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 discloses several important behaviors: AI Studio run dispatches to Modal workers, files are deleted after processing, credits vary by model/file size, and some credits do not include AI Studio. However, it does not clarify whether the process is synchronous or how results are returned.

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 purpose, but includes excessive business details about credit packs, workspaces, and pricing links. The file deletion and credit requirements are useful, but sentences about workspace subscriptions and 'See mioffice.ai/pricing' add noise.

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 no output schema and no annotations, the description should explain the full usage flow, but it omits how to provide the video, what the translated result looks like, and how to obtain it. It focuses on credit costs and file deletion, leaving key operational details unclear for an agent.

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 input schema has 0 parameters, so the baseline is 4 per the rubric. The description does not add parameter-specific meaning, but none is needed since there are no arguments. It also doesn't explain how the video file is supplied, but that is not a parameter-level concern.

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 function: 'Translate and dub videos into other languages using AI.' This is a specific verb+resource+scope and distinguishes it from sibling tools like mio_ai_video_subtitler or mio_ai_text_to_video.

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 explicit guidance on when to use this tool versus alternatives. It mentions credit requirements and AI Studio, but does not compare it to other AI video tools or say when not to use it.

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