Build Short Video Payload

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds that no provider API is called, reinforcing safety. However, no extra behaviors (e.g., error handling, output format) are disclosed, so the description adds moderate value.

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 with no redundancy or filler. It conveys the core functionality efficiently.

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 has 14 parameters, no output schema, and no parameter descriptions. The description does not explain what the payload is, how it varies by provider, or what to do with the output. The tool is complex, yet the description provides barely any context.

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 0%, yet the description provides no explanation of parameters. With 14 parameters including enums and defaults, the absence of parameter semantics leaves the agent with no guidance beyond schema types and defaults. This is a critical gap.

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 action (build) and the resource (provider-specific request payload). It also specifies that no provider API call is made, which sets it apart. However, it does not explicitly differentiate from sibling tools like short_video_generate, though the implication is strong.

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 use when preparing a payload without executing it, but provides no explicit guidance on when to use versus alternatives (e.g., short_video_generate). It does not mention prerequisites, exclusions, or context.

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