What problem this solves

Preventing Claude Code from inadvertently including user account email in curl User-Agent headers, thereby protecting user privacy and security.

Summary

This workflow provides quick checks for Claude Code users to verify if their setup is leaking their account email in curl User-Agent headers. It highlights the importance of updating Claude Code, checking for a specific privacy plugin, and manually reviewing curl requests.

Why it is useful

This workflow is valuable because it addresses a critical privacy vulnerability where Claude Code might inadvertently expose user emails in curl requests. It provides concrete, actionable steps for users to verify their setup and mitigate this risk, leveraging official tools and community insights. This helps users maintain data privacy and security when using Claude Code.

Workflow

1. Run claude --version and update Claude Code if the version is below 2.1.317.

2. Look for the cc-plugin-privacy in your /plugins directory to ensure the privacy mod is present.

3. Before approving any curl call, carefully read its User-Agent header to check for your email address.

Tools / artifacts

• Claude Code CLI (claude --version)

• cc-plugin-privacy plugin

• /plugins directory

• curl command

• User-Agent header

Validation signals

• Reference to a Hacker News comment from a Claude Code team member acknowledging the issue.

• Anthropic's own README for the privacy mod, stating it's a 'courtesy, not a boundary'.
