animate_to_bottube

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

With no annotations, the description adds some behavioral context: it always returns a dict, and the clip length is capped. However, it lacks information on side effects, authentication, or error handling, which are important for a multi-step creation tool.

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 extremely concise—two sentences that front-load the core functionality and key constraints. Every sentence provides valuable information without redundancy.

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 tool's complexity (11 parameters, combined pipeline, no output schema), the description is incomplete. It fails to explain the return dict structure, required prerequisites, or the meaning of most parameters, leaving significant gaps for correct usage.

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 schema description coverage is 0%, and the description only mentions 'action_id' and 'title' (required), ignoring the other 9 parameters. It does not explain the meaning or usage of optional parameters like 'model_url', 'fps', or 'resolution', leaving the agent without necessary guidance.

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: it takes a humanoid model, applies Meshy rig, animates with a specified action_id, renders the motion, and publishes a video to BoTTube. It explicitly distinguishes itself from a turntable, making the function unambiguous.

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 context by comparing the output to a turntable and noting it is a one-shot pipeline. However, it does not explicitly list when to use this tool versus siblings like 'animate_model' followed by 'upload_to_bottube', but the distinction is implied.

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