Import to Google Sheets

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

Annotations indicate a write operation (readOnlyHint=false) with no destructive or idempotent behavior. The description confirms it creates a new sheet via conversion, preserving content. It does not mention the original file is unchanged, but that is implicit. No contradiction with annotations.

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 4 sentences, front-loaded with the core purpose, followed by conversion details and usage guidance. Every sentence adds value, though it could be slightly 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?

Given the presence of an output schema (documenting return values) and the tool's moderate complexity (7 params, 2 required), the description covers conversion behavior, supported formats, usage recommendations, and a size warning. It adequately differentiates from siblings in 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?

With 100% schema description coverage, the schema already details each parameter. The description adds value by explaining the trade-off between content and file_path (e.g., file_path preferred for batch operations, warning about memory for large files), which supplements the schema.

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 (imports a spreadsheet into Google Sheets), lists supported formats (XLSX, XLS, ODS, CSV, TSV), and implies automatic conversion. It distinguishes from siblings like create_spreadsheet (creates empty sheet) and import_to_google_doc (imports to Docs).

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 offers explicit guidance: 'For batch operations, prefer file_path for files on disk so callers do not need to load full file contents into their context.' It also warns about file size limits. However, it does not explicitly state when not to use this tool (e.g., for creating empty sheets, use create_spreadsheet).

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