create_bouncing_object

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

No annotations are provided, so the description carries the full burden of disclosing behavior. It says only that an animation is created; it does not state what kind of output is produced, whether files are written, whether the operation is deterministic, or what 'physics-inspired' means concretely (e.g., gravity affects the ball).

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 front-loaded sentence with no filler words; every word contributes to the core concept. It is appropriately concise, though it sacrifices useful detail for brevity.

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 four undocumented parameters, no annotations, no output schema, and many overlapping sibling tools, this description is under-specified. An agent can infer the basic intent but cannot confidently understand gravity units, duration semantics, output behavior, or when to prefer this over a sibling tool.

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?

All four parameters have 0% schema description coverage, and the description adds nothing about width, height, gravity, or duration. Units and expected ranges for gravity and duration are entirely unclear, leaving the agent to guess or rely on defaults.

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 uses a specific verb ('Create') and a clear resource ('a physics-inspired bouncing ball animation'), which separates it from many sibling animation tools by naming the exact subject matter. It does not explicitly contrast itself with similar create_* tools like create_moving_object_video or create_custom_animation, so it stops short of full differentiation.

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?

There is no guidance on when to choose this tool over the many similar animation tools (e.g., create_moving_object_video, create_particle_animation, create_custom_animation). The intended use is implied by the name and the word 'bouncing,' but no conditions, exclusions, or alternative recommendations are provided.

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