parallel_animation

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

No annotations are provided, and the description does not disclose any behavioral traits. It does not explain how the tool handles parallel execution, duration, or animation order. The schema reveals syncMode and animations but the description adds no context.

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 short (one word), but this is under-specification rather than conciseness. It does not front-load useful information or justify its brevity by relying on rich schema or annotations.

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 complexity of the tool (parameters with enum and nested array objects, no output schema, no annotations), the description is wholly inadequate. An agent cannot infer when or how to invoke the tool correctly.

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%, meaning no parameter descriptions exist in the schema. The description adds no meaning beyond parameter names. For a tool with enum and array parameters, this is insufficient for an agent to understand values and usage.

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 is simply '并行动画' (Chinese for 'parallel animation'), which is a tautology of the tool name. It does not specify what the tool does, what resources it acts on, or how it differs from sibling tools like sequence_animation or sync_timeline.

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?

No guidance is provided on when to use this tool versus alternatives. Among many sibling tools (e.g., sequence_animation, create_sync_timeline), there is no indication of the intended use case.

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