generate_svg_animation

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

With no annotations, the description bears full responsibility for disclosing behavioral traits. It omits critical details such as whether the tool modifies the input file, what happens to existing files at output_path, or any requirements for the SVG content. The sparse description leaves much to inference.

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 concise (one sentence, nine words), which is acceptable for a simple tool. However, it lacks structure (e.g., no front-loading of important constraints or behaviors) and could be slightly expanded to improve usability without becoming verbose.

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 tool's generative nature, the description is incomplete. It does not explain the output animation format, any side effects, or potential limitations. Without an output schema, the agent receives no information about what the tool returns, leaving a significant gap.

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?

The input schema covers 100% of parameters with clear descriptions. The tool description adds no additional meaning beyond the schema, but the schema itself is sufficiently descriptive for each parameter, making the baseline score appropriate.

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 the action 'Generate an SVG animation' and identifies the resources ('from a source file and prompt'). It is specific enough to convey the core functionality without confusion.

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?

The description provides no guidance on when to use this tool versus alternatives (though none are listed), nor does it mention any preconditions or exclusions. It only states what the tool does, not when it should be used.

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