replicate_voice_to_isolated_environment

Replicate a voice into another workspace's isolated data residency, keeping the same voice ID by default or assigning a new one.

Instructions

Replicate Voice To Isolated Environment

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "voice_id": "<voice_id>",
      "target_workspace_id": "<target_workspace_id>"
    },
    "name": "replicate_voice_to_isolated_environment"
  }
}

Input Schema

NameRequiredDescriptionDefault
voice_idYesVoice ID to be used, you can use https://api.elevenlabs.io/v1/voices to list all the available voices.
preserve_voice_idNoWhen true (default) the replicated voice keeps the same voice ID in the target residency; set to false to assign a new voice ID.
target_workspace_idYesID of the workspace to replicate the voice into. It must belong to the same consolidated billing group as the calling workspace; the target's data residency is derived from that link.

Behavior2/5

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

Annotations declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false, which covers the basic safety profile. However the description adds zero behavioral context beyond the name — nothing about cross-workspace side effects, whether the source voice is affected, or permission requirements. With annotations present the bar is lower, but this still contributes nothing.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is not concise in a useful sense — it is under-specified. It repeats the tool title with no front-loaded information an agent could act on, so the brevity does not earn its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a mutation tool that crosses workspace/data-residency boundaries with no output schema and no description guidance. The critical prerequisite (same consolidated billing group) lives only in the schema, and the description never explains the operation's effect, so completeness is inadequate for what an agent needs before invoking it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The schema itself fully documents voice_id, preserve_voice_id, and target_workspace_id (including the consolidated-billing-group constraint); the description adds no parameter meaning on top of it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description is verbatim the tool title/name, 'Replicate Voice To Isolated Environment.' While it names a verb and resource, it is a tautological restatement of the identifier and adds no distinguishing detail versus siblings like add_voice, create_voice, or edit_voice.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance whatsoever on when to use this tool versus the many other voice-management siblings (add_voice, create_voice, edit_voice, add_sharing_voice). No prerequisites, no exclusions, nothing.

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