Elevenlabs Core Workflow A

What it does

When your agent uses it

• Building TTS features
• Cloning voices from audio samples
• Streaming speech to a chatbot
• Implementing the primary ElevenLabs money-path: voice generation

Example prompts

• “elevenlabs TTS”
• “text to speech”
• “voice cloning elevenlabs”
• “/elevenlabs-core-workflow-a”

Requirements

• 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 step headings in SKILL.md.

1. 1Advanced Text-to-Speech
2. 2Instant Voice Cloning (IVC)
3. 3WebSocket Streaming TTS
4. 4Voice Management

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 no API keys, tokens, secrets or passwords.

  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 A loads about 1.6k tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 523 words of instructions outside code blocks.

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

~98

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

~3.7k

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.
