game_create_animation

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 behavioral disclosure. It only states that an animation is created and does not explain whether existing animations with the same name are overwritten, what side effects occur on the AnimationPlayer, or what the resulting animation object contains.

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 that starts with the action verb and contains no filler. It is appropriately concise, though it is also quite sparse for a six-parameter tool.

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?

With no annotations and no output schema, the description must provide more context than it does. It does not explain how tracks and keyframes are structured, whether the animation is added to an existing library, or how the operation behaves on the AnimationPlayer. The complexity of the tool's parameters is not matched by the description's content.

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 100%, so all six parameters already have individual descriptions. The phrase 'tracks and keyframes' adds a small hint about the tracks array, but it does not substantially extend or clarify the schema's parameter documentation.

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-resource pair ('Create an animation') and adds the key content ('with tracks and keyframes'), making the tool's purpose clear. It does not explicitly differentiate from siblings like game_play_animation or game_tween_property, but 'create' is a distinct action.

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 use this tool versus closely related siblings such as game_play_animation, game_tween_property, or game_animation_control. The intended usage is only implied by the verb 'create,' with no mention of prerequisites like an existing AnimationPlayer or common alternatives.

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