text_scramble_animation

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

The description discloses the commercial license requirement, which is a behavioral constraint. However, with no annotations provided, the description should also mention whether the animation is reversible, performance impact, or any side effects. It meets a minimum but is not thorough.

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 concise: a single sentence with an emoji and key legal note. Every part earns its place, though it could be slightly more structured.

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?

For a tool with 5 parameters and no output schema, the description is too sparse. It does not describe the animation behavior, return value, or how parameters interact, leaving the agent underinformed.

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?

With 60% schema description coverage, the baseline is 3, but the description adds zero parameter semantics. It does not explain what 'chars', 'duration', or 'revealDelay' mean beyond the schema, missing an opportunity to clarify.

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 it is a text scrambling animation and notes the required commercial license. While the verb is implied, the emoji and Chinese text add context, distinguishing it from sibling text animation tools.

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 on when to use this tool versus other text animation tools like text_split_animation or text_reveal_animation. The description lacks context for selection.

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