create_voice_clone_from_path

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

With no annotations, the description fully covers behavior: copying the file under a fresh UUID, registering in DB, and returning metadata with hasAudio=true. It also discloses supported extensions and constraints. Minor omissions like error handling or disk space are acceptable for a creation tool.

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 extremely concise: two sentences pack the main action, constraints, supported formats, and follow-up tools. It is front-loaded with the verb 'Create' and contains no fluff.

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?

Given no output schema, the description explains the return value (metadata with hasAudio=true). It covers supported extensions, file requirements, and follow-up tools. It is adequately complete for a creation tool, though it lacks details on name uniqueness and error conditions.

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 coverage is 100%, and each parameter has a schema description. The tool description adds the list of supported audio extensions and the constraint that sourcePath must be readable, but does not significantly expand beyond the schema. Baseline 3 is 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 clearly states the tool's purpose: creating a voice clone from an audio file. It explains the entire workflow (copy, register, return metadata) and distinguishes itself from sibling tools by mentioning follow-up tools like list_voice_clones and set_active_voice_clone.

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 provides good usage context: supported audio formats, file existence requirement, and path confinement. It also suggests using list_voice_clones and set_active_voice_clone afterward. However, it does not explicitly state when not to use this tool (e.g., for cloud sources).

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