sound_voice_batch

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the tool writes files, requires authentication, has side effects, handles batching, or what 'retain' implies operationally; the single ambiguous sentence is inadequate.

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 short, but its brevity reflects under-specification rather than efficient communication. The single sentence is confusing and front-loads an obscure term instead of actionable information.

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?

Although an output schema exists (so return values need not be explained), the description leaves almost everything else missing: no purpose clarity, no usage context, no parameter meanings, and no behavioral traits for a tool with three optional parameters and no annotations.

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% for three parameters (plan, request, project_root), and the description adds no meaningful semantics. It mentions 'request' and 'plan' only as English words without tying them to the parameters, and never mentions project_root.

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 is vague and ambiguous, using obscure phrases like 'Retain local caption speech' and 'run the synthetic plan demo' that do not clearly state the tool's core function. It fails to distinguish this batch sound/voice tool from its many siblings such as sound_mix_render or video_batch.

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?

There is no guidance on when to use this tool versus alternatives. The 'or' hints at two possible modes but gives no conditions or prerequisites for choosing either, leaving the agent with no routing information.

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