enhance_video_sync

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

No annotations are provided, so the description must disclose all behavioral traits. It explains synchronous blocking and upload types, but fails to mention side effects (e.g., file modifications, temporary storage), error behavior, or cancellation support. Coverage is adequate but lacks depth.

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 front-loaded with the main purpose and uses bullet-like formatting for methods. It is relatively concise but includes some redundancy (e.g., video_source description matches schema). Well-structured overall.

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?

With no output schema, the description should explain the return value (e.g., enhanced video URL or metadata). It also lacks prerequisites, file size limits, or error handling details. Given the tool's complexity, this is a significant gap.

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 schema already documents all parameters. The tool description adds context about upload methods but largely repeats schema info. With high coverage, baseline 3 is appropriate; no additional semantics are offered beyond what the schema provides.

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 verb ('enhance'), resource ('video'), and mode ('synchronously, blocking wait'). It distinguishes from sibling tools ('create_task', 'get_task_status') which are asynchronous task management, while this tool is a synchronous operation.

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 explains the two upload methods (URL vs local) and the blocking nature, implying synchronous use. However, it does not explicitly contrast with asynchronous alternatives or state when not to use this tool, which would be more helpful.

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