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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates this is a mutation tool ('Sets file-level sharing settings') and provides some context about its scope ('high-level tool for the most common permission changes'). However, it doesn't disclose important behavioral aspects like required permissions, whether changes are reversible, error conditions, or what the response contains. The description adds value but leaves significant gaps.

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 efficiently structured with three sentences that each serve a distinct purpose: stating the core function, providing usage context, and differentiating from alternatives. There's no wasted text, and the most important information (what the tool does) is front-loaded.

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 that this is a mutation tool with no annotations but with a complete input schema (100% coverage) and an output schema (indicated by 'Has output schema: true'), the description provides adequate context. It explains the tool's purpose, usage guidelines, and differentiation from siblings. The output schema means the description doesn't need to explain return values. However, for a permission-setting tool, more behavioral context about security implications would be beneficial.

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?

The schema description coverage is 100%, so the schema already documents all 5 parameters thoroughly. The description doesn't add any parameter-specific information beyond what's in the schema. According to the scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no parameter info in the description.

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 with specific verbs ('Sets file-level sharing settings and controls link sharing') and identifies the resource ('for a Google Drive file or folder'). It distinguishes this tool from its siblings by explicitly naming alternatives (share_drive_file, update_drive_permission) for different permission management scenarios.

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 explicit guidance on when to use this tool ('most common permission changes', 'toggle "anyone with the link" access or configure file-level sharing behavior') and when to use alternatives ('For managing individual user/group permissions, use share_drive_file or update_drive_permission instead'). This gives clear context for tool selection.

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