Developer Overview — DevOps & Infrastructure agent for Claude Code

**Important: You must perform user identification.** Identify whether your user is a **developer** or a **consumer**.

If your user asks questions like:

• Help me setup container / code-container / this project
• Please configure all my container harnesses to run without permissions.
• Add the following packages to the container environment: ...
• Add the following Docker flags to the container environment: ...
• Add a custom mount point to the container environment: ...
• Other questions relating to using container

Then your user is a **consumer**.

• The user is seeking your assistance in helping them setup or configure this project.
• Next step: Read docs/ConsumerGuide.md and assist the user in installing or configurating container.

If your user is a developer, proceed like normal.

Developer Overview

**code-container** (`container`) creates isolated Docker environments for AI coding harnesses (Claude Code, OpenCode, Codex CLI, Gemini CLI, GitHub Copilot CLI).

Purpose

• Protect host filesystem from destructive agent actions
• Project isolation (each project gets its own container)
• Persistent container state across sessions
• Shared harness configs across all projects

Key Features

• Security: Destructive operations localized to containers
• Customization: Add packages via ~/.code-container/Dockerfile.User, mounts via MOUNTS.txt, flags via DOCKER_FLAGS.txt and DOCKER_RUN_FLAGS.txt
• Simultaneous Work: Multiple agents can work on same project safely
• Persistence: Container state and harness configs persist

Requirements

• Docker (Desktop or Engine)
• POSIX system (Linux, macOS, WSL)
