Elevenlabs Security Basics

What it does

When your agent uses it

• Securing API keys
• Validating webhook signatures
• Auditing ElevenLabs security configuration
• With elevenlabs security

Example prompts

• “elevenlabs security”
• “elevenlabs secrets”
• “secure elevenlabs”
• “/elevenlabs-security-basics”

Requirements

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

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1API Key Management
2. 2Environment-Specific Keys
3. 3Webhook HMAC Signature Verification
4. 4Express Webhook Endpoint with Verification
5. 5API Key Rotation Procedure
6. 6Voice Data Protection

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
  • Grep

  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 bash).

  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 Security Basics loads about 1.5k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 573 words of instructions outside code blocks.

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

~100

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

~1.5k

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

~3.5k

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.

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.
