.

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