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

The description adds meaningful behavior beyond the annotations: it discloses the required OAuth scope (file.read), the conditional output behavior (save to outputDir vs. return content), the text/base64 distinction, and the 5MB size limit. This is rich, actionable behavioral information. No contradiction with annotations is present.

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 compact and well-structured. The opening sentence states the core purpose, followed by auth requirements, output behavior, and a critical size constraint. Every sentence earns its place with no unnecessary filler.

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?

For a download tool with no output schema, the description adequately covers authentication, return behavior, and file-size restrictions. Minor gaps remain, such as the exact result when saving to outputDir and behavior on errors, but the essential invocation context is present.

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%, so the baseline is 3. The description goes beyond the schema by explaining the outputDir-dependent behavior, the text/base64 return format, and the 5MB constraint. This adds real semantic value for invoking the tool correctly.

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 verb and resource: '드라이브 파일을 다운로드합니다' (downloads drive file). It is specific and understandable, but it does not explicitly differentiate from the sibling nworks_sharedrive_download, so the agent must rely on tool naming to distinguish them.

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 gives clear context for when to use the tool and how its behavior changes based on outputDir. However, it does not mention when NOT to use it or name sibling alternatives, so the guidance is clear but not fully comparative.

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