Elevenlabs Hello World

What it does

When your agent uses it

• Starting a new ElevenLabs integration
• Testing your setup
• Learning basic TTS API patterns before wiring voice into a real app
• With elevenlabs hello world

Example prompts

• “elevenlabs hello world”
• “elevenlabs example”
• “elevenlabs quick start”
• “/elevenlabs-hello-world”

Requirements

• Python 3
• A credential in ELEVENLABS_API_KEY
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Bash(npm:*), Bash(node:*)

Workflow steps

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

1. 1SDK (TypeScript / Python) — batch generation with tuned voice settings.
2. 2cURL — the raw REST call, no SDK, for shell scripts and testing.
3. 3Streaming — the eleven_flash_v2_5 low-latency path (~75 ms first chunk).
4. 4Model / voice / output-format tables — the exact IDs to plug in above.

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(node:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • curl

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.elevenlabs.io

  Also links to:

  • 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 Hello World loads about 1.3k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 435 words of instructions outside code blocks.

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

~89

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

~1.3k

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

~2.8k

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.
