Elevenlabs Core Workflow B

What it does

When your agent uses it

• Converting one voice to another
• Generating sound effects from a text description
• Removing background noise from a recording
• Transcribing audio

Example prompts

• “elevenlabs speech to speech”
• “voice changer”
• “sound effects”
• “/elevenlabs-core-workflow-b”

Requirements

• A credential in ELEVENLABS_API_KEY
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Bash(npm:*), Bash(curl:*)

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

1. 1Speech-to-Speech (voice changer) — client.speechToSpeech.convert(voiceId, …)
2. 2Sound Effects — client.textToSoundEffects.convert({ text, … }) against
3. 3Audio Isolation — client.audioIsolation.audioIsolation({ audio }) against
4. 4Speech-to-Text — client.speechToText.convert({ audio, model_id: "scribe_v1" })

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Bash(npm:*)
  • Bash(curl:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • elevenlabs.io

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • ELEVENLABS_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Elevenlabs Core Workflow B loads about 1.6k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 479 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~107

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
