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

No annotations are provided, so the description bears full burden. It discloses 'time-limited one-time' behavior but does not detail side effects, permissions, revocation, or return format. For a generated key tool, additional transparency about scope and limitations would be valuable.

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 sentence that immediately conveys the action and scope. It is front-loaded with the core purpose and contains no extraneous words, earning maximum conciseness.

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?

The tool is simple with only two parameters, but the description does not specify the return format or potential error scenarios. Given the lack of output schema, additional context about what the generated key includes or how to use it would improve completeness.

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% with descriptions for both 'key' and 'expire' parameters. The description summarizes the tool's function but does not add semantic meaning beyond what the schema already provides, resulting in a baseline score of 3.

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: generating a time-limited one-time access key for a video key (Level 2) or file key (Level 3). It uses a specific verb ('Generate') and resource ('access key'), and distinguishes from sibling tools that handle captions, uploads, or other operations.

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 for generating access keys but provides no explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. The sibling list shows many video-related tools, but no clear alternative is indicated.

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