create_title_card

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

With no annotations available, the description carries the full burden of behavioral disclosure. It does not state whether the tool is destructive, what it modifies (e.g., existing compositions), or any side effects. The vague 'with animations' does not clarify what animations are applied or whether they are configurable.

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 fluff. However, it is so brief that it feels under-specified rather than efficiently concise—key details are omitted that could be stated without adding length.

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 10 parameters, 0% schema coverage, no annotations, and no output schema, the description is far from complete. It fails to explain what a title card is, how animations work, what the return value might be, or how parameters interact. A tool of this complexity requires substantially more documentation.

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%, yet the description provides no insight into any of the 10 parameters (e.g., what 'style' enum values mean, how 'color' or 'backgroundColor' are structured, what 'compId' or 'compName' refer to). The description adds no meaning beyond the raw parameter names in the schema.

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 resource ('title card'), with an added detail ('with animations') that hints at output characteristics. This clearly distinguishes it from sibling tools like create_lower_third or create_text_animator, which address different visual elements.

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 such as create_lower_third or create_text_animator. There is no indication of prerequisites, context requirements, or exclusions, leaving the agent to infer usage from the tool name alone.

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