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

With no annotations, the description carries the full burden of behavioral disclosure. It explicitly describes the return contract: ok=True with watch_url on success, and ok=False with error/failed_stage and partial artifacts on known stage failures. It does not mention external side effects beyond the obvious YouTube upload or long-running execution, but the pipeline framing and timeout parameter partially cover that.

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 very compact: one pipeline line and one short return-contract paragraph. It is front-loaded with the core purpose and every sentence provides useful information without fluff or repetition.

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?

This is a multi-stage, 16-parameter tool with no output schema and no annotations, yet the description only provides high-level pipeline context and the return format. It does not explain the stages, parameter semantics, expected failures, or the relationship between all the configuration knobs, leaving an agent under-informed for correct invocation.

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% and the description does not explain any of the 16 parameters. Only 'prompt' appears in the pipeline, and 'title' is implied by YouTube upload, but there is no guidance on fps/frames/duration, should_emesh, texture_prompt, category_id, privacy, or made_for_kids. The description fails to compensate for the schema's lack of parameter descriptions.

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 shows a one-shot end-to-end pipeline from prompt to YouTube upload, which distinguishes it from sibling stage tools. It lacks an explicit action verb like 'orchestrates' or 'executes,' but the arrow chain makes the purpose unmistakable.

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 word 'One-shot' implies this tool should be used when the complete pipeline is desired in a single call rather than manually assembling sibling tools. However, it does not explicitly name alternatives, prerequisites, or situations where the user should instead call generate_3d_model, upload_to_youtube, etc. individually.

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