upload_drive_file

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

No annotations provided, so description must carry full behavioral burden. Only states 'Upload a file' but omits critical details: overwrite behavior, authentication requirements, return value, synchronicity. For a mutation tool, this is insufficient.

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?

Extremely concise (one sentence) but at the cost of substance. Could be restructured to include key behavioral info without losing conciseness. Earns its place as a statement of purpose but not much more.

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?

No output schema, so description should explain return value (e.g., file ID). Does not mention that upload requires local file path, or that parent_folder_id and mime_type are optional. Incomplete for a 4-parameter tool with no output schema.

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% with adequate descriptions for all 4 parameters. Description 'Upload a file to Google Drive.' adds no additional semantic value beyond schema. Baseline 3 is appropriate.

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?

Clear verb and resource: 'Upload a file to Google Drive.' Distinct from siblings like copy, delete, download, and even save_gmail_attachment_to_drive which handles email attachments not local files. Could be more explicit about 'local file upload' but adequate.

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 vs alternatives. No mention of prerequisites, when not to use, or comparisons with other upload-like tools (e.g., bulk_save_gmail_attachments_to_drive). Single sentence with no usage context.

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