text_typewriter_animation

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

With no annotations, the description must disclose behavioral traits. It provides no information about whether the tool modifies DOM, is destructive, requires specific element types, or how it handles existing content. This is a critical gap.

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?

While only one sentence, it is too brief and under-specified. It provides no structured information, front-loading nothing useful. True conciseness would include essential details without verbosity.

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?

Despite moderate complexity (5 parameters, no output schema), the description is completely inadequate. It fails to explain the typewriter effect, cursor behavior, or interaction with page elements, leaving the agent without sufficient context.

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% with adequate param descriptions (e.g., '要显示的文本'). The description adds no additional meaning beyond the schema, meeting the baseline of 3 for high coverage.

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 '打字机效果动画' is a tautology, repeating the tool name in Chinese without specifying the action or resource. It does not clarify that the tool animates text by revealing characters one by one in a target element.

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 usage guidance is provided. The description does not indicate when to use this tool versus sibling tools like text_reveal_animation or text_scramble_animation, leaving the agent without differentiation.

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