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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool 'gets' a shareable link, implying a read-only operation, but doesn't clarify if this requires specific permissions (e.g., viewer access), whether it modifies anything (e.g., changes sharing settings), or what happens on errors (e.g., if the file doesn't exist). For a tool with zero annotation coverage, this lack of behavioral details is a significant gap.

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 appropriately sized and front-loaded: the first sentence states the purpose clearly, followed by structured sections for Args and Returns. There's no wasted text, and each section earns its place by organizing information logically. However, the Returns section could be more precise (e.g., specifying it returns a string vs. multiple links).

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 tool's moderate complexity (2 parameters, no annotations, but has an output schema), the description is partially complete. It covers the purpose and parameters but lacks behavioral context (e.g., permissions, errors) and usage guidelines. The output schema exists, so the description doesn't need to detail return values, but the Returns section is somewhat vague ('The shareable links and current sharing status' might imply multiple outputs, while the schema suggests a single string).

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 0%, so the schema provides no parameter details. The description adds basic semantics by listing parameters with brief explanations: 'user_google_email (str): The user's Google email address. Required.' and 'file_id (str): The ID of the file or folder to get the shareable link for. Required.' This clarifies what each parameter represents, but doesn't provide format examples (e.g., email format, ID structure) or constraints, leaving gaps in understanding.

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: 'Gets the shareable link for a Google Drive file or folder.' It specifies the verb ('gets') and resource ('shareable link'), and distinguishes it from siblings like 'get_drive_file_permissions' or 'check_drive_file_public_access' by focusing on link retrieval rather than permissions or access checks. However, it doesn't explicitly differentiate from 'get_drive_file_download_url', which might be a similar sibling tool.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing proper permissions), exclusions (e.g., not for non-Google Drive files), or comparisons to siblings like 'get_drive_file_download_url' or 'check_drive_file_public_access'. The agent must infer usage from the purpose alone, which is insufficient for optimal tool selection.

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