create_audio

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

The description discloses that the operation is synchronous and returns the operation result, which adds behavioral context beyond the schema. However, it does not explain side effects, permissions, or error behavior, leaving a moderate gap given the absence of annotations.

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 two short sentences, front-loading the action and following with return behavior. It contains no redundant or filler content.

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?

With no output schema, the description's mention of returning the operation result is useful but underspecified. It does not clarify the result structure or common use cases, leaving the description only partially complete for a 5-parameter tool.

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 has 100% parameter description coverage, so the schema already defines each parameter. The description adds no parameter-specific meaning, making the baseline score of 3 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 specifies a synchronous Gemini Omni operation, with the parenthetical 'create audio' clarifying the tool's purpose. This distinguishes it from siblings like text_to_video and create_character, though the generic verb 'run' and lack of explicit 'preset' wording slightly reduce specificity.

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. Sibling tools exist (create_character, text_to_video), but the description does not mention conditions, exclusions, or selection criteria.

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