link_local_file

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

No annotations are provided, so the description carries the full behavioral burden. It discloses that 'dry_run' previews the operation without updating metadata, and lists required parameters. However, it does not explain whether linking overwrites existing links, what permissions are needed, or the outcome (e.g., success/failure). This is adequate but not comprehensive.

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 concise: a one-sentence purpose followed by a clear, bullet-like list of parameters. Every sentence provides necessary information without redundancy. It is front-loaded and easy to scan.

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 (not shown but indicated), the description need not detail return values. It covers input parameters well, but could mention potential side effects (e.g., unlinking previous links) or confirmation after dry run. For a linking tool, it is largely complete.

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 0% schema description coverage, the description fully compensates by describing each parameter: 'user_google_email' as required, 'local_path' with an example, 'file_id' with type and alias example, and 'dry_run' with default and behavior. This adds significant meaning beyond the parameter names.

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 tool's purpose: 'Link a local file to a Google Drive file ID for synchronization.' It uses a specific verb ('Link') and resource ('local file to Google Drive file ID'), distinguishing it from sibling tools like 'upload_folder' or 'mirror_drive_folder' which have different scopes.

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 implies usage for synchronization but provides no explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as needing the file to already exist, or when not to use it. Sibling tools like 'upload_folder' or 'mirror_drive_folder' are not compared.

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