clone_voice

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

With no annotations provided, the description carries the full burden. It only mentions audio duration requirements and the word 'instant' but does not disclose other behavioral traits like persistence of clone, rate limits, destructive actions, or how to use the cloned voice later.

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?

Two sentences, no wasted words. First sentence states purpose clearly, second gives requirements and trigger phrases. Highly efficient.

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?

Adequate for a cloning tool with 4 params and no output schema, but lacks guidance on post-cloning usage (e.g., how to reference the cloned voice in other tools like text_to_speech). Could be more complete.

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%, so baseline is 3. The description adds no additional meaning to parameters beyond what the schema already provides (e.g., trigger phrases are not parameter-specific).

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 ('instant voice clone'), and mentions the required input (audio samples). It clearly differentiates from sibling tools like text_to_speech or speech_to_speech.

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?

Provides a requirement for audio duration (1-2 minutes) and trigger phrases, but does not explicitly state when to use this tool versus alternatives (e.g., text_to_speech, voice_isolation). Lacks exclusion criteria.

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