Check Drive File Public Access

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds the core behavioral context—searching by name and checking public link sharing status—which is consistent with annotations. It does not elaborate on edge cases like multiple matches or file-not-found, but these may be covered by the output schema.

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 a single, efficiently worded sentence with no filler. The main action and target are front-loaded, making it immediately clear what the tool does.

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 simple read-only nature of the tool, the presence of a rich output schema, and strong annotations, the one-sentence description is largely sufficient. It could be improved by noting differences from closely related siblings or handling ambiguous cases, but overall it covers the essential 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?

Schema description coverage is 100%, and every parameter (user_google_email, file_name, drive_id) already has a detailed schema description. The description only reiterates that the search is by name, adding no new meaning beyond what the schema provides, so the baseline score of 3 applies.

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 searches for a file by name and checks whether public link sharing is enabled. It uses specific verbs ('searches', 'checks') and names a concrete resource and condition, distinguishing it from permission or link-retrieval tools, though it does not explicitly name alternatives.

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: use this tool when you want to determine if a named Drive file has public link sharing enabled. However, it gives no explicit guidance on when to choose this over sibling tools like get_drive_shareable_link or get_drive_file_permissions, and no exclusions are stated.

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