enhance_video_sync

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It explicitly states 'blocking wait for completion', explains the automatic upload of local files to TOS storage, and mentions polling parameters, giving good transparency. It does not mention side effects, but given the nature, none are expected.

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 with bullet points and clear categorization of upload methods and parameters. Every sentence serves a purpose, and there is no redundancy or unnecessary detail.

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 description covers the blocking nature, upload methods, and all parameters thoroughly. It lacks an explicit description of the return value, but given the synchronous nature, it likely returns the enhanced video. Overall, it is fairly complete for a tool without an output schema.

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%, so the baseline is 3. The description adds context beyond the schema, such as the automatic upload process for local files and that URLs must be publicly accessible. This extra information enhances understanding of parameter usage.

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: to enhance video synchronously, with a blocking wait. It details two upload methods (URL and local), distinguishing it from sibling tools that handle different operations like task creation or status checking.

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 and the blocking nature, implicitly indicating when to use the tool. However, it does not explicitly contrast with siblings like create_task (likely async) or provide when-not-to-use guidance, making usage guidelines less explicit.

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