A pre-configured slightly-sandboxed development environment using Claude Code with the --dangerously-skip-permissions yolo mode. Claude Code and common tools pre-installed.

You will have to re-authorize claude code with a plan or API key.

Originally based on the official Claude Code devcontainer at https://github.com/anthropics/claude-code/tree/main/.devcontainer

Features

Claude Code pre-installed and configured

Quick Start

Install the Dev Containers package in vscode. The package name is ms-vscode-remote.remote-containers in Microsoft's vscode and anysphere.remote-containers in Cursor.

Clone this devcontainer configuration to your audits directory:

git clone git@github.com:trailofbits/claude-code-devcontainer ~/audits/.devcontainer/

Open the audits folder in VS Code and select "Reopen in Container" when prompted, or use:
```
cd ~/audits
code .
```
VS Code will automatically build and start the development container. You may see this popup in the lower right.

Usage

The container runs as the ubuntu user with passwordless sudo access. Node.js and npm are available through nvm, and Claude Code is installed globally.

To verify the setup:

claude --version  # should show 1.0.x
claude doctor # shows config information
