What it does

Retellai Security Basics is an agent skill from jeremylongshore/tons-of-skills-marketplace. Retell AI security basics — AI voice agent and phone call automation. Use when working with Retell AI for voice agents, phone calls, or telephony. Trigger with phrases like "retell security basics", "retellai-security-basics", "voice agent".

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/security-patterns.md`). Compatibility notes: Designed for Claude Code

It sits in AI & LLM Engineering, covering Speech recognition and synthesis and Prompt injection and agent security. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Working with Retell AI for voice agents
  • With phrases like retell security basics
  • Retellai-security-basics

Example prompts

  • “retell security basics”
  • “retellai-security-basics”
  • “voice agent”
  • “/retellai-security-basics”

Requirements

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

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
    • Edit
    • Bash(npm:*)
    • Bash(curl:*)
    • 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 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):

    • docs.retellai.com
    • npmjs.com

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

  • Credentials

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

    • RETELL_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

Retellai Security Basics loads about 512 tokens when it runs, and up to ~1k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 151 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~512
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

Retell AI Security Basics

Overview

Implementation patterns for Retell AI security basics — voice agent and telephony platform.

Prerequisites

  • Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern
typescript
import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);

Output

  • Retell AI integration for security basics

Error Handling

ErrorCauseSolution
401 UnauthorizedInvalid API keyCheck RETELL_API_KEY
429 Rate LimitedToo many requestsImplement backoff
400 Bad RequestInvalid parametersCheck API documentation

Examples

Rotate an exposed development credential safely

Disable the exposed development key in the provider console, create a scoped replacement, and update only the development secret reference. Verify the new key with a harmless agent-list request while ensuring command output does not print its value. Review access logs and affected preview configurations, then document the incident with the credential identifier and rotation time rather than copying key material into the ticket or source repository.
