check_drive_file_public_access

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

Discloses that it checks first match, requires drive.readonly scope, and is a helper for embedding. However, does not explicitly state output format or error behavior (e.g., if no file found). Still good for a simple tool with no 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?

Concise, well-structured with main action first, then context and alternatives. Every sentence adds value. No redundancy.

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 simplicity and presence of an output schema, the description covers purpose, usage context, sibling differentiation, and OAuth requirement. It is self-contained and 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?

Schema coverage is 100% so baseline is 3. Description adds context about filename search and multiple matches but does not elaborate on the email parameter. Sufficient overlap with schema.

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 'Search' and 'report' with specific resource 'whether file is publicly linked'. Differentiates from sibling 'get_drive_file_permissions' for specific files. Aligns with Google Docs embedding use case.

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?

Explicitly states when to use (before insert_doc_image), limitation (checks first if multiple matches), and alternative for specific file (get_drive_file_permissions). Also mentions required OAuth scope.

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