Secure Your AI Agents: Comprehensive Guide for Codex & Claude

This skill provides guidance on securely operating AI coding agents such as Codex and Claude. It addresses critical security aspects, including sandboxing, permission and command configurations, containerization, secrets management, network egress, token privileges, and prompt-injection risk. Use this guide to proactively audit and enhance the security posture of your AI agents.

What this skill does

• Audits whether AI coding agents run in a sandboxed environment.
• Configures permissions and controls over potentially dangerous commands.
• Supports the use of containerized environments for AI agents.
• Manages sensitive information by ensuring secrets are kept out of the agent's context.
• Examines network egress and token privileges to maintain least privilege access.
• Evaluates the risk of prompt injection and the privacy implications of agent usage.

Who it is for

This skill is designed for developers and teams utilizing AI coding agents, including Claude Code, Cursor, and Codex users, who need to ensure the secure operation of these agents as part of their software development processes.

Use cases

• Securing AI agents when permission gating is disabled or secrets are exposed to the agent's shell.
• Running coding agents safely while processing untrusted code or web content.
• Protecting personal or confidential data during cloud-based AI agent activity.
• Improving the security of a project's attack surface by auditing AI agent operations.
