upload_voice_material

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

Annotations already indicate a non-read-only, open-world, non-idempotent, non-destructive operation. The description adds the 'permanent' persistence detail and confirms the upload behavior, but it does not disclose file format constraints, size limits, authentication needs, or what exactly is returned beyond the existing output schema.

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 entire description is one short, front-loaded sentence. It states the action, source, and result without filler, and every word contributes meaning.

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 single-parameter upload tool with an output schema available, the description covers the core behavior: local audio becomes permanent voice material. Details like supported audio formats, size limits, or callback behavior are absent, but the tool is simple enough that the description is largely sufficient.

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 schema only provides the parameter name 'file_path' with no description. The description adds that the path refers to a local audio file, which gives some semantic grounding. However, it does not specify expected formats, path conventions, or constraints, so the compensation for the 0% schema description coverage is only partial.

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 a specific verb ('upload'), resource ('local audio'), and result ('permanent voice material'). It distinguishes this from sibling tools like upload_video_material or upload_content_image by naming the exact asset type and persistence.

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 implies the tool is used when the agent needs to upload a local audio file as a permanent voice asset, but it does not explicitly state when to use it over alternatives such as upload_video_material or upload_content_image. No exclusions or alternative guidance are provided.

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