convert_video_format

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

No annotations are provided, so the description carries the full burden. It does not disclose behavioral traits such as whether the input file is modified, the output location, or any side effects. The description focuses on parameters but lacks explicit behavioral context.

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 well-structured as a docstring with clear sections for Args and Returns. It is efficient and front-loaded, though the mixture of Chinese and English text is slightly inconsistent.

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 high parameter count (8), no output schema, and lack of annotations, the description is incomplete. It does not define the return type or discuss how hardware acceleration options affect behavior. The sibling list suggests more context is needed.

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?

With 0% schema coverage, the description adds meaning to all 8 parameters by listing them with explanations and examples (e.g., formats and codecs). This compensates well for the missing schema descriptions, though the 'quality' parameter could be more precise.

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 action (convert video format) and the resource (video files). However, it does not differentiate from sibling tools that also manipulate video files (e.g., compress_video, resize_video), making it slightly generic.

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 no guidance on when to use this tool, when not to use it, or how it compares to alternatives. Given the extensive sibling list, this omission is significant for the agent's decision-making.

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