CRITICAL: Never use Read, Edit, or Write tools on ~/.cyrus/.env or any file inside ~/.cyrus/. Use only Bash commands (grep, printf >>, etc.) to interact with env files — secrets must never be read into the conversation context.

Setup Claude Auth

Configures Claude Code credentials so Cyrus can run AI sessions.

Step 1: Check Existing Auth

Check if credentials are already configured:

grep -c -E '^(ANTHROPIC_API_KEY|CLAUDE_CODE_OAUTH_TOKEN)=' ~/.cyrus/.env 2>/dev/null || echo "0"

If the count is >= 1, inform the user:

Claude Code authentication is already configured. Skipping this step. To reconfigure, remove the existing key from ~/.cyrus/.env and re-run this skill.
