Import to Google Sheets

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

Annotations already mark the operation as non-read-only, non-idempotent, and non-destructive. The description adds relevant behavioral context beyond that: automatic conversion to native Google Sheets, preservation of rows, columns, sheets, and values, and a note that file_path avoids loading file contents into context. There is 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 compact and front-loaded: the first sentence states the core operation, the second clarifies conversion behavior, and the third gives targeted file_path guidance. Every sentence earns its place and there is no redundant restatement of schema fields.

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 output schema and fully documented input schema, the description covers the essential behavior and a key performance/context decision (file_path for large/batch imports). It does not explicitly contrast with create_spreadsheet or mention authentication prerequisites, but the missing guidance is minor and inferable from the sibling set.

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 coverage, the baseline is 3, and the description adds extra decision value by advising file_path for disk files and for batch operations. It also explains what conversion preserves, which helps callers interpret the results associated with file_name and source_format.

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 uses a specific verb and resource: 'Imports a spreadsheet (XLSX, XLS, ODS, CSV, TSV) into Google Sheets format with automatic conversion.' This clearly separates it from sibling importers like import_to_google_doc and import_to_google_slides by naming the target format and source types.

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 gives useful parameter-level guidance ('For batch operations, prefer file_path for files on disk so callers do not need to load full file contents into their context'), but it does not state when to use this tool versus alternatives such as create_spreadsheet or create_drive_file. Usage is implied rather than explicitly scoped.

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