get_voice_preview

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

No annotations are provided, so the description carries the full behavioral burden. It discloses that the tool writes a local MP3 file and does not generate a new sample, but it omits important behavior such as whether an existing file is overwritten, how the local path is resolved, permission requirements, and error behavior.

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 redundant wording. Every phrase contributes to identifying the operation and its key distinction from generation.

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?

For a simple two-parameter download tool with no output schema, the description gives the core purpose and output type. However, with no annotations and no parameter descriptions, it leaves meaningful gaps around filename handling and local file behavior.

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%, so the description should compensate for both required parameters. It implicitly maps generated_voice_id to an existing preview and filename to the local MP3 target, but it does not explain the ID format, whether filename is a basename or full path, allowed extensions, or overwrite semantics.

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 states a specific verb and resource: downloads an existing generated voice preview to a local MP3 file. It also distinguishes the operation from generating a new sample, which helps separate it from voice-generation siblings such as design_voice or generate_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?

The phrase 'existing generated voice preview' and 'without generating a new sample' implies when to use it, but the description does not explicitly name alternatives or fully clarify when to choose this over related tools like get_voice or create_voice_from_preview.

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