update_sheet_titles_tool

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

No annotations are provided, so the description must disclose behaviors. It only states the action without mentioning side effects (e.g., overwriting existing titles), permission requirements, or reversibility. The schema covers parameters, but the description adds minimal 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 a single, front-loaded sentence that conveys the core action. It is efficient with no extraneous text. However, it is very brief, which limits the depth of information.

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?

For a simple tool with three required parameters and an output schema (not shown), the description is adequate but not complete. It lacks context on return values, error conditions, or typical use cases. The presence of an output schema reduces the need to describe return values, but the description could still be more informative.

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 100%, so each parameter has a meaning. The description does not add additional semantics beyond the schema. Baseline score of 3 is appropriate as the schema already does the work.

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 verb (Update) and resource (sheet titles in a Google Spreadsheet). It distinguishes from sibling tools like update_spreadsheet_title_tool and update_table_title_tool by specifying 'sheet titles'. However, it could be more precise by mentioning that it renames sheets.

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 provides no guidance on when to use this tool versus alternatives like create_sheets_tool or delete_sheets_tool. It does not mention prerequisites, context, or exclude scenarios, leaving the agent to infer usage from the name alone.

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