modify_sheet_values

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

Discloses write/update/clear behavior and parameter defaults, but misses the dry_run parameter (present in schema). No mention of error handling or atomicity. Adequate but not thorough.

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?

Well-structured with Args/Returns sections, but slightly verbose. Each sentence adds value, but could be more concise.

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?

Covers most parameters and return type; lacks explanation of edge cases and parameter interactions. Output schema not provided, but return value described. Reasonably complete for moderate complexity.

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?

Adds meaning beyond schema by explaining value formats, input options, and clear_values behavior. However, dry_run is undocumented and values schema type is simplified.

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?

Clearly states it modifies values in a Google Sheet, listing write/update/clear operations. Differentiates from siblings like read_sheet_values and format_sheet_range.

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?

Implies usage for modifying sheet values but lacks explicit guidance on when to use vs alternatives like batch_update_doc or clear_completed_tasks. No exclusions or conditions provided.

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